Ingredients: 1 cup Guinness Stout. 1 cup unsalted butter. 3/4 cup unsweetened cocoa powder. 2 cups all-purpose flour. 2 cups granulated sugar. 1 1/2 teaspoons baking soda. 3/4 teaspoon salt. 2 large eggs. 2/3 cup sour cream. 1/2 cup Irish cream liqueur. For the Irish Cream Frosting:. 1 cup unsalted butter, softened. 4 cups confectioners' sugar. 1/4 cup Irish cream liqueur. For decoration optional:. Chocolate shavings. Green sprinkles.
Instructions: Preheat your oven to 350F 175C and line a muffin tin with cupcake liners. In a saucepan, heat the Guinness and butter over medium heat until the butter is melted. Remove from heat and whisk in the cocoa powder until smooth. Let it cool slightly. In a large bowl, whisk together the flour, sugar, baking soda, and salt. In another bowl, beat the eggs, sour cream, and Irish cream liqueur together until well combined. Pour the Guinness mixture into the dry ingredients and mix until just combined. Then, fold in the egg mixture until the batter is smooth. Divide the batter evenly among the cupcake liners, filling each about 2/3 full. Bake for approximately 18-20 minutes or until a toothpick inserted into the center comes out clean. Remove from the oven and let the cupcakes cool in the pan for 5 minutes before transferring them to a wire rack to cool completely. For the Irish Cream Frosting, beat the softened butter until creamy. Gradually add the confectioners' sugar and Irish cream liqueur, and continue to beat until the frosting is light and fluffy. Once the cupcakes are completely cool, frost them with the Irish Cream Frosting using a piping bag or a spatula. If desired, decorate the cupcakes with chocolate shavings and green sprinkles. Serve and enjoy your delicious Guinness Irish Cream Cupcakes!
