Closed star decorating tip for Beautiful Soft Rainbow Cupcakes


  • Ziploc bags! Use a Ziploc bag to pipe the batter into the cupcake holders, as it is much easier than spooning and spreading each layer.
  • Looking for stunning and perfect white frosting rather use shortening over butter, although, *personal preference*, I think butter tastes better than shortening.
  • Be cautious, DO NOT overbake the cupcakes, as you for sure DO NOT want the tops turning brown.
  • In order to get that perfect and beautiful star, you should use a large closed star decorating tip.
