Last year's attempt to make a pocketbook cake. I made a 9 inch round cake with two layers. The cake was rainbow sprinkle vanilla cake.Then cut 1/4 of the cake to make a flat edge.
Because I decorated the cake the same day as the party, I didn't have time to refrigerate the cakes to set up. After frosting the cake with vanilla frosting, I added rainbow star sprinkles, then piped pink frosting around the edges to simulate ruffles. The handle was made with Twizzlers.
