Apparently rainbow cake in some form has become a St. Patrick's Day tradition in our house. We've made mini versions and the more classic version so this year I wanted to finally make this take on the rainbow cake that I have admired for some time...The leprechaun trap cake featured here. Since Clementine had already created her own leprechaun trap (and let's be honest, I really didn't have the time or energy to make it as beautiful as the recipe showed) I decided to just use the technique for the rainbow cake and frost it in simple white buttercream with festive nonpareils and shamrocks. Probably my favorite part of this is it is baked all together in one pan. It wasn't perfect but it was fun!
