Bachelor Party & Birthday Cake This was a cake I was asked to do for two occasions, I was just asked to do a cake for a birthday and a stag party. I didnt have a clue what theme to do, but didnt want to do a rude cake, so opted for this one. The model is just bought and make the L plates from sugar paste. the ball and chain is made from fondanat as the decorative balls around the cake. The cake is vanilla sponge with jam and buttercream.
