This cake was so much fun to design. I love that it is girly yet colorful and fun. After covering the cakes in white fondant, I used my airbrush to color the tiers this pretty teal and blue-green underwater color. I made the figures out of gum paste because it dries harder and more quickly than fondant. Once they were dry, I attached them to the cake using royal icing. I used the same royal icing to pipe tiny bubbles around the cake.
I added the number 4 to a cute starfish I made using a silicone mold. The seashells were also made using silicone molds. I think they were one of the first molds I ever bought and they always come in handy! I cut the purple seaweed freehand out of thin fondant and just twisted them a bit. They give the cake some life, movement, and texture. They also make the cake look super cute! Happy 4th Birthday Libby!
