Today is National Cake Day, and that means Chocolate Cake to me. You know I love these Retro Recipe Ads, and here's a perfect one for Hershey's Prize Chocolate Cake! This recipe uses Hershey's Cocoa, and claims that "108 women baked up their favorite chocolate cake recipe twice..once using baking chocolate as called for, then the identical recipe using Hershey's Cocoa instead... The cakes made with Hershey's Cocoa were richer, moister, more chocolatety." Why don't you try it and see?
