Ingredients
  

For the Brownies
  • 1 cup Unsalted butter, melted
  • 2 cups Granulated sugar
  • 4 large Eggs
  • 1 cup All-purpose flour
  • ¾ cup Unsweetened cocoa powder
  • ½ teaspoon Salt
  • ½ cup Brewed coffee, cooled - Use strong coffee for best flavor
  • 2 teaspoon Vanilla extract
  • 1 tablespoon Instant coffee or espresso powder - Enhances mocha taste
For the Coffee Buttercream Frosting
  • ½ cup Unsalted butter, softened
  • 3 cups Powdered sugar
  • 3 tablespoon Brewed coffee, cooled - Add more for thinner texture
  • 1 teaspoon Vanilla extract
  • 2 teaspoon Instant coffee or espresso powder - Intensifies coffee flavor
  • Pinch Salt - Balances sweetness
Optional Toppings
  • Chocolate shavings - For garnish
  • Chocolate-covered espresso beans - Fancy topping
  • Cocoa powder - Light dusting

Equipment

  • 1 9x13-inch baking pan (Line with parchment for easy removal)
  • 1 Large mixing bowl (For wet ingredients)
  • 1 Medium bowl (For dry ingredients)
  • 1 Whisk (To combine batter)
  • 1 Hand or Stand Mixer (For frosting)
  • 1 Offset spatula or butter knife (To spread frosting evenly)
  • 1 Wire rack (To cool brownies completely)

Method
 

  1. Preheat oven to 350°F (177°C). Line a 9x13-inch baking pan with parchment paper, leaving overhang on the sides for easy removal.
  2. Whisk melted butter and sugar until smooth. Add eggs one at a time, then stir in cooled brewed coffee, vanilla, and instant coffee powder. In a separate bowl, whisk flour, cocoa powder, and salt. Fold dry ingredients into wet mixture until just combined.
  3. Pour batter into the prepared pan and spread evenly. Bake for 28–32 minutes, until a toothpick inserted in the center comes out with moist crumbs. Do not overbake. Let cool completely in the pan on a wire rack.
  4. Beat softened butter until fluffy. Gradually add powdered sugar, then mix in brewed coffee, vanilla, instant coffee powder, and salt. Beat until light and creamy.
  5. Spread frosting evenly over cooled brownies. Add chocolate shavings or espresso beans if desired. Slice into squares and serve.
