My husband is obsessed with Oreo Cakesters and wants a birthday cake that is essentially a giant Oreo Cakester. It's easy to find chocolate cake and vanilla filling recipes that I could craft into a giant Oreo, but most chocolate cakes don't actually have that unique Oreo taste. Does anyone have a recipe for a chocolate cake that tastes like an Oreo, or an Oreo Cakester? And filling suggestions? Thanks!
