Ingredients

1 cup Guinness beer: This stout enhances the chocolate flavor and adds moisture.
1 3/4 cups all-purpose flour: Gives the cake structure and supports its height.
3/4 cup unsweetened cocoa powder: Deepens the chocolate flavor without added sugar.
2 cups granulated sugar: Provides sweetness and helps create a tender crumb.
1 1/2 teaspoons baking powder: Acts as a leavening agent for a light texture.
1/2 teaspoon baking soda: Works with the acidic ingredients to create a fluffy cake.
1 teaspoon salt: Enhances the overall flavor profile of the cake.
2 large eggs: Binds the ingredients together and adds richness.
1/2 cup unsalted butter, melted: Adds moisture and a rich buttery flavor.
1/2 cup sour cream: Keeps the cake moist and adds a slight tang.
1 teaspoon vanilla extract: Boosts the sweetness and adds depth to the flavor.

For the frosting:

1 cup heavy cream: Creates a rich and creamy buttercream.
1/2 cup powdered sugar: Sweetens the frosting and helps achieve the right consistency.
1 cup Irish cream liqueur: Infuses the frosting with a delightful flavor.
1/2 cup unsalted butter, softened: Adds creaminess and holds the frosting together.

Step-by-Step Instructions

Preheat your oven to 350°F (175°C). Grease and flour a cake pan to ensure easy removal after baking.
In a large bowl, whisk together the Guinness beer and melted butter until well combined. Add in the granulated sugar, eggs, and sour cream, stirring until smooth and fully mixed.
In a separate bowl, combine the all-purpose flour, cocoa powder, baking powder, baking soda, and salt. Stir together thoroughly to blend the dry ingredients.
Gradually add the dry mixture to the wet mixture, stirring gently until just combined. Be careful not to overmix, as this can affect the cake’s texture.
Pour the batter into the prepared pan, spreading it evenly. Bake in the preheated oven for 30 to 35 minutes, checking for doneness with a toothpick.
Once baked, allow the cake to cool in the pan for about 10 minutes. Then transfer it to a wire rack to cool completely.
To prepare the Irish buttercream, beat the softened butter in a mixing bowl until creamy. Gradually add the powdered sugar and beat until fluffy. Mix in the Irish cream and heavy cream until the frosting is smooth and well combined.
Once the cake has cooled completely, generously frost the top and sides of the cake with the Irish buttercream. Slice, serve, and enjoy!
