Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies
Step 1: Mix Dry Ingredients
In a large mixing bowl, whisk together 1 cup of all-purpose flour, 1/3 cup of unsweetened cocoa powder, 1/2 teaspoon of baking soda, and a pinch of salt. This combination will provide the foundation for your Chocolate Marshmallow Swirl Cookies. Set this dry mixture aside while you prepare the wet ingredients, creating a lovely cocoa aroma in your kitchen.
Step 2: Cream Butter and Sugar
In another bowl, beat together 1/2 cup of unsalted butter and 1 cup of granulated sugar, using an electric mixer on medium speed for about 3–4 minutes. You’ll want the mixture to turn light and fluffy, indicating that it’s well-aerated. This step is crucial for achieving the perfect texture in your cookies, so be patient and enjoy the transformation of your ingredients.
Step 3: Add Eggs and Vanilla
Incorporate 2 large eggs, one at a time, mixing well after each addition. Follow this with 1 teaspoon of pure vanilla extract, blending until the mixture appears smooth and shiny. The eggs provide moisture and binding to your Chocolate Marshmallow Swirl Cookies, while the vanilla adds a delightful fragrance. Ensure everything is fully combined for the best flavor.
Step 4: Combine Mixtures
Gradually add the prepared dry mixture to the wet ingredients, mixing on low speed just until the flour disappears. Avoid overmixing to keep the dough tender. You’ll notice a rich chocolate consistency forming—this is what makes your Chocolate Marshmallow Swirl Cookies so decadent.
Step 5: Swirl in Marshmallow
Gently fold in 1 cup of marshmallow fluff using a spatula, ensuring some fluff remains visible for that gorgeous swirl effect. This step will add delightful gooiness to your cookies, creating the inviting marshmallow swirls your guests will love. Handle the dough carefully to maintain the lightness of the batter.
Step 6: Chill Dough
Cover the dough with plastic wrap and refrigerate it for at least 1 hour. Chilling the dough is essential to help it firm up, reducing spreading while baking. As the dough cools, you can clean up your workspace, making the next steps even smoother.
Step 7: Preheat Oven
While the dough chills, preheat your oven to 350°F (175°C). Line your baking sheets with parchment paper to prevent sticking and ensure your cookies bake evenly. The anticipation will build as the aroma of melted chocolate fills your kitchen once the baking begins.
Step 8: Shape Cookies
Once chilled, scoop out portions of dough, around 1½ inches in diameter, placing them 2 inches apart on the prepared baking sheets. Gently indent the centers and spoon in a little extra marshmallow fluff, swirling it slightly for that signature look. This step ensures that your Chocolate Marshmallow Swirl Cookies have gooey centers with delightful marshmallow swirls.
Step 9: Bake
Bake the cookies for 10–12 minutes, until the edges are set but the centers still look soft. This contrast is vital for achieving that perfect chewy texture in your Chocolate Marshmallow Swirl Cookies. For even bolder swirls, add a few extra marshmallows halfway through baking.
Step 10: Cool and Serve
Take the cookies out of the oven and let them cool on the baking sheet for 5 minutes. Once set, transfer them to a wire rack to cool completely. The finished cookies will have crispy edges and soft, gooey centers—perfect for serving to friends and family who will surely be delighted by the rich flavors of your Chocolate Marshmallow Swirl Cookies.

Chocolate Marshmallow Swirl Cookies Recipe FAQs
How do I choose the right ripeness of marshmallows for the swirls?
Absolutely! Opt for fresh marshmallow fluff or mini marshmallows without any dark spots or hard consistency. This ensures they will melt perfectly and create those gooey swirls that we all adore in the Chocolate Marshmallow Swirl Cookies.
What’s the best way to store leftover cookies?
To keep your cookies soft and fresh, store them in an airtight container at room temperature for up to 5 days. You can also refrigerate them for about a week, but they’re best enjoyed at room temperature for that lovely, chewy texture.
Can I freeze the dough for later use?
Very! Freezing the dough is a great idea. Scoop the dough into balls, place them on a baking sheet, and freeze for about 1-2 hours until solid. Then, transfer the balls to an airtight container or freezer bag, where they can be stored for up to 3 months. When you’re ready to bake, you can simply bake them straight from the freezer, adding a couple of extra minutes to the baking time.
What if my cookies spread too much while baking?
If you find your cookies spreading excessively, it’s likely due to either warm butter or not chilling the dough long enough. Next time, ensure the butter is at room temperature and chill the dough for at least an hour before baking. This gives your Chocolate Marshmallow Swirl Cookies the better shape and texture you’re striving for!
Are these cookies safe for pets, like dogs?
