Instructions

Preparation

  • Preheat the oven to 350°F (175°C). Prepare two 8-inch round cake pans by greasing and lining them with parchment paper.
  • In a medium saucepan, combine the Guinness and cubed butter over medium heat. Stir until the butter is melted. Incorporate the cocoa powder and granulated sugar, whisking until smooth. Allow the mixture to cool slightly.
  • In a large mixing bowl, whisk together the sour cream, eggs, and vanilla extract. Gradually blend in the cooled Guinness-chocolate mixture.
  • Sift in the all-purpose flour and baking soda. Gently fold until just combined.

Baking

  • Divide the batter evenly between the prepared cake pans. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
  • Let the cakes cool completely in the pans on a wire rack.

Buttercream Preparation

  • Beat the room temperature butter using an electric mixer until fluffy. Gradually add the powdered sugar one cup at a time, beating well after each addition.
  • Mix in the Baileys Irish Cream and a pinch of salt until creamy and smooth.

Assembly

  • Once the cakes are cool, spread a generous layer of Baileys buttercream between the layers and cover the top and sides of the cake.
  • Decorate with green and gold sprinkles or chocolate shavings if desired.

Notes

Use room temperature ingredients for a smoother batter and avoid opening the oven door during baking to prevent the cake from sinking. The recipe can be doubled for larger gatherings.
