For Frosting

  • Cream shortening and butter with electric mixer. Add peanut butter and vanilla. Gradually add sugar, one cup at a time, beating well on medium speed. Scrape sides and bottom of bowl often. When all sugar has been mixed in, icing will appear dry. Add milk, one tablespoon at a time, and beat at medium speed until light and fluffy. Fill large pastry bag with a large star tip for decorating or you can fill a ziplock bag with frosting and cut off corner of bag. Pipe frosting onto cupcakes.

For Ganache

  • Heat the cream and corn syrup till they begin to steam. Pour over the chopped chocolate in a bowl. Let sit for 5 minutes, and whisk until smooth. Allow to cool until ganache starts to thicken then drizzle over cupcakes and decorate with additional mini peanut butter cups
