For an adults-only treat, try these chocolate beer cupcakes with whiskey filling and Irish cream icing. While they would be the perfect things to serve on St. Patrick’s Day, they also work well with barbecues, wedding showers and other adult parties. The filling is made from mixing whiskey and melted butter together, and the frosting is a buttercream that also contains Irish cream liquor. The cupcakes themselves have stout beer in them, turning these treats into a festival of fun!
