Ingredients

Units Scale

Guinness Brownies

  • 1/4 cup vegetable oil
  • 3/4 cup Guinness Stout beer
  • 2 cups sugar
  • 1/2 teaspoon espresso powder (optional)
  • 1/2 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 1/4 cup unsalted butter, melted
  • 2 large eggs
  • 1 cup all-purpose flour
  • 2/3 cup Dutch-processed cocoa powder

Chocolate Topping

  • 5 ounces semi-sweet chocolate chips (about 2/3 cup)
  • 2 tablespoons unsalted butter
  • 2 tablespoons Guinness Stout beer
  • 1/4 cup powdered sugar

Instructions

  1. Preheat oven: Preheat your oven to 350°F (180°C). Grease a 9x9 inch square baking pan and line it with parchment paper hanging over the sides to help remove the brownies later.
  2. Mix wet ingredients: In a large mixing bowl, whisk together vegetable oil, Guinness Stout beer, sugar, espresso powder if using, vanilla extract, and salt until well combined.
  3. Add butter: Pour in the melted unsalted butter and whisk until fully incorporated.
  4. Add eggs: Add the eggs one at a time, whisking after each addition until the mixture is smooth.
  5. Incorporate dry ingredients: Gently whisk in the all-purpose flour and Dutch-processed cocoa powder just until combined—do not overmix.
  6. Bake the brownies: Pour the batter into the prepared pan and spread evenly. Bake for 30 minutes or until a toothpick inserted comes out with a few moist, sticky crumbs.
  7. Cool: Allow the brownies to cool completely in the pan on a wire rack.
  8. Make chocolate topping: In a microwave-safe bowl, combine the semi-sweet chocolate chips, unsalted butter, and Guinness Stout beer. Microwave in 30-second intervals until the mixture is hot and the butter begins to melt, whisking until smooth. Add powdered sugar and whisk until smooth and well combined.
  9. Apply topping: Pour the ganache over the cooled brownies and spread into an even layer.
  10. Set and serve: Let the brownies cool completely until the topping is set. Use the parchment overhang to lift brownies from the pan and cut into bars.
  11. Storage: Store brownies in an airtight container. Keep at room temperature for up to 2 days, then refrigerate due to the topping. Best consumed within 4-5 days.

Notes

  • For a deeper chocolate flavor, use Dutch-processed cocoa powder as indicated.
  • Espresso powder is optional but enhances the chocolate flavor wonderfully.
  • Make sure not to overmix the batter to keep the brownies tender.
  • Use parchment paper to easily lift the brownies out of the pan for cleaner cuts.
  • Store brownies refrigerated after 2 days to maintain freshness, especially because of the ganache topping.
  • Let ganache set fully at room temperature before slicing for clean slices.
