How to Make Chocolate Guinness Cake
Ingredients:
- 1 cup Guinness stout
- 1 ½ cups granulated sugar
- ¾ cup cocoa powder (not Dutch process)
- ¾ cup vegetable oil
- 2 large eggs
- ¼ cup sour cream
- 1 tablespoon vanilla extract
- 2 cups all-purpose flour
- 2 teaspoons baking soda
- 1 teaspoon salt
- 16 ounces semi-sweet chocolate (about 3 cups)
- 1 cup heavy cream
- ½ cup Guinness
- 6 tablespoons salted butter (softened)
- 1 ½ cups powdered sugar
- 4-5 tablespoons Bailey’s Irish Cream
Directions:
- Cake: Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans. In a bowl, mix the Guinness, sugar, cocoa powder, and vegetable oil. Then add eggs, sour cream, and vanilla extract. In another bowl, whisk together flour, baking soda, and salt. Combine the wet and dry ingredients until smooth. Divide the batter between the prepared pans and bake for 25-30 minutes. Let cool.
- Ganache: Heat the heavy cream in a saucepan until just simmering. Pour the hot cream over the chopped semi-sweet chocolate in a bowl. Let it sit for a few minutes, then stir until smooth.
- Bailey’s Buttercream Filling: In a bowl, beat the softened butter until creamy. Add powdered sugar, Bailey’s Irish Cream, and mix until fluffy.
- Assembly: Once the cakes have cooled, place one layer on a serving plate. Spread the Bailey’s buttercream on top, then place the second layer on top. Pour the chocolate ganache over the cake, letting it drip down the sides.
