How to Make Chocolate Marshmallow Swirl Cookies
-
Preheat Oven: Start by preheating your oven to 350°F (175°C) and line two baking sheets with parchment paper. This ensures your cookies bake evenly and don’t stick.
-
Whisk Dry Ingredients: In a medium bowl, whisk together all-purpose flour, cocoa powder, baking soda, and salt. This step allows for even distribution of the dry ingredients.
-
Cream Butter and Sugars: In a larger bowl, cream together the softened unsalted butter, granulated sugar, and brown sugar until the mixture becomes pale and fluffy, about 2-3 minutes. This creates the necessary airiness for your cookies.
-
Add Egg and Vanilla: Mix in the egg and vanilla extract until well combined. The egg acts as a binder, while the vanilla adds a delicious layer of flavor.
-
Combine Ingredients: Gradually incorporate the dry ingredients into the wet mixture in 2-3 additions, mixing on low to avoid overmixing. You want a smooth cookie dough without tough textures.
-
Fold in Chocolate and Marshmallows: Gently fold in the semi-sweet chocolate chips, mini marshmallows, and marshmallow fluff until everything is evenly distributed throughout the dough.
-
Scoop Dough: Using a cookie scoop or tablespoon, scoop the dough onto the prepared baking sheets, spacing them about 2 inches apart. This gives the cookies room to spread.
-
Bake: Place in the oven and bake for 8-10 minutes, until the edges are set but the centers are soft. Keep an eye on the marshmallows—they should be slightly caramelized.
-
Cool Cookies: Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely, allowing them to firm up slightly.
Optional: Serve warm with a scoop of vanilla ice cream for an extra indulgent treat!

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 by chilling it in the refrigerator. Just scoop the dough onto your baking sheets, cover them with plastic wrap, and refrigerate.

Additionally, if you want to make them even further in advance, you can freeze the scooped dough in an airtight container for up to 3 months—just remember to label them! When ready to enjoy, bake directly from frozen, adding a couple of extra minutes to the baking time, and savor these delicious treats without the last-minute rush!
Expert Tips for Chocolate Marshmallow Swirl Cookies

Chocolate Marshmallow Swirl Cookies Recipe FAQs
What is the best way to select marshmallows for this recipe?
Absolutely! When picking marshmallows, look for fresh mini marshmallows without any dark spots or hard edges. Fresh marshmallows will provide that soft, gooey texture that contrasts beautifully with the chocolate in your cookies.
How should I store my Chocolate Marshmallow Swirl Cookies?
You can store your cookies in an airtight container at room temperature for up to 1 week. For extra freshness and to keep them chewy, you can also refrigerate them for up to 2 weeks. Just let them sit out for a bit before enjoying.
Can I freeze Chocolate Marshmallow Swirl Cookies?
Yes, you can freeze these delightful treats! First, layer them between sheets of parchment paper in an airtight container or freezer-safe bag. They can be stored for up to 3 months. To enjoy, simply thaw at room temperature or microwave for a few seconds to restore that gooey texture.
What should I do if my cookie dough is too sticky?
If you find your dough is too sticky, don’t worry! You can either chill the dough in the fridge for about 30 minutes to firm it up or add a little extra flour, a tablespoon at a time, until it reaches the desired consistency. It’s perfectly normal for cookie dough to vary, especially based on humidity and ingredient measurements.
Can I make these cookies vegan-friendly?
Yes, you certainly can! For a vegan version, simply substitute the unsalted butter with a plant-based margarine or vegan butter, replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons of water), and ensure your chocolate chips are dairy-free. This way, you can still indulge in those warm, gooey Chocolate Marshmallow Swirl Cookies!
How can I tell when my cookies are done baking?
To ensure perfectly baked cookies, keep an eye on them during the last few minutes in the oven. You’ll want the edges to be set, while the centers remain soft and a little underbaked. The marshmallows should be lightly caramelized; this indicates that your cookies are ready to be taken out. Don’t worry, they’ll firm up as they cool!
