Carefully stripe up the side of a piping bag, three to four colors works best, and fill the center with white. Pay close attention when putting the colors into a pattern or they will gray tone. Once the bag is ready, you can pipe the icing onto the cupcakes with an even balance of the four colors.
Next, add a finishing touch of edible glitter on top of each cupcake. With this final feature, the cupcakes will sparkle under a bakery case light, attracting attention and hungry eyes.
