Ingredients

  • 1 1/4 cups all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1/2 cup unsalted butter, softened
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 cup mini marshmallows or 1/2 cup marshmallow fluff
  • 1 cup semi-sweet chocolate chips

Instructions

  1. Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
  2. In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt.
  3. In a large bowl, cream butter, granulated sugar, and brown sugar until light and fluffy.
  4. Beat in eggs one at a time, then add vanilla extract.
  5. Gradually mix in dry ingredients until just combined.
  6. Fold in chocolate chips and gently swirl in marshmallows or marshmallow fluff without overmixing.
  7. Drop spoonfuls of dough onto the baking sheet, spacing about 2 inches apart.
  8. Bake for 9–11 minutes, until edges are set and centers are soft.
  9. Let cookies cool on the pan for 5 minutes before transferring to a wire rack.

Notes

  • Chilling the dough for 15–20 minutes can help control spreading.
  • Use marshmallow fluff for a smoother, more even swirl.
  • Add peppermint extract or nuts for variation.
  • Reheat cookies for 10–15 seconds in the microwave to refresh gooey texture.
  • Freeze dough balls for future baking.
