Chocolate Marshmallow Swirl Cookies Recipe

They’re a nostalgic treat with a modern twist, oozing with decadence and childhood campfire joy!

Ingredients You’ll Need

The secret to unforgettable Chocolate Marshmallow Swirl Cookies is a handful of essential ingredients that each bring something special: richness, chewiness, and that signature swirl. While simple, every component works hard to deliver a cookie that’s so much more than the sum of its parts.

• All-purpose flour: Provides structure, ensuring your cookies are thick and chewy—not cakey or flat.
• Unsweetened cocoa powder: Delivers deep, chocolatey flavor without extra sweetness for a true chocolate punch.
• Baking soda: Allows the cookies to spread just the right amount, resulting in crisp edges and soft centers.
• Salt: A tiny pinch makes the chocolate flavor pop and keeps the sweetness in balance.
• Unsalted butter (room temperature): Gives richness while helping create a perfectly tender crumb. Always start with softened butter!
• Granulated sugar: Adds sweetness and helps achieve those beautifully crisp edges.
• Large eggs (room temperature): Bind everything together and add moisture for a soft, irresistible bite.
• Vanilla extract: Rounds out the flavors with aromatic warmth. Don’t skip the real stuff if you can!
• Marshmallow fluff: The real superstar—this swirls into the dough to create pockets of gooey, sticky-sweet magic in every bite.

Variations

One of the best things about Chocolate Marshmallow Swirl Cookies is how adaptable they are. Don’t be shy about riffing on the classic—these cookies are deliciously open to twists for different flavors, textures, or dietary needs.

• Peanut Butter Swirl: Replace a portion of the marshmallow fluff with creamy peanut butter for a decadent, nutty upgrade.
• Gluten-Free Version: Swap the all-purpose flour for a trusted 1:1 gluten-free baking blend for cookies everyone can enjoy.
• Choco-Mint Burst: Add a splash of peppermint extract to the dough and a sprinkle of crushed peppermint candies on top for a holiday-ready treat.
• Rocky Road Style: Fold in some chopped toasted walnuts or almonds and mini chocolate chips to echo that classic ice cream flavor.

How to Make Chocolate Marshmallow Swirl Cookies

Step 1: Whisk Dry Ingredients

Start by whisking together your flour, cocoa powder, baking soda, and salt in a medium bowl. This helps distribute the cocoa evenly (no big bitter clumps!) and gives your cookies a homogenous, luscious chocolate crumb.

Step 2: Cream Butter and Sugar

Using a stand or hand mixer, beat your softened butter and granulated sugar for 3–4 minutes, until it looks pale and fluffy. This step is crucial—the air you whip in here means a lighter texture and perfect bite once baked.

Step 3: Add Eggs and Vanilla

Add the eggs one at a time, beating in between each addition until fully blended before pouring in the vanilla extract. This ensures your dough stays smooth and emulsified, without any streaks or curdling.

Step 4: Combine Wet and Dry (and Swirl the Marshmallow!)

With your mixer on low, gradually work the dry ingredients into the wet until a soft, chocolaty dough forms—don’t overmix. Either lightly swirl the marshmallow fluff into the dough now for subtle ribbons, or wait until after chilling for a more dramatic swirl in each cookie.

Step 5: Chill the Dough

Cover and refrigerate the dough for at least 1 hour. This chills the butter (critical for thick cookies), makes the dough easier to handle, and helps those lovely marshmallow swirls stay distinct during baking.

Step 6: Preheat and Prep

Set your oven to 350°F (175°C) about 20 minutes before baking. Line two baking sheets with parchment paper or silicone baking mats for easy release and cleanup.

Step 7: Shape, Swirl, and Fill

Use a cookie scoop or tablespoon to portion out the dough, rolling into balls. Place 2 inches apart on the sheets, make a little indent in each, spoon in a teaspoon of marshmallow fluff, then use a toothpick to gently swirl the marshmallow—this is where the “swirl” magic happens!

Step 8: Bake to Perfection

Bake for 10-12 minutes until the edges are set but centers still look a touch soft. Optionally, dollop a bit more marshmallow on each halfway through for super-gooey, photo-worthy cookies.

Step 9: Cool and Enjoy

Allow to cool on the pan for 5 minutes to let that marshmallow settle, then transfer to a rack to finish cooling. This part is tough—your kitchen will smell divine—but it’s worth the wait!

How to Serve Chocolate Marshmallow Swirl Cookies

Garnishes

Give your Chocolate Marshmallow Swirl Cookies a little something extra with a drizzle of melted dark chocolate or a light dusting of powdered sugar—these not only look stunning, but add just the right finishing touch and a pop of flavor.

Side Dishes

Serve alongside a mug of hot cocoa, a tall glass of cold milk, or an ice-cold cold brew. For a rich dessert platter, pair with fresh berries or a scoop of vanilla bean ice cream.

Creative Ways to Present

Stack these cookies high on a cake stand for bake sales, arrange in gift boxes lined with parchment for the holidays, or slip them into cellophane bags tied with ribbon as unforgettable party favors. They’re guaranteed show-stoppers wherever they land!

Make Ahead and Storage

Storing Leftovers

Leftover Chocolate Marshmallow Swirl Cookies (if you’re lucky enough to have any!) keep beautifully in an airtight container at room temperature for up to four days. The marshmallow stays soft, and the cookies stay as tempting on day four as on day one.

Freezing

You can freeze both the dough and the baked cookies! For dough, shape and freeze cookie balls on a tray, then store in a zip-top bag and bake straight from frozen—just add a minute or two extra to the bake time. Baked cookies freeze well for up to three months; thaw at room temperature.

Reheating

To recapture fresh-baked gooeyness, pop a cookie in the microwave for 10–15 seconds. The marshmallow will melt into irresistible puddles, and the chocolate aroma will fill your kitchen all over again!
