Ingredients You’ll Need
Gathering a handful of simple yet essential ingredients sets the stage for these indulgent cookies.

- Unsalted butter: Provides richness and ensures your cookies stay tender and soft.
- Dark chocolate chips: Adds intense chocolate flavor with delightful melt-in-your-mouth bits.
- Granulated sugar: Sweetens and helps achieve that perfect cookie crisp along the edges.
- Light brown sugar: Introduces a subtle molasses note, enhancing the cookie’s chewiness.
- Large eggs: Bind the ingredients together and contribute to the cookie’s structure.
- Vanilla extract: Elevates flavor with warm, aromatic undertones.
- All-purpose flour: Forms the base of the dough for a sturdy yet tender bite.
- Cocoa powder: Boosts the chocolate intensity and deep, dark color.
- Baking soda: Ensures the cookies rise just right without becoming cakey.
- Salt: Balances sweetness and enhances all the chocolatey notes.
- Marshmallow fluff: The star ingredient that creates irresistible swirls and melty pockets in each cookie.
How to Make Chocolate Marshmallow Swirl Cookies Recipe
Step 1: Prep the Oven and Baking Sheets
Start by preheating your oven to 350°F (175°C). This ensures that when you’re ready to bake, your cookies will cook evenly and develop those perfect edges. Line your baking sheets with parchment paper to keep the cookies from sticking and make cleanup a breeze — a small step that makes a big difference.
Step 2: Melt Butter and Chocolate, Then Mix Sugars
Gently melt the unsalted butter with the dark chocolate chips until smooth and glossy. This warm, rich base is what makes these cookies so decadently chocolaty. Once melted, mix in both granulated and light brown sugars to add sweetness and chewiness. Stir well to combine into a luscious chocolatey batter.
Step 3: Combine Eggs and Vanilla
Next, add the large eggs and vanilla extract to the chocolate-sugar mixture. These ingredients bring moisture and structure, binding everything together while adding depth of flavor and richness that will shine in every bite.
Step 4: Mix Dry Ingredients Separately and Add
In a separate bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt. This ensures the cocoa and leavening agents are evenly distributed. Gently fold this dry mixture into the wet chocolate mixture, being careful not to overmix — you want tender cookies with just the right density.
Step 5: Fold in Marshmallow Fluff to Create Swirls
This step is the fun part. Fold in the marshmallow fluff gently so it creates beautiful swirls throughout the dough instead of fully blending in. These swirls will melt during baking, offering those signature pockets of gooey sweetness that make this Chocolate Marshmallow Swirl Cookies Recipe truly one of a kind.
Step 6: Scoop and Bake
Scoop generous spoonfuls of dough onto your parchment-lined baking sheets, leaving space between each cookie for spreading. Bake at 350°F for 10 to 12 minutes until the edges are set but the centers remain soft. Once out of the oven, allow the cookies to cool slightly—they will firm up but remain delectably chewy with marshmallow marvels inside.
How to Serve Chocolate Marshmallow Swirl Cookies Recipe

Garnishes
To add a little extra wow factor, sprinkle a few chocolate shavings or mini marshmallows on top of the cookies right after baking. A light dusting of powdered sugar can add a touch of elegance, making these treats look as irresistible as they taste.
Side Dishes
Pair these cookies with a cold glass of milk or a warm cup of coffee for the ultimate indulgence. For a festive touch, serving alongside a scoop of vanilla ice cream or a warm mug of hot cocoa can elevate the experience into a cozy dessert celebration.
Creative Ways to Present
If you want to impress guests, try stacking the cookies with layers of marshmallow fluff or even sandwiching them with chocolate ganache. Wrapped in decorative tins or tied with a ribbon, these cookies make wonderful homemade gifts that everyone will rave about.
Make Ahead and Storage
Storing Leftovers
Keep your leftover cookies fresh by storing them in an airtight container at room temperature. They will stay soft and chewy for up to 4 days, making them perfect to enjoy throughout the week or for sharing with friends.
Freezing
You can freeze the cookie dough before baking by scooping portions onto a tray, freezing until solid, then transferring to a freezer-safe bag. Bake straight from frozen, adding a couple of extra minutes to the baking time. Baked cookies also freeze well—simply thaw at room temperature before enjoying.
Reheating
For that freshly baked feeling, warm individual cookies in the microwave for 10 to 15 seconds or in a low-heat oven for 5 minutes. This will revive the gooey marshmallow swirls and melt the chocolate just right, so every bite tastes like it just came out of the oven.
FAQs
Can I use regular marshmallows instead of marshmallow fluff?
While marshmallow fluff blends more smoothly to create swirls, chopped regular marshmallows can be used in a pinch. Just fold them in carefully so they don’t fully melt away during baking, preserving some of that delightful gooey texture.
What type of chocolate works best in this recipe?
Dark chocolate chips provide a rich, intense flavor that balances the sweetness of the marshmallows beautifully. However, you can experiment with semi-sweet or milk chocolate based on your preference for a slightly sweeter or creamier cookie.
Are these cookies crunchy or soft?
This Chocolate Marshmallow Swirl Cookies Recipe creates cookies that are soft and chewy with crisp edges. The swirls of marshmallow keep the centers moist and gooey, ensuring every bite is delightfully tender.
Can I make these cookies gluten-free?
To make this recipe gluten-free, substitute the all-purpose flour with a gluten-free baking flour blend. Be sure it includes xanthan gum for structure, and check that your other ingredients don’t contain gluten.
How long will these cookies keep fresh?
Stored properly in an airtight container, these cookies will remain fresh for about 4 days at room temperature. Beyond that, freezing is your best bet to keep the marshmallow goodness intact.
