Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies
Step 1: Preheat Your Oven
Begin your delightful baking journey by preheating your oven to 350°F (175°C). While it warms up, line two baking sheets with parchment paper to ensure easy removal of your Chocolate Marshmallow Swirl Cookies later. The parchment will help create perfectly baked bottoms, so don’t skip this important step!
Step 2: Whisk Dry Ingredients
In a medium bowl, whisk together 2 cups of all-purpose flour, 1/2 cup cocoa powder, 1 teaspoon baking soda, and 1/4 teaspoon salt until well combined. This combination ensures that the dry ingredients are evenly distributed, giving your cookie dough a rich chocolate flavor and a light texture. Set this bowl aside for the next step.
Step 3: Cream the Butters and Sugars
In a large mixing bowl, cream together 1/2 cup softened unsalted butter, 1/2 cup granulated sugar, and 1/2 cup brown sugar using an electric mixer on medium speed for about 2-3 minutes. The mixture should turn light and fluffy, with a pale color. This step adds air to your dough, ensuring a deliciously tender cookie.
Step 4: Incorporate Egg and Vanilla
Next, beat in 1 large egg and 1 teaspoon of vanilla extract into the creamed mixture until everything is fully combined and smooth. This will enrich the dough as the egg binds your ingredients while the vanilla adds lovely, aromatic flavor. Make sure to scrape down the sides of the bowl for even mixing.
Step 5: Mix in Dry Ingredients
Gradually add the dry ingredient mixture from Step 2 to your wet ingredients, mixing until just combined. Be careful not to overmix the batter; stopping when no flour streaks remain will help maintain a tender texture in your Chocolate Marshmallow Swirl Cookies.
Step 6: Fold in Chocolate and Marshmallows
Gently fold in 1 cup of semi-sweet chocolate chips and 1 cup of mini marshmallows into the dough. If you’re feeling extra indulgent, add 1/2 cup of marshmallow fluff to create a gooey swirl. Use a spatula to ensure that these sweet additions are evenly distributed throughout the dough.
Step 7: Scoop the Dough
Using a cookie scoop or spoon, drop rounded tablespoons of dough onto the prepared baking sheets, leaving 2 inches of space between each scoop. This spacing will give your Chocolate Marshmallow Swirl Cookies room to spread as they bake, resulting in perfect, evenly shaped treats.
Step 8: Bake the Cookies
Place the baking sheets in the preheated oven and bake for 8-10 minutes. You’ll know they’re ready when the edges are set, but the centers still look slightly soft and puffy. The marshmallows may begin to toast slightly, adding a delightful aroma—keep an eye on them to avoid burning!
Step 9: Cool and Enjoy
Once baked, allow the cookies to cool on the baking sheets for about 5 minutes before transferring them to a wire rack. This resting time allows the cookies to firm up slightly while still maintaining a soft, gooey interior. Serve warm for a delightful treat that will surely melt hearts!

Make Ahead Options
These Chocolate Marshmallow Swirl Cookies are perfect for meal prep enthusiasts! You can prepare the dough up to 24 hours in advance; simply make it, scoop into balls, and refrigerate (this helps deepen the flavors). If you’re even busier, you can freeze the unbaked dough for up to 3 months—just place the cookie balls in a freezer-safe bag. When you’re ready to enjoy, bake directly from the freezer, adding an extra minute or two to the baking time. This way, you can savor that warm, gooey goodness with minimal effort any time! Just remember to keep them stored in an airtight container once baked to maintain their delightful texture.
How to Store and Freeze Chocolate Marshmallow Swirl Cookies
Room Temperature: Store cookies in an airtight container at room temperature for up to 5 days to maintain their soft and chewy texture.
Fridge: If you’d like to keep them fresh longer, refrigerate in an airtight container for up to 1 week. This may slightly alter the texture, making them a bit firmer.
Freezer: Freeze your Chocolate Marshmallow Swirl Cookies for up to 3 months by placing them in a freezer-safe container. Layer parchment paper between cookies to prevent sticking.
Reheating: To enjoy your cookies warm, briefly reheat in the microwave for 10-15 seconds or in a preheated oven at 350°F (175°C) for 5-7 minutes.

Chocolate Marshmallow Swirl Cookies Recipe FAQs
How do I choose the right chocolate and marshmallows?
For these cookies, I recommend using semi-sweet chocolate chips for a perfect balance of sweetness and richness. If you like a deeper chocolate flavor, you can opt for dark chocolate chips. When selecting mini marshmallows, look for fresh ones that are soft and fluffy. Avoid any that show signs of hardening or have dark spots, as they may not melt properly in your cookies.
How should I store Chocolate Marshmallow Swirl Cookies?
Store your cookies in an airtight container at room temperature for up to 5 days. This keeps them soft and chewy! If you want to extend their shelf life, you can refrigerate them; they’ll stay fresh for about a week, though the texture may become a little firmer. Just ensure they are well-sealed to prevent drying out.
Can I freeze the Chocolate Marshmallow Swirl Cookies?
Absolutely! You can freeze your cookies for up to 3 months. To do so, let them cool completely, then layer them in a freezer-safe container with parchment paper between each cookie to prevent sticking. When you’re ready for a treat, simply take out the desired amount and reheat them in the microwave for 10-15 seconds, or pop them in a preheated oven at 350°F (175°C) for 5-7 minutes.
What should I do if my cookies spread too much while baking?
If you notice your cookies spreading too much, it could be due to your butter being too warm or melted when mixed. Ensure your butter is softened but not melted. You can also chill the cookie dough for about 30 minutes before baking; this helps the cookies maintain their shape better. Additionally, make sure to measure your flour accurately, as too little can lead to spreading.
Are there any allergy considerations for these cookies?
Yes, if you are baking for someone with allergies, be mindful of common allergens in this recipe. The cookies contain gluten (from all-purpose flour), dairy (from butter), and eggs. For gluten-free cookies, substitute with a gluten-free flour blend. You could use a dairy-free margarine instead of butter and replace the egg with a flax egg (1 tbsp ground flaxseed mixed with 2.5 tbsp water). Always ensure to check labels on pre-packaged items like marshmallows and chocolate chips, as they may contain allergens.
Can these cookies be made vegan?
Definitely! You can create a vegan version of Chocolate Marshmallow Swirl Cookies. Simply substitute the unsalted butter with a dairy-free margarine and replace the egg with a flax egg (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water). Additionally, be sure to use dairy-free chocolate chips and marshmallows. Following these swaps will allow everyone to enjoy these delightful cookies.
