The Rainbow cake!!

This was actually my friend Anna's idea... she was modelling for the recent Jigsaw campaign and it happened to be the stylists birthday on the first day of the shoot.. so we made this as a surprise.

This makes two cakes, this is because you must slice each cake in half otherwise it will be a mountain.. you can freeze the second one, or just give it away, a kind deed for the day...

550g soft margarine
