  • 12 oz semisweet chocolate, chopped
  • 14 tbsp unsalted butter
  • 1/2 cup stout beer
  • 1/2 cup granulated sugar
  • 1/4 tsp salt
  • 6 eggs
  • 1/4 cup unsweetened cocoa powder, divided
  • 1/2 tsp instant espresso powder


  • Preheat oven to 300 degrees F. Butter the bottom and sides of a 9" springform pan, and sprinkle 1 tbsp of cocoa powder over bottom and sides. Shake the pan until the cocoa powder coats the buttered areas, discarding any excess loose powder.
  • Add chocolate and butter to a microwave-safe bowl and microwave in 20 second intervals, whisking well after each interval, until melted and smooth. Set aside to cool slightly.
  • In a mixing bowl, whisk together stout, sugar, and salt. Add eggs and whisk until combined.
  • Pour a small drizzle of the melted chocolate/butter mixture into the bowl with the egg mixture as you whisk constantly. Go very slowly as to not cook the eggs. Continue pouring the chocolate/butter into the egg mixture until everything is combined, whisking the entire time.
  • Whisk in the unsweetened cocoa powder and instant espresso powder.
  • Pour batter into prepared pan and bake for 45 or so minutes, or until the edges have set and a toothpick inserted into the center comes out mostly clean. Let cool completely in the pan set on a wire rack. Dust with confectioners' sugar or cocoa powder before serving. This cake is best stored in the refrigerator and enjoyed cold!
