Ingredients
- 1 cup Guinness beer: Adds a unique depth of flavor and moisture to the cake.
- 1 3/4 cups all-purpose flour: The base of the cake structure, providing stability and softness.
- 3/4 cup unsweetened cocoa powder: Delivers rich chocolate flavor without added sweetness.
- 2 cups granulated sugar: Sweetens the cake and balances the bitterness of the cocoa.
- 1 1/2 teaspoons baking powder: Helps the cake rise and maintain a light texture.
- 1/2 teaspoon baking soda: Works with the acidity of the Guinness to create lift.
- 1 teaspoon salt: Enhances the flavors and balances sweetness.
- 2 large eggs: Provides moisture, richness, and structure to the cake.
- 1/2 cup unsalted butter, melted: Adds richness and flavor to the batter.
- 1/2 cup sour cream: Contributes to the cake’s moistness and tangy flavor.
- 1 teaspoon vanilla extract: Enhances the overall flavor profile.
- 1 cup heavy cream (for frosting): Creates a creamy, luscious texture in the frosting.
- 1/2 cup powdered sugar (for frosting): Sweetens the frosting while adding a smooth consistency.
- 1 cup Irish cream liqueur (for frosting): Infuses a delicious creaminess and flavor into the frosting.
- 1/2 cup unsalted butter, softened (for frosting): Adds richness and helps create a fluffy texture in the frosting.
Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and grease and flour a cake pan to prevent sticking.
- In a large bowl, whisk together the Guinness beer and melted butter until combined. Stir in the granulated sugar, eggs, and sour cream until the mixture is smooth and well blended.
- In a separate bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Gradually incorporate this dry mixture into the wet ingredients, mixing until just combined. Do not overmix.
- Pour the batter into the prepared cake pan and bake for 30-35 minutes. The cake is done when a toothpick inserted into the center comes out clean.
- Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
- For the frosting, beat the softened butter in a large bowl until creamy. Gradually add the powdered sugar, mixing until fluffy. Then, mix in the Irish cream and heavy cream until the frosting is smooth and well combined.
- Once the cake is completely cooled, frost the top and sides generously with the Irish buttercream. Slice, serve, and enjoy!
