I am afraid we made a bit of a mess with the green icing. But we thought it would still give you some ideas for decoration. The cake is the same recipe that we used for the football birthday cake (http://www.mumandsons.com/2014/02/kids-birthday-cake.html) It is indeed a very versatile cake-base. We have cut it into two layers and used buttercream - this helps to keep it moist so that you can prepare it the day before the birthday takes place. The figures are done with shop bought icing - it is a bit fiddly for the children, but at the end of the day it is like playing with plasticine.
