Below is a shot of the cupcakes right after I filled them with lemon curd. YUM.
8oz. softened cream cheese
Whip butter and cream cheese. Add the rest of the ingredients and mix on medium until light and fluffy. Put the frosting in a piping bag and use a large star tip. Frost each cupcake in a circle, starting at at the outside and working your way inward. Chill for 30 minutes to allow the frosting to set before serving.
