Marshmallow Chocolate Cookies are the kind of treat that makes a kitchen feel instantly happier. They are rich with cocoa, soft in the center, dotted with semi-sweet chocolate chips, and filled with mini marshmallows that create a sweet, chewy, cozy bite.
I love cookies that feel playful without being complicated. These have the deep comfort of chocolate and the light, fluffy sweetness of marshmallows, all wrapped into a simple dough that comes together quickly.
There is something especially comforting about warm chocolate cookies cooling on a baking sheet. The smell fills the room, the marshmallows soften into little pockets, and everyone suddenly has a reason to linger near the kitchen.
These cookies are easy enough for beginner bakers and quick enough for last-minute cravings. With just 15 minutes of prep and 10 minutes of baking, you can have a batch ready in about 25 minutes.
They are also wonderful for sharing. Bring them to a gathering, bake them for a holiday tray, serve them warm with milk, or turn them into a dessert with vanilla ice cream on top.

Recipe Details
Prep Time: 15 minutes
Cook Time: 10 minutes
Total Time: 25 minutes
Servings: 24 cookies
The cookies bake at 350°F (175°C). The dough is dropped onto a lined baking sheet with about 2 inches of space between each cookie.
The dry ingredients include 1 ¾ cups all-purpose flour, ½ cup unsweetened cocoa powder, 1 teaspoon baking soda, and ¼ teaspoon salt. These should be whisked together to remove lumps.
The wet base uses ½ cup softened unsalted butter, ¾ cup granulated sugar, ½ cup packed light brown sugar, 1 large egg, and 1 teaspoon vanilla extract. The butter should be softened for the best creamy texture.
The mix-ins are ½ cup semi-sweet chocolate chips and 1 cup mini marshmallows. For extra gooeyness, ⅓ cup marshmallow fluff can be folded in optionally.
The cookies bake for about 10 minutes. The edges should look set while the centers remain soft.
After baking, the cookies cool on the baking sheet for about 5 minutes before being transferred to a wire rack. Cooling completely helps them achieve the best chewy texture.
Ingredients
Dry Ingredients
1 ¾ cups all-purpose flour
½ cup unsweetened cocoa powder
1 teaspoon baking soda
¼ teaspoon salt
Cookie Dough Base
½ cup unsalted butter, softened
¾ cup granulated sugar
½ cup packed light brown sugar
1 large egg
1 teaspoon vanilla extract
Chocolate Marshmallow Mix-Ins
½ cup semi-sweet chocolate chips
1 cup mini marshmallows
⅓ cup marshmallow fluff, optional
Ingredient Notes
All-purpose flour gives the cookies their structure. It helps the dough hold the chocolate chips and marshmallows.
Unsweetened cocoa powder gives these cookies their rich chocolate flavor. A high-quality cocoa powder can make the chocolate taste deeper.
Baking soda helps the cookies bake properly. It supports the spread and texture.
Salt balances the sweetness. Even a small amount makes the chocolate flavor taste stronger and more complete.
Unsalted butter should be softened. Room temperature butter creams smoothly with the sugars and helps create the right cookie texture.
Granulated sugar sweetens the dough and helps with the cookie structure. Light brown sugar adds moisture and a deeper sweetness.
The egg helps bind the dough. Vanilla extract enhances the overall flavor, and pure vanilla gives a richer taste.
Semi-sweet chocolate chips bring extra chocolate pockets. Mini marshmallows add gooey sweetness and a soft, chewy contrast.
Marshmallow fluff is optional. It adds more marshmallow flavor and makes the texture even more delightful.
Optional Swaps, Variations, Add-Ins, and Serving Ideas
Cinnamon Chocolate Marshmallow Cookies
Add a pinch of cinnamon to the dough. This gives the cookies a warm, spiced flavor.
The cinnamon should stay subtle. It adds coziness without covering the chocolate.
Peanut Butter Chip Cookies
Use peanut butter chips instead of chocolate chips. This creates a nutty twist.
The peanut butter flavor works well with cocoa and marshmallow. It turns the cookie into a richer, candy-like treat.
Peppermint Marshmallow Cookies
Incorporate crushed peppermint candies during the holidays. This gives the cookies a festive touch.
Peppermint brings brightness to the rich chocolate dough. It is a fun option for seasonal cookie trays.
Gluten-Free Marshmallow Chocolate Cookies
Substitute the all-purpose flour with a gluten-free blend. This creates a gluten-free direction for the recipe.
The texture may vary depending on the blend. Follow the same baking cues and avoid overmixing.
Flavored Marshmallow Cookies
Experiment with different flavored marshmallows, such as coconut or strawberry. This gives the cookies a unique twist.
Flavored marshmallows can change both taste and appearance. Use them when you want something playful.
Dairy-Free Direction
Use coconut oil or plant-based butter instead of butter. This creates a dairy-free option.
The texture may change slightly. Choose a substitute that works well in cookies.
Vegan Direction
Use an egg replacer such as flaxseed meal or applesauce. Pair it with coconut oil or plant-based butter.
The result will not be exactly the same, but it can still make a sweet chocolate marshmallow-style cookie. Follow the same visual doneness cues.
Nutty Chocolate Marshmallow Cookies
Mix in chopped walnuts or pecans for added texture. The nuts give the cookies a crunchy contrast.
Walnuts bring a classic chocolate pairing. Pecans add a slightly buttery crunch.
Less Sweet Cookies
Reduce the sugar by ¼ cup if you prefer a less sweet cookie. The texture should still hold.
This is helpful if you want the cocoa flavor to stand out more. Keep the rest of the method the same.
Why These Marshmallow Chocolate Cookies Work
These cookies work because the dough balances rich chocolate with sweet, soft marshmallows. The cocoa powder gives depth, while the mini marshmallows create little chewy pockets.
The butter and sugars are creamed together to build the cookie base. This helps the dough become light enough to bake into soft cookies.
The brown sugar adds moisture. That helps the cookies stay chewy instead of dry.
The chocolate chips give extra richness. They make each cookie taste more indulgent.
The marshmallow fluff, if used, adds more marshmallow flavor and a slightly gooier texture. It blends into the dough and makes the cookie feel even more special.
The short bake time keeps the centers soft. The cookies finish setting as they cool on the baking sheet.
Directions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This gives the cookies a consistent baking temperature.
Let the oven heat fully before the baking sheet goes in. Cookies bake quickly, so starting with the right temperature matters.
While the oven warms, prepare the baking sheet and gather the ingredients. This keeps the process smooth once the dough comes together.
Step 2: Prepare the Baking Sheet
Line a baking sheet with parchment paper. This helps prevent the cookies from sticking.
Using a lined baking sheet also makes cleanup easier. Marshmallows can get sticky as they bake, so parchment is helpful.
Set the prepared baking sheet aside. You will scoop the dough onto it once the mix-ins are folded in.
Step 3: Measure the Flour
Add 1 ¾ cups all-purpose flour to a mixing bowl. Measure carefully so the dough does not become too dry.
Too much flour can make cookies heavy. A proper amount keeps them soft and chewy.
This bowl will hold the dry ingredients. Choose one with enough room for whisking.
Step 4: Add the Cocoa Powder
Add ½ cup unsweetened cocoa powder to the flour. Cocoa powder can clump, so it needs to be whisked well.
A high-quality cocoa powder can create a richer chocolate flavor. Use what you enjoy for baking.
Do not leave lumps in the dry mixture if you can help it. Lumps can create uneven chocolate pockets.
Step 5: Add Baking Soda and Salt
Add 1 teaspoon baking soda and ¼ teaspoon salt to the bowl. These small ingredients matter.
The baking soda helps the cookies bake properly. The salt balances sweetness and deepens the chocolate flavor.
Whisk the dry ingredients together until evenly combined. Set the bowl aside when finished.
Step 6: Soften the Butter
Measure ½ cup unsalted butter and make sure it is softened. Let it sit at room temperature for about 10 minutes if needed for easy mixing.
Softened butter should be easy to press but not melted. This texture helps it cream with the sugars.
Cold butter can affect the cookie texture. Soft butter is easier to blend into a smooth base.
Step 7: Add the Sugars to the Butter
Place the softened butter in another bowl. Add ¾ cup granulated sugar and ½ cup packed light brown sugar.
Pack the brown sugar firmly when measuring. This gives the dough the right sweetness and moisture.
The two sugars work together. Granulated sugar brings structure, while brown sugar helps create chewiness.
Step 8: Cream the Butter and Sugars
Use an electric mixer or whisk to cream the butter and sugars together. Mix until the mixture looks light and fluffy.
This step helps create a smoother dough. It also begins building the soft cookie texture.
Scrape the bowl if needed. You want the butter and sugars evenly blended with no large clumps.
Step 9: Add the Egg
Crack in 1 large egg. Mix until fully combined.
The egg binds the cookie dough. It also helps the cookies hold together after baking.
Mix until the dough base looks smooth. There should not be visible streaks of egg.
Step 10: Add the Vanilla
Pour in 1 teaspoon vanilla extract. Mix again until it disappears into the butter-sugar mixture.
Vanilla enhances the chocolate flavor. Pure vanilla gives the best taste if you have it.
At this point, the wet mixture should look smooth and creamy. It is ready for the dry ingredients.
Step 11: Add the Dry Mixture Gradually
Gradually add the flour, cocoa, baking soda, and salt mixture to the wet mixture. Stir as you add.
Adding the dry mixture in portions makes it easier to combine. It also reduces the risk of overmixing.
Use gentle mixing once the flour begins to disappear. The goal is a soft dough, not a beaten batter.
Step 12: Mix Just Until Combined
Stir until the dry ingredients are just incorporated. Do not overmix.
Overmixing can lead to tough cookies. Stop once the dough looks evenly chocolatey.
The dough should be thick and soft. It should be ready to hold the chocolate chips and marshmallows.
Step 13: Fold in the Chocolate Chips
Add ½ cup semi-sweet chocolate chips. Fold them gently into the dough.
The chocolate chips should be spread throughout. They add extra richness to each cookie.
Use a spatula or spoon for folding. This keeps the dough from being worked too much.
Step 14: Fold in the Mini Marshmallows
Add 1 cup mini marshmallows. Fold them into the dough gently.
Fresh mini marshmallows give the best gooey texture. Try to distribute them evenly through the dough.
Do not crush the marshmallows while mixing. Gentle folding keeps them intact.
Step 15: Add Marshmallow Fluff if Using
If using marshmallow fluff, fold in ⅓ cup at this stage. It adds extra marshmallow flavor and gooey texture.
Fold carefully because fluff can streak through the dough. A few ribbons are fine.
The dough may look slightly messy. That is normal for marshmallow cookies.
Step 16: Scoop the Dough
Use a spoon or cookie scoop to drop generous spoonfuls of dough onto the lined baking sheet. Keep the portions similar in size.
Space the cookies about 2 inches apart. This gives them room to spread.
Do not crowd the baking sheet. Crowding can make the cookies merge together.
Step 17: Bake the Cookies
Bake in the preheated oven for about 10 minutes. The edges should look set while the centers remain soft.
Do not wait for the centers to look fully firm. They will continue to set as the cookies cool.
The kitchen should smell deeply chocolatey as they bake. That warm scent is part of the joy.
Step 18: Cool on the Baking Sheet
Remove the baking sheet from the oven. Let the cookies cool on the baking sheet for about 5 minutes.
This short rest helps the soft centers finish setting. It also makes the cookies easier to move.
Do not rush them off the sheet while they are too hot. Warm cookies can break easily.
Step 19: Transfer to a Wire Rack
After 5 minutes, transfer the cookies to a wire rack. Let them cool completely.
Cooling on a rack helps the cookies finish with the right chewy texture. Air can circulate around them.
The marshmallows and chocolate will firm slightly as the cookies cool. The wait is worth it.
Step 20: Serve and Enjoy
Serve the cookies once they have cooled enough to handle. They are delicious warm, soft, and chewy.
For the best chewy texture, let them cool completely. The centers settle and become more satisfying.
Enjoy them plain, with milk, with coffee, or with a scoop of vanilla ice cream. These cookies are made for sweet, cozy moments.

Serving Ideas
Serve Marshmallow Chocolate Cookies warm when you want the marshmallows and chocolate to feel extra soft. They are especially comforting shortly after baking.
A glass of milk is a classic pairing. It balances the rich chocolate flavor.
A cup of coffee also works beautifully. The coffee makes the chocolate taste even deeper.
For an indulgent dessert, add a scoop of vanilla ice cream on top. The warm cookie and cold ice cream make a melty treat.
These cookies are lovely for holidays and gatherings. Their chocolate-marshmallow combination feels festive and fun.
They are also perfect for sharing with family or friends. A plate of these cookies can make even a rainy afternoon feel special.
Storage
Store the cookies in an airtight container at room temperature. They will keep for up to 1 week.
Let them cool completely before storing. Warm cookies can create steam, which changes the texture.
Keep the container sealed between servings. This helps maintain freshness.
If the cookies are stacked, handle them gently. The marshmallows can make the surface a little sticky.
Reheating
To bring back a fresh-baked taste, microwave a cookie for a few seconds. This warms the chocolate and softens the marshmallow.
Do not overheat. The cookie can become too soft if microwaved too long.
A brief warm-up is enough. Let it sit for a moment before eating because the chocolate and marshmallow can become hot.
These cookies are also wonderful at room temperature. Reheating is optional.
Freezing
These cookies can be frozen after they are fully cooled. Place them in an airtight container or freezer-safe bag.
Freeze for up to 3 months. This makes them useful for make-ahead treats.
Thaw at room temperature before enjoying. You can also microwave them for a few seconds to warm them up.
Make sure the cookies are cooled before freezing. This protects the texture and prevents extra moisture.
Make-Ahead
The dough can be made ahead of time. Refrigerate it for up to 3 days before baking.
Before scooping and baking, let the dough sit at room temperature for about 10 minutes. This makes it easier to portion.
Bake fresh cookies whenever you need a sweet treat. The warm chocolate and marshmallow aroma makes them feel freshly special.
Make-ahead dough is helpful for holidays, gatherings, or busy weeks. You can bake only what you need.
Common Mistakes
Overmixing the Dough
Overmixing can lead to tough cookies. Mix just until the dry ingredients are combined.
Once the flour and cocoa disappear into the dough, stop. Gentle mixing keeps the cookies soft.
Using Cold Butter
Cold butter does not cream properly with the sugars. This can affect the final texture.
Use softened butter at room temperature. It should blend smoothly with the granulated sugar and brown sugar.
Baking on an Unlined Sheet
An unlined baking sheet may cause the cookies to stick. Marshmallows can melt and cling to the pan.
Use parchment paper on the baking sheet. This makes removal much easier.
Crowding the Cookies
Cookies need room to spread. If they are too close together, they can merge.
Space them about 2 inches apart. Bake in batches if needed.
Overbaking
Overbaking can make the cookies dry. Bake until the edges are set and the centers are still soft.
The cookies continue setting on the baking sheet. Pulling them at the right time keeps them chewy.
Helpful Notes for Best Results
Use fresh mini marshmallows for extra gooeyness. Stale marshmallows may not give the same texture.
Do not overmix after adding the dry ingredients. This keeps the cookies soft.
Use parchment paper to line the baking sheet. It helps prevent sticking.
Let the cookies cool on the baking sheet for 5 minutes before moving them. This helps them set.
For dairy-free options, use coconut oil or plant-based butter. The texture may change slightly.
For a vegan direction, use flaxseed meal or applesauce as an egg replacer. Pair that with a dairy-free butter substitute.
For added texture, mix in chopped walnuts or pecans. They add crunch to the soft cookies.
If you prefer less sweetness, reduce the sugar by ¼ cup. The texture should still hold.
Variations
Cinnamon Marshmallow Chocolate Cookies
Add a pinch of cinnamon to the dough. It gives the cookies a soft spiced warmth.
This is a simple change. The chocolate and marshmallow still stay at the center.
Peanut Butter Chip Marshmallow Cookies
Use peanut butter chips instead of chocolate chips. This gives the cookies a nutty twist.
The peanut butter flavor pairs well with cocoa. It makes the cookies taste richer.
Peppermint Marshmallow Chocolate Cookies
Add crushed peppermint candies during the holidays. This creates a festive cookie.
The peppermint brightens the chocolate flavor. It is perfect for seasonal gatherings.
Gluten-Free Marshmallow Cookies
Use a gluten-free flour blend instead of all-purpose flour. Keep the same mixing method.
The texture may vary by blend. Bake until the edges are set and the centers are soft.
Coconut Marshmallow Cookies
Use coconut-flavored marshmallows for a unique twist. They give the cookies a different sweet note.
This variation feels playful. It is a fun way to change the flavor without changing the method.
Strawberry Marshmallow Cookies
Use strawberry-flavored marshmallows. They bring a fruity marshmallow flavor.
The strawberry note works with the chocolate base. It makes the cookies colorful and different.
Dairy-Free Marshmallow Chocolate Cookies
Use coconut oil or plant-based butter instead of butter. Choose a substitute that works well for baking.
The cookies may have a different texture. Follow the same visual cues for doneness.
Vegan Marshmallow Chocolate Cookies
Use an egg replacer like flaxseed meal or applesauce. Use coconut oil or plant-based butter for the fat.
The texture will change, but the cookies can still be sweet and satisfying. Use the same baking cues.
Walnut Marshmallow Chocolate Cookies
Add chopped walnuts. They give the cookies crunch.
Walnuts balance the soft marshmallows. They make each bite more textured.
Pecan Marshmallow Chocolate Cookies
Add chopped pecans. Pecans bring a gentle, buttery crunch.
This variation feels cozy and rich. It works well with chocolate and marshmallow.
Troubleshooting
Why Are My Cookies Tough?
The dough may have been overmixed. Mix just until the dry ingredients are combined.
Too much mixing can make cookies firmer than intended. Gentle stirring protects the soft texture.
Why Did My Cookies Stick to the Pan?
The baking sheet may not have been lined. Use parchment paper to prevent sticking.
Melted marshmallow can cling to an unlined pan. A lined sheet makes removal easier.
Why Did My Cookies Spread Into Each Other?
They may have been placed too close together. Space the dough about 2 inches apart.
Bake in more than one batch if needed. Room to spread helps each cookie keep its shape.
Why Are My Centers Too Soft?
The centers should be soft when the cookies come out. They continue to set as they cool.
If they are wet and raw, bake a little longer next time. Look for set edges and soft centers.
Why Are My Cookies Dry?
They may have baked too long. Bake for about 10 minutes and watch the edges.
The centers should remain soft. This keeps the cookies chewy after cooling.

Why This Recipe Works So Well
Marshmallow Chocolate Cookies work because the cookie base is rich, soft, and chocolatey, while the marshmallows add sweetness and chew. Every bite has a mix of cocoa, chocolate chips, and fluffy marshmallow.
The butter and sugars build the soft structure. Creaming them together helps the dough become light and smooth.
The brown sugar brings moisture. That helps the cookies stay chewy after baking.
The cocoa powder gives the cookies their deep flavor. Chocolate chips add even more richness.
The mini marshmallows make the cookies fun and memorable. Marshmallow fluff, if used, adds another layer of marshmallow flavor.
