How to Make Chocolate Marshmallow Swirl Cookies

1. Prepare the Dough

Start by creaming your butter with both sugars until the texture is light and fluffy. This process traps air in the dough, helping your cookies rise and stay soft. Once that’s done, mix in the eggs and vanilla. Gradually add in the flour, cocoa powder, baking soda, and salt. Be gentle—overmixing can toughen the dough.

2. Add the Swirls

Fold in the chocolate chips until they are well dispersed. Then, gently swirl in the mini marshmallows. Avoid over-stirring at this stage to preserve the shape of the marshmallows, allowing them to melt into gooey ribbons during baking.

3. Chill the Dough

Let your dough rest in the fridge for 10–15 minutes. This chilling step is crucial. It prevents the cookies from spreading too much and helps all the flavors meld. If you skip this step, your cookies might lose their chewy structure.

4. Bake to Perfection

Preheat your oven to 350°F (175°C). Line your baking sheet with parchment paper. Scoop out dough balls and space them evenly. Bake for 9–11 minutes, or until the edges are firm and the centers still look a bit soft. Once baked, let the cookies cool on the sheet for a few minutes before transferring them to a wire rack.

Tips for Best Results

Maximize your cookie success with these tried-and-true tips:

  • Don’t skip the chill: Chilling the dough enhances flavor and shape.
  • Watch your baking time: Underbaking by a minute keeps cookies extra chewy.
  • Use parchment paper: Prevents sticking and promotes even browning.
  • Let them cool: Marshmallows are molten straight from the oven—give them a few minutes.

Variations to Try

Feel like experimenting? These twists make the recipe even more fun:

  • Peppermint Marshmallow: Add peppermint extract and sprinkle crushed candy canes on top.
  • S’mores Style: Add graham cracker bits for a campfire-inspired version.
  • Nutty Crunch: Stir in walnuts or pecans for added texture.
  • Spiced Cocoa: Add a dash of cinnamon and cayenne for a spicy twist.

How to Store and Freeze Chocolate Marshmallow Swirl Cookies

You don’t have to eat them all at once (but we won’t judge if you do):

  • Room Temperature: Keep cookies in an airtight container for up to five days.
  • Freezing Dough: Scoop into dough balls and freeze. Bake directly from frozen with a few extra minutes.
  • Freezing Baked Cookies: Layer with parchment paper in a freezer-safe container for up to 3 months.

FAQs About Chocolate Marshmallow Swirl Cookies

What makes Chocolate Marshmallow Swirl Cookies chewy?

Brown sugar and butter contribute to a moist, chewy center while still giving structure.

Can I use large marshmallows instead of mini?

Yes, but you should chop them into smaller pieces for even distribution and better swirls.

Why did my cookies spread too much?

Likely because the dough wasn’t chilled. Chill for 10 minutes to set and reduce spreading.

Can I make these cookies gluten-free?

Absolutely. Just replace the flour with a 1:1 gluten-free blend.

Chocolate Marshmallow Swirl Cookies are more than just a treat—they’re a little piece of joy in every bite. Easy to prepare, endlessly customizable, and full of that gooey, chocolatey magic you crave, these cookies deserve a spot in your permanent recipe rotation.
