Pizza cake

It is Sev's 19th birthday tomorrow and I wanted to make a "pizza" cake. I saw this decoration for a cake in a cookery book at Andy's mum's house. As Sev likes pizza I thought it would be a fun thing to do. So I made a some small cakes yesterday to trial out the decoration. I made these with icing sugar and water mix, but today when I made the bigger pizza cake, I used butter icing which gives a better finish, I think.

Hope he likes it.
