Chocolate Marshmallow Cookie Ingredients

A complete list of ingredients and amounts can be found in the recipe card below.

All-purpose flour: It provides the structure for the chocolate cookies with marshmallows, giving them a soft and chewy texture.
Cornstarch: A secret ingredient that helps to create a tender crumb. It softens the flour’s gluten, creating a more delicate cookie that melts in your mouth.
Baking soda and baking powder: Check both batches are fresh for best results.
Unsweetened cocoa powder: I recommend a high-quality, unsweetened natural cocoa powder if possible for a delicious chocolate flavor.
Chocolate chips: Semi-sweet chocolate chips melt beautifully, adding a delightful gooeyness to the cookies.
Unsalted butter: Use room temperature butter for easy creaming. I recommend unsalted vs salted butter for this recipe.
Light brown sugar: Adds moisture and caramel flavor. This contributes to the chewy texture of the cookies.
Eggs: Bind the ingredients together and add richness and moisture.
Mini marshmallows: These fluffy treats provide a sweet, chewy texture and a fun surprise in every bite.

Prepare dry ingredients: Combine flour, cornstarch, baking soda, baking powder, and salt. Add the cocoa powder and chocolate chips and mix.
Mix wet ingredients: In a separate bowl, use a hand mixer to combine the butter, light brown sugar, and granulated sugar. Add the eggs one at a time. Combine the egg and vanilla extract.
Combine mixtures: Add the dry mixture slowly in two parts, mixing until all the flour is incorporated.
Chill the dough: Pop in the fridge for 30 minutes.
Shape the cookies: Portion the dough into your hand. Flatten the cookie dough balls into a disc and place 3 or 4 mini marshmallows in the center. Fold the dough around the marshmallows to form a stuffed cookie dough ball.
Chill again: Chill the dough balls in the freezer.
Bake cookies: Bake on a cookie sheet and then let the baked cookies cool completely.

Substitutions and Variations

Gluten-free option: Use your preferred glute-free flour in place of regular flour.
Butter: Swap with coconut oil or vegetable oil for a dairy-free version of these chocolate marshmallow cookie recipe.
Sugars: Switch with light brown sugar for dark brown sugar for a richer flavor.
Chocolate chips: Replace semi-sweet chocolate chips with milk chocolate, dark chocolate, or white chocolate chips. Use carob chips for a caffeine-free option. Chopped chocolate is yummy, too.
Vegan option: Substitute eggs with flaxseed meal (1 tablespoon ground flaxseed and 2½ tablespoons water, let sit to thicken). Choose a butter substitute and vegan marshmallows, not the ones with gelatin. (I love these vegan marshmallows!)
Marshmallows: Try making this recipe with marshmallow fluff instead of regular marshmallows.
Cornstarch: You can leave out cornstarch or replace it with arrowroot powder for similar results.
Nutty marshmallow cookies: Add chopped nuts like walnuts or pecans for extra crunch and flavor.
S’mores variation: Add crushed graham crackers into the dough and top with chocolate squares and marshmallows.
Mint chocolate marshmallow cookies: Add peppermint extract and use mint chocolate chips.
Fruity marshmallow cookies: Mix dried fruits like cherries or cranberries for a chewy texture and fruity flavor.

Appetizer: Start with dirty martini shrimp, ground turkey potstickers or these fun air fryer mac and cheese balls!

How to Store Chocolate Marshmallow Cookies

Store: Keep them at room temperature for 4 days in an airtight container.
Freezer: I wouldn’t recommend freezing the cookies due to the marshmallows.
