Ingredients

Scale

Brownie Ingredients

  • 1 stick unsalted butter
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 teaspoons coffee extract (or 1 tablespoon instant coffee)
  • 1/3 cup unsweetened cocoa powder
  • 1/2 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1/4 teaspoon baking powder

Coffee Frosting Ingredients

  • 1 1/2 teaspoons instant coffee granules
  • 24 tablespoons heavy whipping cream
  • 1/3 cup unsalted butter
  • 2 cups powdered sugar

Instructions

  1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease or line an 8-inch baking dish with non-stick spray or parchment paper to prevent sticking.
  2. Melt Butter: Melt 1 stick of unsalted butter in a microwave-safe bowl until fully liquid.
  3. Mix Wet Ingredients: In a large bowl, whisk together the melted butter, 1 cup granulated sugar, 2 eggs, and 1 teaspoon vanilla extract until the mixture is smooth and combined.
  4. Combine Dry Ingredients: In a separate bowl, whisk 1/3 cup unsweetened cocoa powder, 1/2 cup all-purpose flour, 1/4 teaspoon salt, and 1/4 teaspoon baking powder to mix well.
  5. Combine Wet and Dry: Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined and smooth without overmixing.
  6. Bake the Brownies: Pour the batter evenly into the prepared baking dish. Bake for 30-35 minutes or until a toothpick inserted in the center comes out mostly clean with a few moist crumbs.
  7. Cool Completely: Allow the brownies to cool completely in the pan on a wire rack before frosting to ensure the frosting spreads smoothly.
  8. Prepare Coffee Mixture: In a small bowl, dissolve 1 1/2 teaspoons instant coffee granules in 2 to 4 tablespoons of heavy whipping cream. Set aside.
  9. Make Frosting: Beat 1/3 cup unsalted butter until fluffy using a mixer. Gradually add 2 cups powdered sugar and continue mixing until smooth and creamy.
  10. Combine Frosting and Coffee: Slowly add the coffee and cream mixture to the frosting, mixing until you reach your desired spreading consistency.
  11. Frost the Brownies: Generously spread the coffee frosting over the cooled brownies. Slice into 16 pieces and serve.

Notes

  • You can adjust the coffee extract or instant coffee amount to increase or decrease the coffee flavor according to your preference.
  • For extra texture, consider adding chopped nuts such as walnuts or pecans to the brownie batter before baking.
  • Ensure brownies are fully cooled before frosting to prevent melting the frosting.
  • Store frosted brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
  • Use parchment paper for easier removal from the pan.
