My friend's middle daughter wanted a mermaid cake for her birthday party this year. I was happy to fulfil her request. There were a few issues surrounding party days but in the end the cake turned out really well and the birthday girl loved it and that is what is important.
Cake is the usual chocolate cake made in two 20 cm cake tins and filled with a chocolate cream cheese filling. Covered in butter cream with fondant decorations. The "sand" on the board is crushed biscuits.
