Ingredients

Scale
  • 6 ounces bittersweet or semisweet chocolate, chopped
  • 1/2 cup Guinness stout (room temperature)
  • 3/4 cup unsalted butter, cut into pieces
  • 1 cup granulated sugar
  • 3 large eggs, room temperature
  • 1/2 cup unsweetened cocoa powder
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 4 ounces bittersweet chocolate, chopped (for ganache)
  • 1/4 cup heavy cream
  • 2 tablespoons Guinness stout (for ganache)
  • 1 tablespoon unsalted butter (for ganache)

Instructions

  1. Preheat oven to 350°F (175°C). Grease an 8-inch springform pan with butter and dust with cocoa powder. Set aside. Bring eggs to room temperature.
  2. Melt chopped chocolate and butter together in a heatproof bowl over simmering water until smooth and glossy. Remove from heat and cool slightly.
  3. In a medium bowl, whisk Guinness stout and granulated sugar until sugar dissolves.
  4. Add the cooled chocolate-butter mixture to the Guinness and sugar mixture. Stir in vanilla extract and salt.
  5. Lightly beat eggs in a separate bowl. Gradually whisk eggs into the chocolate mixture, folding gently until smooth and homogenous.
  6. Sift cocoa powder over the batter and fold in carefully. If batter is too stiff, add a tablespoon of stout to loosen.
  7. Pour batter into prepared pan. Bake 30-35 minutes until edges are set but center jiggles slightly when shaken.
  8. Cool cake completely in pan on a wire rack. Once cool, release springform sides and transfer cake to serving plate.
  9. Heat heavy cream in a small saucepan until just simmering. Pour over chopped bittersweet chocolate in a heatproof bowl. Let sit 2-3 minutes, then whisk until smooth.
  10. Stir in Guinness stout and butter until ganache is glossy and combined. Cool slightly to thicken.
  11. Pour ganache over cake, letting it drip down sides. Chill 15-20 minutes for firmer ganache or serve immediately for a soft finish.

Notes

Use room temperature eggs to prevent curdling. Avoid overbaking to keep cake fudgy. Use high-quality bittersweet chocolate for best flavor. For dairy-free, substitute butter with coconut oil and heavy cream with coconut cream. Ganache consistency can be adjusted by warming or chilling as needed.
