Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This step is crucial to ensure your Chocolate Marshmallow Swirl Cookies bake evenly and achieve that delightful soft texture. While the oven heats, gather your baking sheets and line them with parchment paper, readying your space for the cookie dough.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together 2 cups of all-purpose flour, ¾ cup of unsweetened cocoa powder, 1 teaspoon of baking soda, and ½ teaspoon of salt. Ensure there are no lumps in the dry mixture, as this will enhance the overall texture of your cookies. Once well combined, set this bowl aside and prepare to move on to the next step.
Step 3: Cream Butter and Sugars
In a large mixing bowl, cream together ½ cup of unsalted butter with ½ cup of granulated sugar and ¾ cup of brown sugar until the mixture is light and fluffy, about 3-4 minutes using a hand mixer. This process incorporates air into the batter, which is essential for a chewy, tender cookie.
Step 4: Incorporate Eggs and Vanilla
Add 2 large eggs, one at a time, to the butter-sugar mixture, mixing well after each addition. Then, pour in 1 teaspoon of vanilla extract. Continue to mix until fully combined, and the batter is smooth. The richness from the eggs will enhance the cookie’s texture and flavor for your Chocolate Marshmallow Swirl Cookies.
Step 5: Combine Dry and Wet Mixtures
Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Be careful not to overmix, as this can lead to tough cookies. You want a soft dough that remains slightly sticky and rich in chocolate flavor.
Step 6: Fold in Marshmallows
Now it’s time for the fun part! Gently fold in 1 cup of mini marshmallows using a spatula. This will create beautiful swirls throughout the dough while ensuring the marshmallows are evenly distributed, giving your cookies that signature gooey texture.
Step 7: Scoop and Prepare for Baking
Using a tablespoon or cookie scoop, drop rounded tablespoons of dough onto your prepared baking sheets, spacing them about 2 inches apart to allow for spreading. The cookies will expand during baking, so give them room to breathe for optimal results.
Step 8: Bake to Perfection
Place the baking sheets in the preheated oven and bake for 10-12 minutes. Keep an eye on them; the edges should look set while the centers remain slightly soft. This combination will ensure a chewy consistency in your Chocolate Marshmallow Swirl Cookies.
Step 9: Cool Before Serving
Once baked, remove the sheets from the oven and let the cookies sit on the baking sheet for 5 minutes. They’ll firm up a bit as they cool. Afterward, transfer the cookies to a wire rack to cool completely. This final step is important for achieving that perfect texture and flavor.

How to Store and Freeze Chocolate Marshmallow Swirl Cookies
Room Temperature: Store baked cookies in an airtight container at room temperature for up to 1 week to maintain their soft, chewy texture.
Fridge: If you’d like to extend freshness, you can refrigerate the cookies in an airtight container for up to 2 weeks. Just let them come to room temperature before serving.
Freezer: Freeze cookies in a single layer on a baking sheet until solid, then transfer them to a freezer bag. They’ll keep for up to 3 months.
Reheating: To revive the softness, microwave a frozen cookie for 10-15 seconds or let them thaw at room temperature for a few minutes before enjoying your delicious Chocolate Marshmallow Swirl Cookies!

Make Ahead Options
These Chocolate Marshmallow Swirl Cookies are perfect for meal prep enthusiasts! You can prepare the cookie dough up to 24 hours in advance, which saves you precious time on busy days. Simply make the dough, scoop it onto a baking sheet lined with parchment paper, and cover it tightly with plastic wrap before refrigerating. This keeps the dough fresh and prevents the marshmallows from settling. When you’re ready to bake, just pop the dough straight from the fridge into the oven—no need to thaw! For longer storage, you can freeze the dough for up to 3 months. Just remember to increase baking time slightly if baking from frozen, ensuring you still enjoy those delicious, gooey swirls when they’re served!
