Chill for about 30 minutes to set the buttercream. Place the pink buttercream into a large piping bag fitted with a large star nozzle. Pipe swirls of pink buttercream all over the top of the cake.

You can use any color of sprinkles to fill the inside of the cupcakes, I used a pink mix to keep with the theme of pinks and reds. Mini M&M’s are also a great idea to use for the pinata filling.
