Guinness Brownies with Frosting

Print Recipe

Rich, fudgy brownies with a Guinness-infused frosting, perfect for St. Patrick’s Day or dinner parties.

Ingredients

Scale
  • 1 bottle (11.2-12 ounces) Guinness Draught Stout beer, reduced
  • 3/4 cup unsalted butter, for brownie base
  • 8 ounces semi-sweet chocolate, coarsely chopped
  • 1 and 1/4 cups granulated sugar
  • 3 large eggs, at room temperature
  • 1 teaspoon pure vanilla extract
  • 1 cup all-purpose flour
  • 1/2 teaspoon salt
  • 1/2 teaspoon espresso powder (optional)
  • 1/2 cup unsalted butter, softened, for frosting
  • 2 cups confectioners’ sugar
  • 2–3 tablespoons reduced Guinness, for frosting
  • 1 teaspoon espresso powder, for frosting (optional)
  • 1/2 teaspoon pure vanilla extract, for frosting
  • 1/4 teaspoon salt, for frosting

Instructions

  1. Reduce the Guinness. Pour the bottle into a small saucepan and bring to a boil. Simmer until it reduces to 2/3 cup. Allow it to cool for about 10 minutes before using.
  2. Preheat the oven to 350°F (175°C) and grease a 9-inch square baking pan.
  3. Melt the butter and chocolate. In a microwave-safe bowl, combine butter and chopped semi-sweet chocolate. Heat in short bursts, stirring between intervals, until smooth.
  4. Mix in sugar and Guinness. Whisk granulated sugar into the melted chocolate mixture, then whisk in 1/2 cup of the reduced Guinness.
  5. Add eggs and vanilla. Incorporate the eggs and vanilla extract into the chocolate mixture until glossy.
  6. Fold in dry ingredients. Gently fold in flour, salt, and optional espresso powder until just combined.
  7. Bake the batter in the prepared pan for 32 minutes.
  8. Cool completely. Let the brownies cool in the pan before frosting.
  9. Make the frosting. Beat softened butter until smooth, then gradually add confectioners’ sugar, reduced Guinness, espresso powder, vanilla extract, and salt.
  10. Frost and serve. Spread frosting over cooled brownies, cut into squares, and serve.

Notes

For a fudgier center, check for doneness a few minutes early. Store frosted brownies in an airtight container at room temperature for up to 2 days.
