Ingredients You’ll Need
Nothing complicated here, just simple, classic ingredients that come together to create something truly extraordinary. Each component plays a starring role: the butter delivers tender richness, sugars add sweetness and help with that perfect crisp edge, and cocoa powder gives the dough its deep chocolate allure.
- Unsalted butter (1 cup, softened): The base of moisture and flavor, softened for easy creaming.
- Granulated sugar (1 cup): Adds sweetness and helps cookies crisp up beautifully around the edges.
- Brown sugar (1 cup, packed): Injects moisture and a slight caramel note for chewiness.
- Large eggs (2): Bind everything together while keeping the cookies tender.
- Vanilla extract (2 teaspoons): Enhances the chocolate flavor with warm aromatic undertones.
- All-purpose flour (2 ½ cups): The structure-giver, providing the cookie’s soft yet sturdy texture.
- Unsweetened cocoa powder (¾ cup): For that unmistakable deep chocolate color and flavor.
- Baking soda (1 teaspoon): Helps the cookies rise just enough for a light texture.
- Salt (½ teaspoon): Balances sweetness and enhances the chocolate’s richness.
- Semi-sweet chocolate chips (1 cup): Little bursts of melty chocolate heaven throughout the cookie.
- Mini marshmallows (1 ½ cups) or marshmallow fluff (½ cup): For that signature sweet, gooey swirl that makes these cookies unforgettable.
How to Make Chocolate Marshmallow Swirl Cookies Recipe
Step 1: Get Your Oven Ready and Baking Sheets Lined
Preheat your oven to 350°F (175°C) and line your baking sheets with parchment paper. This step might feel basic, but it ensures your cookies bake evenly and don’t stick, which means easier cleanup and flawless results.
Step 2: Cream Butter and Sugars
Using softened butter, cream it together with both granulated and brown sugars until the mixture looks light and fluffy. This aeration is key for cookies that have a lovely texture with a slight crunch around the edges and softness inside.
Step 3: Incorporate Eggs and Vanilla
Add the eggs one at a time, giving the batter a good mix after each addition. Then stir in the vanilla extract for that extra boost of warm fragrant flavor that complements the chocolate perfectly.
Step 4: Mix Dry Ingredients Separately
In a different bowl, whisk together all-purpose flour, unsweetened cocoa powder, baking soda, and salt. This ensures that everything is evenly combined before joining with the wet ingredients, preventing clumps and uneven spreads.
Step 5: Combine Dry and Wet Ingredients
Gradually incorporate the dry mixture into your wet batter until just combined. Be gentle here—overmixing can make cookies tough, but a well-mixed dough will give you that soft, chewable texture we love.
Step 6: Fold in Chocolate Chips and Marshmallows
Fold in the semi-sweet chocolate chips, then gently swirl in marshmallow fluff or stir in mini marshmallows. This is where your cookies start transforming into the star of the show, with gooey pockets and melting chocolate spots throughout.
Step 7: Scoop the Dough
Drop rounded scoops of dough onto your parchment-lined sheets, spacing each cookie about 2 inches apart. This spacing gives the cookies room to spread out and develop that irresistible cookie shape.
Step 8: Bake Until Perfect
Bake for 9 to 11 minutes until the edges have set and the centers still look just a little soft. This is the perfect time frame to get a cookie that’s crisp around the edges and delightfully chewy in the middle.
Step 9: Cool and Transfer
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack. This cooling time helps the cookies set properly, preventing any crumbly mishaps when you move them.
How to Serve Chocolate Marshmallow Swirl Cookies Recipe

Garnishes
To amp up the presentation, consider sprinkling a few extra mini marshmallows or chocolate chips on top of each cookie right after baking. A light dusting of powdered sugar can also give them a festive, snow-kissed look that’s truly inviting.
Side Dishes
The richness of these cookies pairs wonderfully with a cold glass of milk or a cozy mug of hot cocoa, creating a comforting duo that’s perfect for after-school snacks or a sweet ending to dinner. Fresh berries or vanilla ice cream on the side add a fresh and creamy contrast that’s wonderfully indulgent.
Creative Ways to Present
Why not turn these cookies into a dessert centerpiece? Use them to decorate a cake platter, stack them with layers of whipped cream and chocolate sauce for a decadent icebox cake, or package them in a beautiful box as a heartfelt homemade gift that delights family and friends.
Make Ahead and Storage
Storing Leftovers
Keep your leftover Chocolate Marshmallow Swirl Cookies Recipe fresh by storing them in an airtight container at room temperature. They’ll stay soft and chewy for about 3 to 4 days—perfect for satisfying those late-night cravings without needing to bake fresh.
Freezing
If you want to enjoy these cookies later, you can freeze the baked cookies in a single layer on a baking sheet first, then transfer them to a freezer-safe bag or container. They’ll hold on to their texture and flavor for up to 3 months.
Reheating
To bring back that just-baked softness, pop frozen or refrigerated cookies in a 300°F oven for 5 to 7 minutes or microwave them for about 10 seconds. This quick reheating helps the marshmallow swirl become delightfully gooey again.
FAQs
Can I use regular marshmallows instead of mini marshmallows or marshmallow fluff?
Absolutely! Just chop the regular marshmallows into smaller pieces so they incorporate better into the dough without weighing down the cookies too much.
What if I want a less sweet version of the cookies?
Try reducing the brown sugar slightly or using dark chocolate chips instead of semi-sweet. You can also omit the marshmallow swirl, but honestly, that is what makes these cookies so magical!
Can I make this dough ahead of time?
Yes, you can prepare the dough and refrigerate it for up to 24 hours before baking. This resting time even improves the flavor and texture as the ingredients meld together.
Is it possible to make these cookies gluten-free?
Definitely. Substitute the all-purpose flour with a gluten-free baking blend designed for cookies. Just be aware that texture may vary slightly, but the taste will still be amazing!
How do I prevent marshmallows from burning during baking?
Using marshmallow fluff instead of mini marshmallows helps avoid burning since it melts smoothly into the dough. Also, baking at the recommended temperature and time ensures even cooking without over-toasting the marshmallows.
Final Thoughts
There is something so comforting and joyful about making and sharing the Chocolate Marshmallow Swirl Cookies Recipe. Whether you’re baking for a crowd or indulging in a quiet moment with a cup of coffee, these cookies bring a perfect balance of chocolatey richness and gooey marshmallow fun.
