My brother's nickname is Matty Moo so for his 21st Birthday we made him a cow cake! It was really simply, the cow was really easy and looked great. The 2 and 1 were just tins I hired and covered with butter icing (made with Solite to make sure it stayed white) and the black patches were made from fondant icing.
I made the cow with two oven proof bowls, cut them to shape and covered with black and white fondant (it's really easy to use and shape). The candles were from spotlight and gave the final product some color.
Honestly, this cake looked good but was really easy to do.
