Equipment

  • 1 9x13 inch metal baking pan (Line with parchment for easy removal)
  • 1 Parchment paper (Prevents sticking and aids in lifting)
  • 1 Electric mixer (For beating frosting until fluffy)
  • 1 Mixing bowls (For beating frosting until fluffy)
  • 1 Offset spatula (For smooth, even frosting)
  • 1 Sharp knife (For clean brownie squares)

Ingredients

For the Brownie Base

  • 1 cup Unsalted butter - Melted
  • 1 cup Semi-sweet chocolate chips - Or chopped chocolate
  • ¾ cup Granulated sugar
  • ¾ cup Brown sugar - Light or dark
  • 3 large Eggs - Room temperature
  • 1 teaspoon Vanilla extract
  • 1 tablespoon Instant espresso powder - Dissolved in coffee
  • ¼ cup Brewed coffee - Cooled
  • 1 cup All-purpose flour
  • ½ cup Dutch-process cocoa powder - For rich flavor
  • ½ teaspoon Salt
  • ½ teaspoon Baking powder - Optional for slight lift

For the Coffee Frosting

  • 1 cup Unsalted butter - Room temperature
  • 2½ cups Powdered sugar - Sifted
  • 2 tablespoon Heavy cream - Adjust for consistency
  • 1 teaspoon Instant espresso powder - Dissolved in 1 tablespoon hot water
  • 1 teaspoon Vanilla extract
  • 1 pinch Salt - Balances sweetness

Instructions

  • Melt butter and chocolate until smooth, stir in sugars, then whisk in eggs, espresso, coffee, and vanilla. Fold in dry ingredients just until combined for a glossy, fudgy batter.
  • Spread batter into a prepared 9x13-inch pan and bake at 350°F (175°C) for 25–30 minutes, until the center jiggles slightly and a toothpick shows moist crumbs.
  • Let brownies cool fully in the pan before frosting to ensure clean layers and prevent melting.
  • Beat butter until fluffy, then gradually add powdered sugar, cream, and espresso until frosting is light and spreadable.
  • Spread frosting evenly over cooled brownies, chill to set, cut into squares, and serve at room temperature with optional garnish.
