This light and fluffy pokémon cake is a vegan chocolate and vanilla marble cake with buttercream frosting. The cake has both chocolate and vanilla vegan frosting swirled together, and then it’s decorated to look like pikachu. This pikachu cake would be a perfect cake idea for a cute pokemon-themed birthday party, or you can skip the decoration and just make a grown-up marble cake. This marble cake recipe makes a 2-layer 8” or 9” round pikachu marble cake (16 pieces of cake).
