I made this cake for my son's birthday a couple weeks ago. I create invitations and wanted his cake to match the invitation I had designed for him. I was worried about how the palm trees would look as a "silhouette". I should have worried more about the waves, because they gave me a really hard time! : ) Top layer is chocolate cake, bottom layer is vanilla cake. Both covered in buttercream icing with fondant accents. "Sand" is crushed vanilla wafers. Wish I would have crushed them more - was rushed.
