Print Recipe

Ingredients

Scale
  • 1 (11.2–12-ounce) bottle Guinness Draught Stout beer, reduced
  • 3/4 cup unsalted butter (for batter)
  • 2 (4-ounce) bars 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 (for frosting)
  • 2 cups confectioners’ sugar
  • 2–3 tablespoons reduced Guinness (for frosting)
  • 1 teaspoon espresso powder (for frosting)
  • 1/2 teaspoon pure vanilla extract (for frosting)
  • 1/4 teaspoon salt (for frosting)

Instructions

  1. Reduce the Guinness: Pour the bottle into a saucepan, bring to a boil, and simmer until reduced to 2/3 cup, about 12-15 minutes. Let cool completely.
  2. Prepare the pan: Preheat the oven to 350°F (175°C). Grease a 9-inch square baking pan and line with parchment.
  3. Melt the butter and chocolate: Combine 3/4 cup butter and the chopped semi-sweet chocolate in a microwave-safe bowl. Microwave in 30-second increments until smooth.
  4. Combine sugar and Guinness: Whisk the granulated sugar into the melted chocolate and butter; whisk in 1/2 cup of the reduced Guinness.
  5. Add eggs and vanilla: Whisk in the eggs one at a time, then stir in 1 teaspoon vanilla extract.
  6. Add dry ingredients: Fold in the flour, salt, and optional espresso powder until just incorporated.
  7. Bake: Pour the batter into the prepared pan and bake for 32-35 minutes, until a toothpick comes out with a few moist crumbs.
  8. Cool: Allow the brownies to cool completely in the pan before frosting.
  9. Make the frosting: Beat the softened butter until smooth, then gradually add the confectioners’ sugar, reduced Guinness, espresso powder, vanilla extract, and salt until smooth.
  10. Frost and serve: Spread frosting over cooled brownies, slice into squares, and serve.

Notes

For firmer frosting, start with 2 tablespoons of reduced Guinness and adjust to desired consistency. Store leftovers in an airtight container.
