Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and prepare two 8-inch round cake pans.
- In a large mixing bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt.
- In a separate bowl, blend sour cream, vegetable oil, eggs, vanilla, and Guinness until smooth.
- Pour the wet mixture into the dry ingredients and mix gently.
- Divide the batter between the two pans, smooth the tops, and bake for 35-40 minutes.
- Cool the cakes for 30 minutes in their pans, then transfer to a wire rack to cool completely.
- Beat the unsalted butter until fluffy, then gradually add powdered sugar and Irish cream.
- Level the top of the cooled cakes if necessary, place one layer on a serving plate, and spread buttercream on top.
- Spread a thin layer of buttercream over the entire cake for a crumb coat, then chill for 30 minutes.
- Frost the top and sides of the cake with the remaining buttercream.
- Heat heavy cream until simmering, pour over chopped chocolate, and stir until smooth to prepare ganache.
- Drizzle ganache over the chilled cake and add sprinkles or chocolate curls if desired.
