Print Recipe

Make rich, fudgy brownies that taste like your favorite mug of hot cocoa, complete with a gooey marshmallow swirl.

Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter
  • 1 1/4 cups granulated sugar
  • 3/4 cup packed light brown sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 3/4 cup unsweetened cocoa powder
  • 1 cup all-purpose flour
  • 1/2 teaspoon salt
  • 1/2 cup semi-sweet chocolate chips
  • 1 cup mini marshmallows

Instructions

  1. Preheat your oven to 350 degrees F. Line a 9×9 inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. Melt the butter in a medium saucepan over low heat. Remove from heat.
  3. Whisk the granulated sugar and brown sugar into the melted butter until combined.
  4. Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  5. In a separate bowl, whisk together the cocoa powder and flour. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
  6. Fold in the chocolate chips.
  7. Pour half of the batter into the prepared pan and spread evenly.
  8. Sprinkle the mini marshmallows evenly over the batter layer.
  9. Top with the remaining batter, spreading gently over the marshmallows.
  10. Bake for 30 to 35 minutes, or until a toothpick inserted near the edge comes out with moist crumbs attached. The center should still look slightly soft for a fudgy texture.
  11. Let the brownies cool completely in the pan on a wire rack before lifting out and cutting into squares.

Notes

  • For a toasted marshmallow effect, place the cut brownies under the broiler for 30 to 60 seconds after they have cooled slightly, watching constantly to prevent burning.
  • Use high-quality cocoa powder for the best chocolate flavor.
  • If you prefer a slightly lighter texture, you can substitute 1/4 cup of the cocoa powder with instant espresso powder.
