Ingredients

The following ingredients have 8 Servings
  • 1 cup dark beer (such as stout)
  • 8 tablespoons unsalted butter
  • 1/2 cup + 1 tablespoon unsweetened cocoa powder
  • 1 cup + 2 tablespoons granulated sugar
  • 2 ounces unsweetened chocolate, chopped
  • 1 large egg white
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon fine sea salt
  • 1/2 cup all-purpose flour
  • 6 tablespoons unsalted buter, softened
  • 1 cup powdered sugar

Instruction

  • Add the beer to a small saucepan and boil until it reduces to 1/3 cup. It will take about 20 minutes. Keep an eye on it to prevent it from boiling over.
  • Preheat the oven to 325°F and line a loaf pan with parchment paper.
  • In a microwave-safe bowl, combine the butter, cocoa powder, sugar, and unsweetened chocolate. Microwave on full powder for 30 seconds. Stir, then microwave for another 30 seconds. Let the mixture cool for 1 minute.
  • Stir in 4 tablespoons of the beer concentrate, the egg white, vanilla, and salt.
  • Finally, mix in the flour and stir for 50 strokes to incorporate and activate the gluten in the flour.
  • Pour the mixture into the loaf pan and bake for 40-45 minutes. It’s done when the surface is dry and an inserted toothpick has only moist crumbs sticking to it. Let cool.
  • Once the brownies are cool, make the frosting. Beat together the softened butter and powdered sugar until combined. Beat in the remaining beer concentrate (1 tablespoon).
  • Frost the brownies and serve.
