Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, softened to room temperature
  • 1 cup granulated sugar
  • 1 cup packed light brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 2 ½ cups all-purpose flour
  • ½ cup unsweetened cocoa powder (Dutch-processed recommended)
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup semi-sweet chocolate chips
  • ½ cup marshmallow fluff (or 12–15 mini marshmallows per cookie) for filling
  • ½ cup marshmallow fluff for drizzle
  • 1–2 teaspoons milk
  • Optional toppings: crushed candy canes, festive sprinkles, mini chocolate chips, or powdered sugar

Instructions

  1. Prep your ingredients: Take butter and eggs out of the refrigerator about 30 minutes before baking. In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt. Set aside.
  2. Cream the butter and sugars: In the bowl of a stand mixer (or large bowl with a hand mixer), beat softened butter, granulated sugar, and brown sugar on medium speed for 3-4 minutes until light, fluffy, and pale. Scrape down the sides halfway through.
  3. Add the eggs and vanilla: Add eggs one at a time, beating well after each addition. Mix in vanilla extract. The mixture may look curdled; that’s normal.
  4. Mix in the dry ingredients: With mixer on low speed, gradually add the flour mixture. Mix just until flour disappears. Fold in chocolate chips with a spatula.
  5. Chill the dough: Cover the bowl with plastic wrap and refrigerate for at least 30 minutes (up to 48 hours).
  6. Preheat and prep: Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper. Let dough sit at room temperature for 5 minutes.
  7. Assemble the cookies: Using a 2-tablespoon cookie scoop, scoop a ball of dough and flatten slightly in your palm. Place about 1 teaspoon of marshmallow fluff (or 3-4 mini marshmallows) in the center. Scoop another ball of dough, flatten, and place on top. Gently press edges together to seal marshmallow inside. Roll into a smooth ball. Repeat for 18-20 cookies.
  8. Bake: Place cookie balls 2 inches apart on prepared baking sheets. Bake for 10-12 minutes. Cookies will look slightly puffed with set edges and soft centers. Do not overbake.
  9. Cool completely: Let cookies cool on baking sheet for 5 minutes, then transfer to a cooling rack to cool completely.
  10. Make the marshmallow drizzle: In a small microwave-safe bowl, combine remaining ½ cup marshmallow fluff with 1 teaspoon milk. Microwave for 10-15 seconds, then stir. Add more milk if needed to reach a thick but pourable consistency. Transfer to a small piping bag or zip-top bag with a tiny corner snipped off.
  11. Drizzle and decorate: Once cookies are completely cool, drizzle marshmallow mixture over tops in a zigzag pattern. Immediately sprinkle with chosen toppings. Let drizzle set for 10-15 minutes before serving.

Notes

Chilling the dough is crucial to prevent spreading. Seal marshmallow completely inside dough to avoid leaks. Use a light-colored baking sheet to prevent over-browning. Rotate baking sheets halfway through baking. Let cookies rest on the pan for 5 minutes before transferring. For the drizzle, less is more. Optionally, toast the marshmallow drizzle with a kitchen torch for a smoky flavor.
