In this video tutorial I show you how to pipe multiple colours on to cupcakes. It is a lot easier than you may think and it looks so pretty.
You will need some vanilla cupcakes or other cupcakes of your choice or cake. There are a few recipes to browse and choose from on this website
Make some buttercream of your choice, I used American buttercream but you can use Swiss Meringue buttercream or Italian Meringue buttercream.
Colour it with some gel colours
Pipe strips of the colours in cling film, roll it tightly and then cut one end, put in piping bag. Watch video for an illustration.
