Can you ever have enough recipes for Chocolate Cake? I don't think so. Here's another Retro recipe from the 70s from Hershey's for Hershey's Prize Chocolate Cake. This recipe uses cocoa, and, of course, specifically Hershey's cocoa. If you have a cocoa you favor, feel free to use it instead. And, don't miss the note: How to Bake with Cocoa. FYI, I usually decrease the amount of sugar in this recipe.
