I was asked to make a 30th birthday cake only using the colours white, black and red. I cheated a wee bit and added a touch of silver and it all looks lovely. I made the '30' explode out of the cake by splitting the top of the cake and peeling it back. Also I put a cascade of different sized stars pouring down the side. It has turned out well and looks like a 'party in a cake', which is what the customer wanted.
