Delicious Banana Oatmeal Bars are the kind of simple homemade snack that makes busy mornings feel a little more manageable. They are soft, chewy, naturally sweet from ripe bananas, and hearty enough to pack for breakfast, lunchboxes, afternoon snacks, or a quick post-workout bite.
These bars come together with everyday ingredients: ripe bananas, rolled oats, honey or maple syrup, eggs, baking powder, and vanilla extract. Nothing complicated, nothing fussy, and no long ingredient list standing between you and a pan of warm, cozy oat bars.
The best bananas for this recipe are the freckled ones sitting on the counter that look almost too ripe for anything else. Those soft, spotted bananas mash easily and bring sweetness, moisture, and classic banana flavor to every bite.
Rolled oats give the bars their chewy structure. They make the bars feel more satisfying than a soft muffin, but still tender enough for kids and easy snacks.
A little honey or pure maple syrup adds sweetness without needing refined sugar in the batter. Honey gives a gentle floral sweetness, while maple syrup brings a deeper cozy flavor.
Eggs help bind everything together so the bars hold their shape once cooled. For a vegan version, flax eggs work too, using 2 tablespoons ground flaxseed mixed with 5 tablespoons water.
What makes these bars so useful is how forgiving they are. If the batter feels a little dry, add a splash of milk; if it seems too wet, stir in another handful of oats.
You can keep them plain and simple or dress them up with chocolate chips, nuts, cinnamon, nutmeg, dried fruit, coconut flakes, sunflower seeds, or a drizzle of peanut butter. Just keep the total add-ins around ¾ cup so the bars still hold together.
Delicious Banana Oatmeal Bars are warm, practical, and comforting. They taste like a homemade snack made for real life: quick mornings, hungry kids, lunchbox gaps, freezer emergencies, and those moments when you want something sweet but still simple.

Why You’ll Love These Delicious Banana Oatmeal Bars
These bars are easy to make. You need one bowl, one spoon, and a baking pan.
They are great for breakfast or snacks. The texture is soft, chewy, and satisfying.
They use simple ingredients. Ripe bananas, oats, eggs, honey or maple syrup, baking powder, and vanilla create the whole base.
They are kid-friendly. The bars taste sweet and cozy while still using oats and bananas.
They are meal-prep friendly. Bake a batch and keep them ready for grab-and-go snacks.
They freeze well. Wrapped individual bars can be stored for up to 3 months.
Recipe Details
This recipe bakes at 350°F (175°C). Use an 8×8-inch baking pan.
Line the pan with parchment paper, leaving a little overhang on the sides. This makes it easy to lift the bars out after baking.
If you do not have parchment, grease the pan with butter or coconut oil. Do not skip pan preparation.
The banana base uses 3 ripe bananas, about 1 ½ cups mashed. The spottier the bananas, the sweeter they will be.
The oat base uses 2 cups rolled oats. Do not use instant oats if you want the best chewy texture.
The sweetener is ⅓ cup honey or pure maple syrup. Agave can work in a pinch.
The binder is 2 large eggs. For vegan bars, use flax eggs made from 2 tablespoons ground flaxseed and 5 tablespoons water.
The recipe also uses 1 teaspoon baking powder and 1 teaspoon vanilla extract. Baking powder gives a little lift, while vanilla adds warm flavor.
Bake for 20 minutes, then check the center. If it jiggles like Jell-O, bake another 5 minutes.
Cool the bars in the pan for at least 10 minutes. Then lift them out and cool completely before slicing so they hold together.

- Splash of milk
- Extra handful of oats
- ½ cup dark chocolate chips
- ¼ cup chopped walnuts

Ingredient Notes
Ripe bananas are the heart of these bars. The bananas with lots of dark spots are best because they are softer and sweeter.
If your bananas are not ripe yet, place them in a paper bag overnight. This helps speed things up.
Rolled oats give the bars texture. They keep the bars chewy and sturdy enough to slice.
Instant oats can be used, but the texture will be softer and more muffin-like. Steel-cut oats should not be used because they need much longer cooking.
Honey adds gentle sweetness. Pure maple syrup gives a warmer flavor.
Agave can work if you are out of honey and maple syrup. Use it as a practical backup.
Eggs bind the bars so they hold together. They also help create a better structure.
Flax eggs can replace the eggs for a vegan version. Mix 2 tablespoons ground flaxseed with 5 tablespoons water, let it thicken for 5 minutes, then use it like eggs.
Baking powder gives the bars a little lift. It keeps them from becoming too heavy.
Vanilla extract gives warmth and makes the banana flavor feel fuller. Real vanilla makes a noticeable difference.
A splash of milk can help if the batter seems dry. Extra oats can help if the batter seems too wet.
Optional Swaps, Variations, Add-Ins, and Serving Ideas
Classic Banana Oatmeal Bars
Make the bars with ripe bananas, rolled oats, honey or maple syrup, eggs, baking powder, and vanilla. This gives the soft, chewy everyday version.
Cool completely before slicing. The bars hold together best once fully cooled.
Maple Banana Oatmeal Bars
Use pure maple syrup instead of honey. The flavor becomes deeper and cozier.
This version works beautifully with cinnamon. It tastes especially nice for breakfast.
Honey Banana Oatmeal Bars
Use honey for sweetness. Honey gives the bars a gentle floral note.
This is a classic choice. It pairs naturally with banana and oats.
Agave Banana Oatmeal Bars
Use agave in a pinch if you do not have honey or maple syrup. It sweetens the bars while keeping the method simple.
The flavor will be slightly different. The texture should still work.
Vegan Banana Oatmeal Bars
Use flax eggs instead of eggs. Mix 2 tablespoons ground flaxseed with 5 tablespoons water and let it thicken for 5 minutes.
The bars will be a little denser but still delicious. Let them cool completely before slicing.
Gluten-Free Banana Oatmeal Bars
Use certified gluten-free oats. Regular oats can be cross-contaminated, so check the label if gluten is a concern.
Everything else in the recipe is naturally gluten-free. Bake and cool as usual.
Chocolate Chip Banana Oatmeal Bars
Fold in ½ cup dark chocolate chips before baking. The chocolate melts into little sweet pockets.
For a bakery-style look, sprinkle a few extra chips on top before baking. Keep add-ins within about ¾ cup total.
Walnut Banana Oatmeal Bars
Add ¼ cup chopped walnuts for crunch. Toast them first for extra flavor if desired.
Walnuts pair well with bananas. They make the bars feel more hearty.
Pecan Banana Oatmeal Bars
Use ¼ cup chopped pecans. Pecans add a buttery crunch.
Toast them in a dry skillet for a few minutes if you want more flavor. Let them cool before mixing in.
Almond Banana Oatmeal Bars
Add ¼ cup chopped almonds. They bring a firmer crunch.
This variation works well with vanilla. Keep the pieces small.
Sunflower Seed Banana Oatmeal Bars
Use sunflower seeds instead of nuts. This is a good allergy-friendly crunch option.
The seeds add texture without changing the banana flavor too much. Fold them in gently.
Cinnamon Nutmeg Banana Oatmeal Bars
Add 1 teaspoon cinnamon and a pinch of nutmeg. This gives the bars a warm, cozy flavor.
The spices make the bars feel extra comforting. They work especially well with maple syrup.
Pumpkin Banana Oatmeal Bars
Swap half the honey for pumpkin purée. Reduce the mashed banana by ¼ cup so the bars do not become soggy.
This gives a fall-style twist. Add cinnamon and nutmeg if desired.
Dried Fruit Banana Oatmeal Bars
Add dried fruit for chewy sweetness. Keep the total add-ins around ¾ cup.
Chop larger fruit pieces if needed. This helps the bars slice more easily.
Coconut Banana Oatmeal Bars
Add coconut flakes for texture and flavor. Coconut pairs well with banana.
Do not add too much, or the bars may become loose. Keep total add-ins moderate.
Peanut Butter Drizzle Bars
Drizzle peanut butter over the cooled bars. This makes them feel richer and more satisfying.
Do the drizzle after slicing or after the slab cools. Let it set slightly before storing.
Protein Banana Oatmeal Bars
Add a scoop of protein powder if desired. Add a splash of milk to balance the batter.
Protein powder can make bars drier. Adjust with moisture as needed.
Sugar-Free Syrup Version
Swap honey for sugar-free syrup if that fits your needs. The flavor and texture may change slightly.
Watch the batter consistency. Add oats or milk only if needed.
Why This Recipe Works
This recipe works because ripe bananas provide sweetness, moisture, and structure. They help hold the oats together while giving the bars soft texture.
Rolled oats absorb moisture as the bars bake. They create chewiness without needing complicated ingredients.
Eggs help bind the mixture. This is what turns the batter into sliceable bars instead of loose oatmeal.
Honey or maple syrup adds sweetness and helps the bars taste balanced. The amount is enough to make the bars enjoyable without overpowering the banana.
Baking powder gives a little lift. This keeps the bars from feeling too dense.
Vanilla adds warmth. It makes the banana and oats taste more rounded.
The 8×8-inch pan gives the bars the right thickness. They bake evenly and slice into sturdy squares.
Cooling matters because the bars firm as they rest. Cutting too soon can make them crumble.
Directions
Step 1: Preheat the Oven
Preheat the oven to 350°F (175°C). Let it fully heat before baking.
A steady oven temperature helps the bars bake evenly. This is especially important for the center.
Step 2: Prepare the Pan
Line an 8×8-inch baking pan with parchment paper. Leave a little overhang on the sides.
The overhang lets you lift the cooled bars out easily. This makes slicing cleaner.
Step 3: Grease if Not Using Parchment
If you do not have parchment paper, grease the pan with butter or coconut oil. Coat the bottom and sides.
This prevents sticking. Do not skip this step.
Step 4: Mash the Bananas
Place 3 ripe bananas in a large bowl. Mash with a fork until the mixture is mostly smooth but still a little lumpy.
A few banana chunks are fine. They add texture and make the bars feel homemade.
Step 5: Add Eggs, Sweetener, and Vanilla
Whisk the 2 large eggs into the mashed bananas. Add ⅓ cup honey or pure maple syrup and 1 teaspoon vanilla extract.
Mix until combined. The mixture may look loose, but that is normal.
Step 6: Add the Baking Powder
Sprinkle in 1 teaspoon baking powder. Stir until evenly mixed.
This helps the bars rise slightly. Make sure there are no clumps of baking powder.
Step 7: Fold in the Oats
Add 2 cups rolled oats. Fold them in gently with a spatula or spoon.
Do not overmix. Gentle folding keeps the bars from becoming too dense.
Step 8: Check the Batter Texture
The batter should be thick and sticky. If it seems too dry, add a splash of milk.
If it seems too wet, add another handful of oats. Banana size can vary, so small adjustments are normal.
Step 9: Add Optional Mix-Ins
Fold in add-ins if using, such as dark chocolate chips, chopped nuts, sunflower seeds, dried fruit, coconut flakes, cinnamon, or nutmeg. Keep total add-ins around ¾ cup.
Too many add-ins can make the bars fall apart. Mix gently.
Step 10: Spread the Batter
Pour the batter into the prepared 8×8-inch pan. Use a spatula to spread it evenly.
Smooth the top so the bars bake evenly. Press lightly if needed.
Step 11: Bake the Bars
Bake for 20 minutes. The edges should look golden.
The center should spring back slightly when tapped. If it jiggles like Jell-O, bake for another 5 minutes.
Step 12: Avoid Overbaking
Watch the bars closely near the end. Overbaking can dry them out.
Remove them when the edges are just golden and the center barely springs back. They continue to firm as they cool.
Step 13: Cool in the Pan
Let the bars cool in the pan for at least 10 minutes. This helps them firm enough to lift.
Do not slice right away. Warm bars crumble more easily.
Step 14: Lift Out of the Pan
Use the parchment overhang to lift the bars onto a rack. If the pan was greased, loosen the edges gently first.
Move carefully. The bars are still setting.
Step 15: Cool Completely
Let the bars cool completely before slicing. This is the key to clean squares.
Fully cooled bars hold together much better. Patience makes a real difference.
Step 16: Slice Into Bars
Cut the cooled slab into squares or rectangles. Use a sharp knife.
Wipe the knife between cuts if needed. This gives neater edges.
Step 17: Store for the Week
Place cooled bars in an airtight container. Store at room temperature for up to 3 days.
If your kitchen is humid, tuck a paper towel into the container to absorb moisture. This helps protect the texture.
Step 18: Freeze for Later
Wrap individual bars in parchment and place them in a zip-top bag. Freeze for up to 3 months.
Thaw on the counter for about 1 hour or microwave for 15 seconds. This makes them easy grab-and-go snacks.

Serving Ideas
Serve Delicious Banana Oatmeal Bars at room temperature for the best texture. They will be soft but sturdy enough to pack or hold.
They are also delicious warm, especially if you like a softer bite. Just know they hold together better after cooling.
Pack them in lunchboxes for a simple snack. The bars travel well once fully cooled.
Serve them for breakfast on busy mornings. They are easy to grab when there is no time for a sit-down meal.
Enjoy them after a workout when you want something quick and homemade. The oats and bananas make them satisfying.
Pair them with coffee or tea for a calm afternoon snack. The banana and vanilla flavors feel cozy.
Turn frozen bars into an “ice cream” sandwich base by adding vanilla between two halves. This makes a fun dessert.
Drizzle with peanut butter for a richer snack. Add the drizzle after the bars are cool.
Storage
Store cooled banana oatmeal bars in an airtight container at room temperature. They keep for up to 3 days.
Make sure the bars are fully cooled before storing. Warm bars can create steam and become too soft.
If your kitchen is humid, place a paper towel in the container. It helps absorb extra moisture.
Keep the container sealed. This prevents the bars from drying out.
Do not stack warm bars. They may stick together or crumble.
If adding a peanut butter drizzle, let it set before storing. This keeps the bars neater.
Check texture before serving leftovers. If they feel very soft, let them sit uncovered briefly.
Freezing
These bars freeze very well. Wrap individual bars in parchment before placing them in a zip-top bag.
Freeze for up to 3 months. Individual wrapping makes it easy to grab one at a time.
To thaw, leave a bar on the counter for about 1 hour. It will soften naturally.
For a faster option, microwave for 15 seconds. This gives quick snack satisfaction.
Freezing is perfect for meal prep. You can bake once and save snacks for busy mornings.
Label the bag if desired. This helps you remember when you made them.
Do not freeze before the bars cool completely. Cooling first protects texture.
Make-Ahead
These bars are ideal for making ahead. Bake a batch on Sunday and enjoy them through the week.
They taste even better the next day. The oats settle, and the banana flavor becomes more rounded.
You can also freeze the bars for longer storage. Wrap individually for easy future snacks.
If making for lunchboxes, slice only after fully cooled. This helps the bars stay neat.
Add-ins can be changed each time you bake. Keep the base recipe the same and vary the flavor.
For a morning shortcut, mash the bananas and measure the dry ingredients the night before. Mix and bake when ready.
Make sure the finished bars are stored airtight. This keeps them soft and chewy.
Helpful Notes for Best Results
Use very ripe bananas. Spotted bananas are sweeter and easier to mash.
Do not use instant oats if you want chewy texture. Rolled oats work best.
Do not use steel-cut oats. They require serious cooking time and will not soften properly here.
Fold the oats gently. Overmixing can make the bars dense.
Cool completely before slicing. This prevents crumbling.
If the bars are crumbly, add an extra banana next time or 1 tablespoon nut butter. This adds moisture and helps bind.
If the bars are too dense, avoid overmixing the batter. Fold the oats in gently.
If the bars are mushy, drain excess liquid from mashed bananas next time or add an extra ¼ cup oats. Very overripe bananas can sometimes be too wet.
Variations
Classic Banana Oatmeal Bars
Use ripe bananas, rolled oats, honey or maple syrup, eggs, baking powder, and vanilla. This gives the simple soft and chewy version.
Bake until the edges are golden and the center springs back slightly. Cool completely before slicing.
Chocolate Chip Banana Oatmeal Bars
Add ½ cup dark chocolate chips. The chocolate melts into sweet pockets.
Sprinkle a few extra chips on top before baking if desired. This makes the bars look more bakery-style.
Walnut Banana Oatmeal Bars
Add ¼ cup chopped walnuts. They bring crunch and a nutty flavor.
Toast them first if you want more flavor. Let them cool before adding.
Pecan Banana Oatmeal Bars
Use ¼ cup chopped pecans. Pecans make the bars taste warmer and richer.
They pair especially well with maple syrup. Keep the pieces small.
Almond Banana Oatmeal Bars
Add ¼ cup chopped almonds. This gives firmer crunch.
Almonds work nicely with vanilla. Fold them in gently.
Sunflower Seed Banana Bars
Use sunflower seeds instead of nuts. This adds crunch without tree nuts.
This is a good option for nut-free snacking. Keep the amount modest.
Cinnamon Banana Oatmeal Bars
Add 1 teaspoon cinnamon. This gives the bars a cozy flavor.
Cinnamon works with honey or maple syrup. It also pairs well with nuts.
Cinnamon Nutmeg Banana Bars
Add 1 teaspoon cinnamon and a pinch of nutmeg. This makes the bars taste warm and comforting.
Use only a pinch of nutmeg. It should not overpower the banana.
Pumpkin Banana Oatmeal Bars
Swap half the honey for pumpkin purée. Reduce the mashed banana by ¼ cup so the bars do not get soggy.
This gives a fall-themed twist. Cinnamon and nutmeg fit well here.
Dried Fruit Banana Bars
Add dried fruit for chewy sweetness. Keep total add-ins around ¾ cup.
Chop larger pieces. This helps the bars hold together.
Coconut Banana Oatmeal Bars
Add coconut flakes. Coconut brings texture and a slightly tropical flavor.
Do not add too much. Too many dry add-ins can loosen the bars.
Peanut Butter Drizzle Bars
Drizzle peanut butter over the cooled bars. This adds richness.
You can also add 1 tablespoon nut butter to the batter next time if your bars tend to crumble. It adds moisture.
Vegan Banana Oatmeal Bars
Use flax eggs instead of eggs. Mix 2 tablespoons ground flaxseed with 5 tablespoons water and let it thicken.
The bars will be denser. Let them cool fully before slicing.
Gluten-Free Banana Oatmeal Bars
Use certified gluten-free oats. Check the label carefully.
The rest of the recipe is naturally gluten-free. Bake as directed.
Protein Banana Oatmeal Bars
Add a scoop of protein powder. Add a splash of milk to balance it.
Protein powder can absorb moisture. Watch the batter texture.
Troubleshooting
The Bars Are Crumbly
They may need more moisture. Add an extra banana next time or 1 tablespoon nut butter.
Also make sure the bars cool completely before slicing. Warm bars crumble more easily.
The Bars Are Too Dense
The batter may have been overmixed. Fold the oats in gently.
Do not stir aggressively after adding oats. Gentle mixing protects the texture.
The Bars Are Mushy
The bananas may have been extremely overripe and watery. Drain excess liquid from the mashed bananas next time.
You can also add an extra ¼ cup oats. This helps soak up moisture.
The Batter Looks Too Dry
Add a splash of milk. Stir gently and check again.
Banana size varies, so small adjustments are normal. The batter should be thick and sticky.
The Batter Looks Too Wet
Add another handful of oats. Fold gently.
Let the mixture sit briefly if needed so the oats can absorb moisture. Then bake.
The Bars Stuck to the Pan
Use parchment with overhang next time. It makes lifting the bars easy.
If you do not have parchment, grease the pan with butter or coconut oil. Pan prep matters.
The Bars Fell Apart When Cut
They may not have cooled completely. Let them cool fully before slicing.
Use a sharp knife. Cut cleanly without dragging too much.
The Edges Are Dry
The bars may have baked too long. Pull them when the edges are golden and the center barely springs back.
Check at 20 minutes. Add only 5 minutes if needed.
The Center Is Underdone
If the center jiggles like Jell-O, bake another 5 minutes. The center should spring back slightly.
Let the bars cool fully after baking. They firm as they cool.
The Bars Need More Flavor
Add cinnamon, nutmeg, vanilla, chocolate chips, nuts, coconut, or dried fruit. Keep total add-ins around ¾ cup.
Peanut butter drizzle can also add flavor. Add it after cooling.

Why This Recipe Works So Well
Delicious Banana Oatmeal Bars work because the bananas act as both flavor and moisture. They sweeten the bars naturally while helping bind the oats.
Rolled oats give structure. They absorb the wet ingredients and create a chewy texture.
Eggs hold the bars together. Flax eggs can also work for a denser vegan version.
Honey or maple syrup adds just enough sweetness. It also helps the bars taste more finished.
Baking powder gives the bars a little lift. Without it, they can feel heavier.
Vanilla brings warmth. It makes the simple ingredients taste more rounded.
The 8×8-inch pan creates bars that are not too thin and not too thick. They bake evenly in about 20 minutes, with extra time only if needed.
Cooling is essential because the bars firm as they rest. The texture improves after they are fully cool.
Most of all, these bars work because they are practical. They use basic ingredients, adapt to what you have, freeze well, and fit into real mornings when everyone needs something quick.
Final Thoughts
Delicious Banana Oatmeal Bars are made with ripe bananas, rolled oats, honey or maple syrup, eggs, baking powder, and vanilla, then baked into soft, chewy squares that are perfect for breakfast, snacks, lunchboxes, and meal prep. The batter comes together in one bowl, bakes in an 8×8-inch pan, and slices best after cooling completely.
Keep them simple or add dark chocolate chips, nuts, cinnamon, nutmeg, dried fruit, coconut flakes, sunflower seeds, pumpkin purée, or a peanut butter drizzle. With their 3-day room-temperature storage, 3-month freezer option, flexible gluten-free and vegan directions, and easy grab-and-go texture, these banana oatmeal bars are a dependable homemade snack for busy days and cozy cravings alike.
Banana Oatmeal Bars

Soft, simple, naturally sweet, and made with just a short list of ingredients, these Banana Oatmeal Bars combine ripe bananas, rolled oats, honey or pure maple syrup, eggs, baking powder, and vanilla extract. They make an easy American-style snack bar with a hearty oat texture and sweet banana flavor.
Recipe Details
- Prep Time: 10 minutes
- Cook Time: 25 minutes
- Total Time: 35 minutes
- Course: Snack
- Cuisine: American
- Servings: 12 bars
Ingredients
For the Banana Oatmeal Bars
- 1 teaspoon vanilla extract
- 1 teaspoon baking powder
- 2 large eggs
- ⅓ cup honey or pure maple syrup
- 2 cups rolled oats
- 3 ripe bananas (about 1 ½ cups mashed)
Instructions
Step 1: Mash the Bananas
Mash the ripe bananas until they measure about 1 ½ cups. The bananas should be soft enough to blend easily with the rest of the ingredients.
This mashed banana base gives the bars their sweetness and moisture. Make sure there are no large chunks before moving on.
Step 2: Mix the Wet Ingredients
Combine the mashed bananas with the honey or pure maple syrup, large eggs, and vanilla extract. Stir until the mixture is smooth and evenly blended.
Use either honey or pure maple syrup as listed. Both options add sweetness while keeping the bars simple.
Step 3: Add the Oats and Baking Powder
Stir in the rolled oats and baking powder. Mix until the oats are fully coated with the banana mixture.
The batter should look thick and oat-filled. Make sure the baking powder is evenly distributed so the bars bake consistently.
Step 4: Prepare for Baking
Spread the mixture evenly into a baking pan. The recipe does not provide a specific pan size, so no exact pan measurement is added here.
Smooth the top so the bars bake into an even layer. Keep the thickness as even as possible for cleaner slicing.
Step 5: Bake the Bars
Bake for the listed cook time of 25 minutes. The recipe does not provide a baking temperature, so no exact oven setting is added here.
The bars should bake until set. Use the texture as the main doneness cue, since no additional visual cue is provided.
Step 6: Cool and Slice
Let the bars cool before slicing. Cut into 12 bars once they are firm enough to portion cleanly.
Cooling helps the oat mixture settle and hold its shape. Serve as a snack once sliced.
Notes
- Store in an airtight container for up to 3 days.
Serving Suggestions
Serve Banana Oatmeal Bars once they have cooled and set enough to slice. The ripe bananas, rolled oats, honey or pure maple syrup, eggs, baking powder, and vanilla create a simple snack bar with a soft oat texture.
These bars work well as an easy snack for busy days, lunch boxes, or simple make-ahead treats. Since the recipe makes 12 bars, they are easy to portion and store.
Use ripe bananas for the best natural sweetness. The recipe gives the mashed banana amount as about 1 ½ cups, which helps keep the texture consistent.
Storage
How to Store
Store the bars in an airtight container for up to 3 days. Keep the container sealed so the bars stay fresh.
Banana Tip
Use 3 ripe bananas, about 1 ½ cups mashed. Mash them well before mixing with the other ingredients.
Oat Tip
Use 2 cups rolled oats as listed. Stir them in until they are fully coated with the banana mixture.
Sweetener Tip
Use ⅓ cup honey or pure maple syrup. Either option works with the bananas and oats.
Baking Note
The recipe provides a cook time of 25 minutes but does not include a baking temperature or pan size. For accuracy, no oven temperature or pan measurement is added.
Slicing Tip
Let the bars cool before cutting into 12 pieces. This helps them hold together more neatly.
