Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies
Step 1: Prep Dough
Begin by preheating your oven to 350°F (175°C) and lining two baking sheets with parchment paper. In a medium bowl, whisk together 1 ¾ cups of all-purpose flour, ¾ cup of unsweetened cocoa powder, ½ teaspoon of baking soda, and ¼ teaspoon of salt. In a separate large bowl, cream together ½ cup of softened unsalted butter, ½ cup of granulated sugar, and ½ cup of brown sugar until light and fluffy, about 3 minutes.
Step 2: Combine Ingredients
With your butter and sugar mixture ready, add in 1 large egg and 1 teaspoon of vanilla extract, mixing until well combined. Gradually incorporate the dry ingredients into the wet mixture, stirring until just combined to avoid over-mixing. Gently fold in 1 cup of mini marshmallows until evenly distributed throughout the chocolate dough.
Step 3: Chill Dough (if necessary)
If the dough feels too sticky to handle, cover the bowl with plastic wrap and chill in the refrigerator for about 30 minutes. This step helps to firm up the dough, making it easier to scoop and shape into cookies. While the dough chills, you can enjoy a moment of calm or prepare your baking sheets for the next steps.
Step 4: Shape Cookies
After chilling, use a tablespoon or cookie scoop to portion out the dough and place rounded balls onto the prepared baking sheets, ensuring they are spaced about 2 inches apart. You should aim to place approximately 10-12 cookie dough balls per baking sheet, allowing room for them to spread while baking.
Step 5: Bake
Place the baking sheets in the preheated oven, baking the cookies for 10 to 12 minutes. Halfway through the baking time, rotate the sheets to ensure even cooking. The cookies should look slightly soft in the center when done; they’ll continue to set as they cool.
Step 6: Cool
Once baked, remove the cookies from the oven and let them cool on the baking sheets for about 5 minutes. Afterward, carefully transfer the cookies to a wire rack to cool completely, allowing the marshmallows to settle and maintain their gooeyness while the cookies firm up slightly.

Helpful Tricks for Chocolate Marshmallow Swirl Cookies
- Room Temperature Butter: Always start with butter that is softened to room temperature; this helps to create a light and fluffy cookie without overmixing.
- Don’t Overbake: Keep an eye on your cookies; they should be slightly soft in the center when done. Overbaking can lead to dryness.

- Real Marshmallows: Opt for mini marshmallows instead of marshmallow fluff for a better swirl and texture in your Chocolate Marshmallow Swirl Cookies.
- Even Spacing: Make sure to leave enough space (about 2 inches) between cookie dough balls on the baking sheet so they have room to spread while baking.

Chocolate Marshmallow Swirl Cookies Recipe FAQs
How do I choose the right mini marshmallows for this recipe?
Absolutely! I recommend using fresh mini marshmallows without any dark spots or a hard texture. Look for brightly colored puffs, which indicate freshness and will melt beautifully to create those gooey swirls. If you prefer a fluffier swirl, you can opt for melted marshmallows instead.
What is the best way to store leftover cookies?
To maintain the delightful texture of your Chocolate Marshmallow Swirl Cookies, store them in an airtight container at room temperature for up to 1 week. If you want them to last longer, they can be refrigerated for up to 3 days. Just make sure they’re well-sealed to prevent them from drying out.
Can I freeze the cookie dough?
Absolutely! You can freeze formed dough balls by placing them on a baking sheet lined with parchment paper until solid, then transferring them to an airtight container or a zip-top bag. They’ll stay fresh for up to 3 months. When you’re ready to bake, simply add a couple of additional minutes to the baking time.
What should I do if my cookies spread too much while baking?
If your Chocolate Marshmallow Swirl Cookies spread excessively, it might be due to the dough being too warm. Be sure to chill the dough for 30 minutes if it’s sticky before scooping it onto the baking sheet. Also, check that your baking soda is fresh, as old leavening agents can affect how well your cookies hold their shape.
Is there a way to adapt this recipe for allergies?
Very! For a nut allergy, avoid adding any nuts or nut butters. If you’re substituting for dairy, use a vegan butter alternative and make sure your marshmallows are labeled as vegan. For egg allergies, you can use a flaxseed or chia seed egg as a binder—mix 1 tablespoon of ground flaxseed or chia seeds with 2.5 tablespoons of water and let it sit until it thickens.
How long do the cookies last in the freezer?
These tasty Chocolate Marshmallow Swirl Cookies can remain in the freezer for up to 3 months. To enjoy them, simply let them thaw overnight in the fridge and then warm them up in the microwave or oven for a delightful treat once again!
