My nephew asked me to make him this Rolling Stones cake for his 13th birthday. I took a picture of the tongue and blew it up on a photocopier, cut it out and placed it on the cake. I then traced around the cake with a knife and cut out the shape.
I cut out the teeth and the other shapes on the cake and put them on the cake and traced around them with a toothpick. Slowly I piped in all the shapes and did the red last. The red frosting was very difficult to make.
