Make soft, chewy cookies that taste like your favorite warm mug of hot cocoa, complete with chocolate chips and gooey mini marshmallows.

Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, softened
  • ¾ cup granulated sugar
  • ¾ cup packed light brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 ¼ cups all-purpose flour
  • ¾ cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup semi-sweet chocolate chips
  • ½ cup mini marshmallows, plus extra for topping
  • 1 cup powdered sugar (for optional glaze)
  • 2 tablespoons milk (for optional glaze)
  • ½ teaspoon vanilla extract (for optional glaze)

Instructions

  1. Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
  2. In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. This takes about 2 minutes.
  3. Beat in the eggs one at a time, then mix in the vanilla extract.
  4. In a separate medium bowl, whisk together the flour, cocoa powder, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix.
  6. Fold in the chocolate chips and the ½ cup of mini marshmallows.
  7. Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart.
  8. Bake for 9 to 11 minutes. The edges should be set, but the centers should still look slightly soft for a chewy texture.
  9. Immediately after removing the cookies from the oven, gently press a few extra mini marshmallows onto the top of each warm cookie. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
  10. If making the glaze: Whisk together the powdered sugar, milk, and vanilla extract until smooth. Drizzle over the cooled cookies.

Notes

  • For the best hot cocoa flavor, use a high-quality unsweetened cocoa powder.
  • To get the gooey marshmallow topping effect, press the marshmallows on right after baking while the cookies are hot.
  • If you prefer a fudgier cookie, chill the dough for 30 minutes before scooping.
