How to make Chocolate Marshmallow Cookies

A full printable version of this recipe with ingredient measurements is available at the bottom of this post.

STEP ONE: Melt the butter and 1 ⅓ cup of the semi-sweet chocolate chips in a 4-quart saucepan. Stir constantly to keep it from burning, and remove from heat as soon as everything is melted. Cool for about 5-10 minutes, or your eggs will scramble when added!

STEP TWO: Combine the flour, cocoa powder, baking soda, and salt in a medium mixing bowl, then set aside.

STEP THREE: Whisk the sugar, vanilla extract, and eggs into the cooled chocolate and butter mixture. Add the dry flour mixture to the wet mixture and stir until a dough forms. Then, gently fold in the remaining chocolate chips.

STEP FOUR: Let the dough sit for about 30 minutes. I suggest placing the dough in the refrigerator for this step, especially in warmer climates.

STEP FIVE: Preheat your oven to 350 degrees and line a large baking sheet with parchment paper.

STEP SIX: Scoop out the dough with a 2-inch cookie scoop. Roll into a ball and make an indent in the center with your thumb. Place 3 miniature marshmallows in the center, then fold the dough over to cover the marshmallows. Reform into a ball, taking care to place the marshmallow side up.

STEP SEVEN: Repeat until all of the dough has been scooped. Place dough balls, marshmallow side up, on the baking sheet, and bake for about 9-10 minutes. Cookies should appear slightly moist (not wet or gooey) and dry around the edges. 

STEP EIGHT: Allow chocolate marshmallow cookies to cool for at least 5-6 minutes on the baking sheet before transferring them to a wire rack to cool completely. Enjoy!

How Can I Make the Best Marshmallow Cookies?

A few simple, essential things to remember for your chocolate marshmallow cookies to come out perfect every single time.

  • Before proceeding, ensure the melted butter and chocolate mixture has sufficiently cooled. If the last cup of chocolate chips melts in the batter, your cookies will spread while baking.
  • If you use unsalted butter, add ¼ of a teaspoon of salt to the recipe.
  • Letting the dough cool in the fridge for 25 minutes is a great way to get a much stiffer and workable dough.

Why Are My Marshmallow Chocolate Cookies Falling Apart?

For this recipe, timing is crucial. Underbaking will result in a pretty fragile cookie and prone to falling apart. It is essential to allow your cookies to cool completely before enjoying them for the same reason.

Overbaking, on the other hand, will produce an overly crunchy cookie that might even be difficult to eat. Don’t worry if the cookies seem a bit soft out of the oven — they will continue to firm up as they cool.

How Do I Keep the Marshmallows from Melting in Marshmallow Cookies?

There are two common melting mishaps with this recipe. If overbaked, the marshmallows melt completely inside the dough and cause the cookies to become solid as a rock. Be sure to set a timer!

Secondly, be sure that the marshmallow side of your cookie dough balls is facing up in the oven. Otherwise, the marshmallow will likely melt and pool onto the baking sheet. No fun!

How Do I Store Leftover Chocolate Chip Marshmallow Cookies?

Chocolate marshmallow cookies, once baked and stored in an airtight container, can last up to 2 weeks at room temperature or 2 months in the refrigerator. They can also last for up to 8 months when stored in the freezer.
