Guinness Brownies 🍺🍫 Rich, Fudgy, and Deeply Malty

— The Ultimate Boozy Chocolate Treat

These Guinness Brownies are ultra-fudgy, intensely chocolaty, and infused with the deep, roasty notes of stout beer. The Guinness adds richness and complexity to the chocolate, enhancing the flavor without overwhelming it.

Whether you serve them warm with ice cream or chilled with a drizzle of ganache, these brownies are bold, indulgent, and unforgettable.

Ingredients (Makes 9–12 brownies)

• 1 cup Guinness stout (reduce to ½ cup for extra flavor)
• ½ cup unsalted butter (1 stick)
• 8 oz semi-sweet or dark chocolate, chopped
• ¾ cup granulated sugar
• ¼ cup brown sugar
• 2 large eggs
• 1 tsp vanilla extract
• ½ cup all-purpose flour
• ¼ cup unsweetened cocoa powder
• ½ tsp salt
• Optional: ½ cup chocolate chips, walnuts, or flaked sea salt

Instructions

Step 1: Reduce the Guinness

1. In a small saucepan, simmer 1 cup Guinness over medium heat until reduced to ½ cup.
2. Let cool to room temperature.

Step 2: Make the Chocolate Base

1. Preheat oven to 350°F (175°C).
2. Line an 8×8″ baking pan with parchment or grease it well.
3. In a heatproof bowl over simmering water (or in the microwave), melt butter and chocolate, stirring until smooth.
4. Remove from heat and stir in sugars, then eggs, vanilla, and cooled Guinness reduction.

Step 3: Finish the Batter

1. Sift in flour, cocoa powder, and salt.
2. Stir gently until just combined.
3. Fold in chocolate chips or nuts if using.

Step 4: Bake

1. Pour batter into the prepared pan and smooth the top.
2. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
3. Cool completely in the pan before slicing.

Optional Toppings

• Guinness chocolate ganache (melt 4 oz chocolate + ¼ cup warm cream + 1 tbsp Guinness)
• Flaky sea salt sprinkled on top before baking
• Espresso powder (½ tsp in the batter) for mocha depth
• Vanilla ice cream + warm brownie = perfection

Pro Tips

• Reducing the Guinness intensifies the flavor and prevents the batter from being too wet
• Don’t overmix — you want a tender, fudgy crumb
• Store in an airtight container at room temp for 3–4 days, or freeze for up to 2 months
• For gooey brownies, slightly underbake and chill before cutting

Final Thoughts

Guinness Brownies are bold, rich, and perfect for beer lovers, chocolate lovers, and anyone who appreciates a twist on the classic brownie.

The stout brings out the best in the chocolate, making these feel like a pub dessert and a bakery indulgence rolled into one.

Reduce it. Whisk it. Bake the bold. 🍺🍫🔥
