Ingredients

For the Brownies:

  • ½ cup unsalted butter
  • 4 ounces semisweet chocolate, chopped
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • ¼ cup cocoa powder
  • 1 teaspoon instant coffee granules
  • ½ cup all-purpose flour
  • ¼ teaspoon salt
  • Cocoa powder (for dusting)

For the Marshmallow Frosting:

  • 1 cup marshmallow fluff
  • ½ cup unsalted butter, softened
  • 1 teaspoon vanilla extract
  • Pinch of salt
  • 1 cup powdered sugar

Instructions

Make the Brownies:

  1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease an 8-inch square baking pan and line it with parchment paper, allowing the edges to overhang for easy removal.
  2. Melt Butter and Chocolate: In a microwave-safe bowl, melt the butter and chopped semisweet chocolate in 20-second intervals, stirring between each, until smooth. Allow it to cool slightly.
  3. Mix Wet Ingredients: In a large bowl, whisk together the granulated sugar and eggs until pale and frothy, about 2 minutes. Stir in the vanilla extract and the melted chocolate mixture.
  4. Add Dry Ingredients: Sift the cocoa powder, instant coffee granules, flour, and salt into the wet mixture. Gently fold until just combined, avoiding overmixing.
  5. Bake the Brownies: Pour the batter into the prepared pan, spreading it evenly with a spatula. Bake for 20–25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Let the brownies cool fully in the pan before slicing.

Prepare the Marshmallow Frosting:

  1. Whip Butter: In a mixing bowl, beat the softened butter with an electric mixer on medium speed until light and fluffy, about 2 minutes.
  2. Add Marshmallow Fluff: Add the marshmallow fluff, vanilla extract, and a pinch of salt, and beat until fully incorporated.
  3. Mix in Powdered Sugar: Gradually add the powdered sugar, beating on low speed until smooth. Increase the speed to medium-high and whip until light and fluffy, about 2 minutes.

Assemble the Brownies:

  1. Frost the Brownies: Once the brownies have cooled completely, spread the marshmallow frosting evenly over the top. Use an offset spatula to create swirls for a decorative touch.
  2. Dust with Cocoa Powder: Lightly dust the frosting with cocoa powder for a hot chocolate-inspired finish.
  3. Slice and Serve: Lift the brownies out of the pan using the parchment paper overhang. Slice into squares and serve. Store leftovers in an airtight container at room temperature for up to 3 days.
