I made this cake for my daughter's 3rd birthday last month - she loves mermaids at the moment. The water is made from a large lamington sized chocolate cake cut in tw covered with chocolate buttercream ,draped with blue fondant. The sand is crushed biscuits. The rock is a pudding bowl chocolate cake carved into a rock shape and covered with buttercream. The mermaid is made from fondant and the torso and head are modelling fondant. The seahorses are made from granulated sugar pressed into a sandpit mould
