Skittles Cupcakes with Rainbow Icing (RECIPE + VIDEO TUTORIAL)

skittles cupcakes with ice

The rainbow icing is a beautiful way to decorate any flavour of cupcake.  “I thought the bright, vibrancy of the buttercream would pair perfectly with Skittles, because, as I mentioned already, the Skittles slogan isTaste the Rainbow.”  Striping the bag is the easiest way to achieve this effect.

It is simple, and produces a beautiful, rainbow topping. Adding a couple of Skittles to the top for decoration, completes the Skittles theme of the cupcakes.
