How to Make Guinness Brownies
Phase 1 – Prep
STEP 1. Reduce the Guinness. In a small saucepan, bring the Guinness to a boil over medium-high heat. Once boiling, reduce to medium heat and allow to simmer until reduced down to 2/3 cup, about 20-22 minutes. Set aside to cool for at least 10 minutes. You will use 1/2 cup in the brownies and the rest in the frosting.
STEP 2. Preheat the oven. Preheat the oven to 350°F (177°C) and grease a 9-inch square baking pan or line with aluminum foil or parchment paper, leaving an overhang on the sides to lift the finished brownies out. Set aside.
Phase 2 – Cook
STEP 3. Melt butter and chocolate. Place the butter and chopped chocolate in a large microwave-safe bowl. Melt in 30-second increments, whisking after each, until completely smooth.
STEP 4. Combine the batter. Whisk in the sugar and 1/2 cup of reduced Guinness until completely combined. Whisk in the eggs and vanilla extract. Finally, whisk in the flour, salt, and espresso powder (if using). The batter will be thick and shiny. Pour/spread evenly into prepared pan.
STEP 5. Bake the brownies. Bake for 32 minutes, then test the brownies with a toothpick. Insert it into the center of the pan. If it comes out with wet batter, the brownies are not done. If there are only a few moist crumbs, the brownies are done. Keep checking every 2 minutes until you have moist crumbs.
STEP 6. Cool the brownies. Remove from the oven and place on a wire rack to cool completely before frosting or cutting into squares.
Phase 3 – Serve
STEP 7. Make the frosting. In a large bowl using a handheld or stand mixer fitted with a whisk attachment, beat the butter on high speed until completely smooth and creamy, about 2-3 minutes. Add the confectioners’ sugar, beating on low at first then increasing to high speed.
STEP 8. Finish the frosting. Once creamy and combined, beat in 2 Tablespoons of reduced Guinness, the espresso powder, vanilla extract, and salt. Taste. Add the remaining reduced Guinness if needed. If you want the frosting a little thinner, add a splash of milk.
STEP 9. Frost the brownies. Frost cooled brownies. Cover and store leftover brownies at room temperature for up to 1 week.
Why This Recipe Works
This brownie recipe achieves a perfect texture balance between fudgy and chewy due to the combination of butter, chocolate, and eggs. The reduced Guinness complements the chocolate, enriching the flavor without overpowering it. Each ingredient interacts seamlessly: the sugar adds sweetness, while the flour provides structure and the butter ensures moisture. The use of espresso powder (if chosen) also heightens the chocolate flavor, creating a multidimensional tasting experience. The baking method helps lock in moisture while allowing the edges to achieve a slight crispness, making these brownies enticingly delicious.
Pro Tips
To ensure your Guinness brownies turn out perfectly, consider these tips:
- Use quality chocolate: High-quality semi-sweet chocolate enhances the flavor significantly.
- Do not overmix: Mix the batter just until combined to keep the brownies fudgy.
- Test for doneness accurately: Use a toothpick and look for moist crumbs, not wet batter.
- Let them cool: Allow the brownies to cool completely before frosting for the best texture.
- Experiment with flavors: Try adding nuts or different flavored extracts for a unique twist.
