Chocolate Guinness® Cupcakes With Irish Cream Frosting

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease 3 mini-muffin tins or line cups with paper liners; this recipe makes about 66 mini cupcakes.

Step 2
Melt 1 1/4 cups butter in a saucepan over low heat, add cocoa powder, and whisk until smooth. Stir in beer and vanilla extract. Remove from heat and allow to cool.

Step 3
Combine flour, baking soda, baking powder, and salt and sift into in a large bowl. Mix in sugar. Add beer mixture and stir until thoroughly combined. Add eggs, stirring until well incorporated. Spoon batter into the prepared mini-muffin cups, filling each 3/4 full.

Step 4
Bake in the preheated oven until tops spring back when lightly pressed, 10 to 11 minutes. Cool in the tins for 5 minutes. Transfer to a wire rack and let cool, about 20 minutes.

Step 5
Beat 1 1/2 cups butter and confectioners' sugar in a bowl using an electric mixer. Add Irish cream liqueur, 1 tablespoon at a time, and beat until light, fluffy, and white in color, about 10 minutes. Top cooled cupcakes with frosting.
