Found this on a site called "Mother Thyme" and as Coconut cake is my favorite decided to save. She states "The secret ingredient in the cake and the frosting is coconut cream instant pudding mix. I admit, I have an obsession with using pudding mix in many of my desserts. The coconut cream pudding mix gives both the cake and the frosting a great flavor with just the right amount of coconut in each tasty bite. If you want to get a little fancy and layer this cake, simply double the recipe. If you double the frosting, you will have extra leftover after you fill and frost the cake, but leftover frosting is never a bad thing.
