Make the perfect St. Patricks Day Rainbow cupcakes or use them for a rainbow themed party. They're so fun!
Make the cupcakes according to the package instructions. Scoop out a tablespoon at a time into each cupcake liner. Try and keep the colors as smooth of a transition as possible and try not to let the colors bleed into one another.
Allow the cupcakes to cool completely before frosting them.
Use a large, round tip and a piping bag to get a smooth finish on your buttercream.
Top with gold coins and maybe gold sprinkles!
