Bumpy Cake was created by Sanders Confectionery, of Detroit, Michigan, in the early 1900s and was originally known as "The Sanders Devil's Food Buttercream Cake" when it was first introduced. It is made of chocolate devil's food cake that is topped with rich buttercream bumps, and then draped in a chocolate ganache. Now more than a century old, this is a classic confection. Sanders Confectionery makes the original trademarked Bumpy Cake, but other companies have attempted to use this trademarked name many times during the cake's 100+ year history.
