You can certainly make your life easier by using high quality store-bought marshmallow fluff, caramel sauce and chocolate sauce, but since this was a cake for a Lunatic, I was a lunatic myself and made everything from scratch. You will have leftover ganache and butterscotch. I will give you an idea about what to do with your leftovers in another post. Just you wait! You really need a scale to make some of the components of this cake. Because my scale switches between ounces and grams, some of my measurements are in ounces, some are in grams and some are in volume measures because I just didn't convert to weights. The Hershey's cake has been perfected using volume measurements, so I don't feel too badly about leaving it alone.
