Ingredients

• 2.75 cups butter
• 0.75 cups unsweetened cocoa powder
• 1 cup Irish stout beer , such as Guinness Extra Stout
• 1 tablespoon vanilla extract
• 2.75 cups all-purpose flour
• 1 teaspoon baking soda
• 1 teaspoon baking powder
• 0.25 teaspoons salt
• 4 cups white sugar
• 2 eggs

Instructions

1. 1 Preheat the oven to 350 degrees F (175 degrees C). Grease 66 mini muffin cups or line with paper liners.
2. 2 Make the cupcakes: Melt butter in a saucepan over low heat. Add cocoa powder and whisk until smooth. Stir in beer and vanilla extract. Remove from the heat and let cool, 5 to 10 minutes.
3. 3 Sift flour, baking soda, baking powder, and salt into 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.
4. 4 Bake in the preheated oven until tops spring back when lightly pressed, 10 to 11 minutes. Cool in the tins for 5 minutes, then transfer to a wire rack and let cool completely, about 20 minutes.
5. 5 Meanwhile, make the frosting: Beat confectioners' sugar and butter in a bowl with an electric mixer. Add Irish cream liqueur, 1 tablespoon at a time, and beat until light, fluffy, and white in color, about 10 minutes.
6. 6 Spread frosting over cooled cupcakes.
