For this first birthday cake I started with a half sheet of marble cake, froze the cake overnight to make cutting it out easier. Then I drew a quick paper pattern of a large number “one” that used up most of the cake and layed it onto the cake.
Next I cut the cake in the shape of the pattern with a sharp knife while the cake was still frozen. I frosted it with homemade buttercream frosting and also added blue coloring to a small batch to make the decorative features. The fish, turtle, and shark are gummies, and the bubbles are spots of the blue frosting.
I am not a cake maker by any means, but I am a loving father of his first child. My wife and some of her family didn’t believe me when I said I was going to make my son’s first cake!
