12 cupunsalted butter, softened to room temperature
2cupspowdered sugar
14 cupunsweetened cocoa powder
2tablespoonsmilk
1teaspoonvanilla extract
1teaspooninstant coffee granules dissolved in hot water
Instructions
Preheat your oven to 350°F (175°C). Prepare a 9x13-inch baking pan by greasing it with butter or lining it with parchment paper.
In a large mixing bowl, combine the melted butter and granulated sugar. Use a whisk to blend them until smooth and creamy.
Crack in the eggs one at a time, whisking thoroughly after each addition. Stir in the vanilla extract until evenly mixed.
In a separate bowl, sift together the flour, cocoa powder, baking powder, and salt. Slowly fold these dry ingredients into the wet mixture.
Dissolve the instant coffee granules in a small amount of warm water and mix into the batter. Fold in the chocolate chips.
Pour the brownie batter into the prepared baking pan and spread it out evenly. Bake for 25-30 minutes, or until a toothpick inserted comes out with a few moist crumbs.
Allow the brownies to cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely.
In a medium bowl, beat the softened butter until light and fluffy. Gradually add the powdered sugar and cocoa powder, mixing until fully incorporated. Add the milk and dissolved coffee mixture, beating until smooth.
Once the brownies are completely cooled, use a spatula to evenly coat the top with the frosting.
Cut the brownies into squares and serve them on your favorite dessert plate.
Notes
For an elegant finishing touch, dust with cocoa powder or add chocolate shavings.
