Chocolate Frosted Yellow Cake

This is my ALL TIME favorite b-day cake!! I know you're not supposed to eat cake on the regular, but this is the one that gets me every time and it's a blast to make from scratch... So many fun textures to play with during the process and lots of spatulas to lick along the way as well. This is a must try recipe for your next b-day extravaganza.
