Ingredients
Scale
- one (11.2–12-ounce (330–355ml) bottle guinness draught stout beer
- 3/4 cup (12 tbsp; 170g) unsalted butter
- two 4-ounce bars (226g) semi-sweet chocolate, coarsely chopped
- 1 and 1/4 cups (250g) granulated sugar
- 3 large eggs, at room temperature
- 1 teaspoon pure vanilla extract
- 1 cup (125g) all-purpose flour (spooned & leveled)
- 1/2 teaspoon salt
- optional: 1/2 teaspoon espresso powder
- 1/2 cup (8 tbsp; 113g) unsalted butter, softened to room temperature
- 2 cups (240g) confectioners’ sugar
- 2-3 tablespoons reduced guinness (from step 1)
- 1 teaspoon espresso powder
- 1/2 teaspoon pure vanilla extract
- 1/4 teaspoon salt
Instructions
- Bring the Guinness to a boil in a small saucepan. Reduce heat to medium and simmer until it reduces down to 2/3 cup, about 12-15 minutes. Cool for at least 10 minutes.
- Preheat the oven to 350°F (177°C). Grease a 9-inch square baking pan or line it with foil or parchment, leaving overhang for easy removal. Set aside.
- Melt the butter and chopped chocolate in a microwave-safe bowl in 30-second increments, mixing until smooth. Add sugar and 1/2 cup of reduced Guinness, combine well. Mix in the eggs and vanilla, then add flour, salt, and espresso powder until thick and shiny. Pour the batter into the prepared pan.
- Bake for 32 minutes. Test with a toothpick; if it comes out wet, continue baking for another 2 minutes and check again, usually taking about 35 minutes total.
- Let brownies cool completely in the pan on a cooling rack before frosting.
- Beat the softened butter until creamy. Gradually add confectioners' sugar while mixing, then add 2 tablespoons of reduced Guinness, espresso powder, vanilla extract, and salt. Adjust with more reduced Guinness if necessary.
- Lift the brownies out using parchment overhang. Spread frosting over the top, then cut into squares and enjoy. Store leftovers at room temperature for up to 1 week.
Notes
Ensure the Guinness is reduced properly for the best flavor in the brownies and frosting.
Allow the brownies to cool completely for cleaner cuts when slicing into squares.
Feel free to adjust the amount of espresso powder in the recipe to taste.
