Guinness Stout Brownies Recipe — Rich Chocolate Guinness Brownies

This is an older favorite I’m keeping because I definitely want to make these brownies again. They are Guinness Stout Brownies — rich, chocolatey, and similar in texture to one of my go-to brownie recipes but with the addition of stout for depth. I’m planning to bake them again soon and update the photo. I’ve also wondered whether a light, fluffy white frosting might complement them, though they’re delicious as-is.

Guinness Stout Brownies Notes

From my previous notes: the Guinness flavor isn’t overpowering — it adds a subtle, malty complexity rather than a strong beer taste. If you prefer a more pronounced stout note, reduce the chocolate slightly or use a bolder stout.

Ingredients

  • 1 cup all-purpose flour
  • ¾ cup unsweetened cocoa powder (I used a mix of dark and natural)
  • ¼ teaspoon salt
  • 6 tablespoons unsalted butter, room temperature cut into cubes
  • 8 ounces dark bittersweet chocolate chopped
  • ¾ cup white chocolate chips
  • 4 large eggs at room temperature
  • 1 cup superfine or granulated sugar
  • 1-¼ cups Guinness Extra Stout (10 oz), room temperature
  • ¾ teaspoon vanilla extract
  • 1 cup semi-sweet chocolate chips
  • cup confectioners’ sugar, for dusting (optional)

Instructions

  • Preheat the oven to 375°F (190°C). Line a 9 x 13-inch baking pan with nonstick foil or parchment and set aside.
  • In a medium bowl, whisk together the flour, cocoa powder, and salt until well combined. Set aside.
  • Melt the butter, bittersweet chocolate, and white chocolate chips together using a double boiler over very low heat, stirring until smooth. Alternatively, microwave in short bursts on high, stirring every 30 seconds until melted. Remove from heat.
  • In a large bowl, beat the eggs and sugar on high speed until light and fluffy, about 3 minutes. Fold in the melted chocolate mixture until combined.
  • Add the reserved flour mixture and mix gently until incorporated. Whisk in the room-temperature Guinness and vanilla — the batter will be somewhat thin. Evenly scatter the semi-sweet chocolate chips on top; some will sink into the batter.
  • Pour the batter into the prepared pan and bake on the center rack for 25 to 30 minutes, or until a toothpick inserted near the center comes out with just a few moist crumbs.
  • Allow the brownies to cool completely in the pan, uncovered. Dust with confectioners’ sugar before slicing, if desired.
