Pretty right? Just wait until you see how easy it is!
You'll want some cupcakes. and some buttercream. and a size 1M wilton decorating tip, with a bag.
I'll describe it first, then there is a video!
Put frosting in the decorating bag with tip. Hold the tip perpendicular to the cupcake in the middle. With even pressure, start piping, and swirl in a circle (I go counter clock-wise), until the whole cupcake is covered. Got it? yeah, I like videos too :)
and there ya go! Good Luck!
