Serve up something sweet and light at your next St. Patrick’s Day party – these Guiness Stout Cupcakes! Yes, the batter contains 1 and a half cups of Guiness Stout, as well as more traditional staples like flour, sugar, cocoa powder and eggs, among other things. Following the theme, the frosting contains alcohol as well — Irish Cream — made into a buttercream frosting, thanks to the addition of butter and sugar. Top each with a sprinkle of sugar (or green sprinkles) and a plastic four-leaf clover to set the mood.
