I made this cake for my Son’s first birthday. We used 10 inch, 8 inch, and 6 inch pans, Layering them using cardboard support.
We used store bought vanilla frosting and colored it with coloring gel. After icing the cake we used toothpicks to swirl the frost. Making it look like water. we used chocolate rock candies for the bottom. And I made shells with chocolate and molds.
I also made the under water plants by piping colored chocolate onto wax paper. After letting all the chocolate cool, peel from the wax paper and gently stick into the frosting.
We finished the cake by sprinkling colored sugar over the top.
