Ingredients

Scale

Brownie Batter

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

Marshmallow Frosting

  • 1 cup marshmallow fluff
  • 1/2 cup unsalted butter, softened
  • 1 teaspoon vanilla extract
  • Pinch of salt
  • 1 cup powdered sugar

Instructions

  1. Preheat Oven: Preheat the oven to 350°F (175°C). Grease and line an 8×8-inch baking pan with parchment paper to ensure easy removal of the brownies after baking.
  2. Melt Chocolate and Butter: In a microwave-safe bowl or using a double boiler, gently melt the unsalted butter and chopped semisweet chocolate together until smooth. Let the mixture cool slightly to avoid cooking the eggs in the next step.
  3. Mix Batter: Whisk the granulated sugar, eggs, and vanilla extract into the melted chocolate and butter mixture until well combined, creating a smooth and glossy batter.
  4. Add Dry Ingredients: In a separate bowl, whisk together the cocoa powder, instant coffee granules, all-purpose flour, and salt. Gradually fold this dry mixture into the wet chocolate mixture until just combined, taking care not to overmix for tender brownies.
  5. Bake Brownies: Pour the batter into the prepared baking pan and spread evenly. Bake in the preheated oven for 20 to 25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Let the brownies cool completely in the pan before frosting.
  6. Prepare Marshmallow Frosting: In a mixing bowl, beat together the marshmallow fluff, softened butter, vanilla extract, and a pinch of salt until smooth and creamy. Gradually incorporate the powdered sugar, continuing to beat until the frosting becomes light, fluffy, and spreadable.
  7. Frost Brownies: Once the brownies have fully cooled, spread the marshmallow frosting evenly over the top using a spatula, creating decorative peaks if desired.
  8. Garnish and Serve: Lightly dust the surface of the frosting with cocoa powder to add an elegant finishing touch. Slice the brownies into squares and serve immediately or store for later enjoyment.

Notes

  • Ensure brownies are completely cool before frosting to prevent the marshmallow fluff from melting.
  • If you prefer a stronger coffee flavor, you can increase the instant coffee granules to 1 1/2 teaspoons.
  • These brownies can be stored in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.
  • For a gluten-free option, substitute all-purpose flour with an equal amount of gluten-free baking flour blend.
  • Use parchment paper with an overhang on the pan for easy lifting of the entire brownie slab.
