Ingredients

Scale

Brownies

  • 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 your 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 later.
  2. Melt Chocolate and Butter: Using a microwave-safe bowl or a double boiler, gently melt the unsalted butter and chopped semisweet chocolate together until smooth. Allow the melted mixture to 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 everything is well combined and glossy.
  4. Add Dry Ingredients: In a separate bowl, whisk together the cocoa powder, instant coffee granules, all-purpose flour, and salt. Gradually fold these dry ingredients into the wet mixture, mixing gently until just combined to avoid overmixing.
  5. Bake Brownies: Pour the batter evenly into the prepared baking pan and smooth the top with a spatula. Bake in the preheated oven for 20-25 minutes. Check doneness by inserting a toothpick into the center—it should come out with a few moist crumbs. Let the brownies cool completely in the pan to set.
  6. Prepare Marshmallow Frosting: In a clean mixing bowl, beat together the marshmallow fluff, softened butter, vanilla extract, and a pinch of salt until the mixture is smooth and creamy. Gradually add powdered sugar while continuing to beat until the frosting becomes light, fluffy, and spreadable.
  7. Frost Brownies: Once the brownies have cooled completely, evenly spread the marshmallow frosting over the top. Use a spatula to create decorative peaks and swirls for an inviting look.
  8. Garnish and Serve: Dust the frosted brownies lightly with cocoa powder for a finishing touch. Slice into squares and serve to enjoy a decadent chocolate experience.

Notes

  • Ensure brownies are completely cool before frosting to prevent melting.
  • The instant coffee granules enhance the chocolate’s depth but will not taste like coffee.
  • You can substitute semisweet chocolate with dark chocolate for a richer flavor.
  • Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate.
  • For easier slicing, refrigerate the brownies for 30 minutes after frosting.
