Ingredients

(Tip: You’ll find the full list of Ingredients and measurements in the recipe card below.)

All-purpose flour
Unsweetened cocoa powder
Baking soda
Salt
Unsalted butter
Granulated sugar
Brown sugar
Eggs
Vanilla extract
Milk
Marshmallows or marshmallow fluff

Directions

I start by preheating the oven and lining a baking sheet with parchment paper.

In a bowl, I whisk together the flour, cocoa powder, baking soda, and salt. In a separate bowl, I cream the butter with the granulated sugar and brown sugar until smooth. I mix in the eggs, vanilla extract, and milk until fully combined.

I gradually add the dry ingredients to the wet ingredients, mixing just until a soft chocolate dough forms.

I scoop portions of dough onto the prepared baking sheet. I press marshmallows or spoon small amounts of marshmallow fluff onto each cookie, then gently swirl it into the dough using a toothpick or knife.

I bake the cookies until the edges are set but the centers are still soft. I let them cool on the baking sheet for a few minutes before transferring them to a rack.

Servings And Timing

I usually get about 18 to 20 cookies from this recipe.
Preparation takes around 15 minutes, and baking time is about 10 to 12 minutes, making the total time roughly 30 minutes.

Variations

I sometimes add chocolate chips to the dough for extra richness. When I want a s’mores-style twist, I sprinkle crushed graham crackers on top before baking. I also like using mini marshmallows for a more even swirl throughout the cookies.

Storage/Reheating

I store these cookies in an airtight container at room temperature for up to 3 days. When I want them warm and gooey, I heat them briefly in the oven for a few minutes. I avoid microwaving too long so the marshmallow doesn’t become too sticky. Chocolate Marshmallow Swirl Cookies

FAQs

Can I use marshmallow fluff instead of whole marshmallows?

Yes, I use marshmallow fluff often because it swirls easily into the dough.

Why did my marshmallows melt too much?

I find this happens if I use very large marshmallows or bake the cookies too long.

Can I chill the dough ahead of time?

I can chill it for about 30 minutes if the dough feels too soft to handle.

Are these cookies very sweet?

I find them balanced, with the marshmallow adding sweetness to the rich chocolate base.

Can I freeze these cookies?

I freeze the baked cookies and thaw them at room temperature before serving.

Conclusion

I enjoy making Chocolate Marshmallow Swirl Cookies because they’re fun, rich, and incredibly comforting. The combination of deep chocolate flavor and gooey marshmallow makes them irresistible, and they’re a recipe I love turning to whenever I want a cozy, crowd-pleasing treat.
