Okay, I'm going to bake a simple Victoria sponge cake then cover it with white glace icing before I pipe Mr Strong (his favourite character~) on it with a birthday message. Now I've got a piping kit and I know how to pipe chocolate using greaseproof paper but I would like to do this in colour. I know that you can get icing pens from supermarkets but I would like to make it instead. What's the recipe for this sort of icing to pipe the outline of the character. Also, how does one colour in the character? Or do I need to buy one of those roll out icings then colour it in red?
any help would be very much appreciated thank you!
