This is a cake I did for a 15 year old girl. It is frosted in butterceam. The zebra stripes were drawn freehand with a toothpick first and then filled in with black buttercream that I patted down with my fingertip (dipped in cornstarch). The bow is made from fondant, as is the 15. I simply used cookie cutters, stuck the numbers on lollipop sticks, and allowed them to harden before putting into the cake.
