This four-layer chocolate cake with buttercream icing sits on top of some wooden crates that have been draped with a fishing net. Faux seaweed, starfish and shells surround the cake and help to complete the nautical look. The cake is garnished with a chocolate lighthouse, chocolate shells, sand made from brown sugar and a pennate that matches the larger one hanging in the party space. Nautical birthday party.
