Ingredients

Scale

For the Coffee Brownies

  • 1/2 cup (113g) unsalted butter, melted
  • 1 cup (200g) granulated sugar
  • 2 large eggs, at room temperature
  • 1 teaspoon vanilla extract
  • 1/3 cup (32g) unsweetened cocoa powder, sifted
  • 2 tablespoons instant espresso powder
  • 1/2 cup (60g) all-purpose flour
  • 1/4 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/2 cup (85g) semi-sweet chocolate chips

For the Mocha Frosting

  • 1/4 cup (57g) unsalted butter, softened
  • 1 1/2 cups (180g) powdered sugar, sifted
  • 3 tablespoons unsweetened cocoa powder, sifted
  • 1 tablespoon strong brewed coffee, cooled
  • 1/2 teaspoon vanilla extract
  • A pinch of salt

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides to easily lift the brownies out later. In a medium bowl, sift together the flour, cocoa powder, baking powder, and salt, then set aside.
  2. Mix Wet Ingredients: In a large bowl, whisk the melted butter and granulated sugar together until well combined. Add the eggs one at a time, whisking thoroughly after each addition until the mixture is smooth and glossy. Stir in vanilla extract and instant espresso powder until fully dissolved and fragrant.
  3. Combine and Fold: Gradually add the dry ingredient mixture to the wet ingredients. Fold gently with a spatula until no dry streaks remain—avoid overmixing to keep the brownies fudgy. Fold in the semi-sweet chocolate chips evenly. Pour the batter into the prepared pan and spread it out in an even layer.
  4. Bake and Cool: Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with moist crumbs but no wet batter. The edges should be set and the top crackly. Let the brownies cool completely in the pan on a wire rack.
  5. Prepare Mocha Frosting: While the brownies cool, beat the softened butter until creamy. Gradually add powdered sugar, cocoa powder, cooled brewed coffee, vanilla extract, and a pinch of salt. Beat until the frosting is light and fluffy.
  6. Frost and Set: Spread the mocha frosting evenly over the cooled brownies. Let the frosting set for at least 30 minutes before cutting into squares and serving.

Notes

  • For a stronger coffee flavor, bloom the cocoa powder and espresso powder by whisking them into the hot melted butter for one minute before adding sugar.
  • Allow brownies to cool completely before cutting to ensure clean cuts and maintain the fudgy texture; chilling in the fridge for 30 minutes helps.
  • These brownies are versatile – crumble over yogurt or use in trifles for an extra chocolatey coffee treat.
  • Use parchment paper with an overhang to easily lift the brownies out of the pan for neat slicing.
  • Do not overbake to avoid dry, cakey brownies; slight under-doneness in the center is ideal.
