This recipe came from the 1950s and the cake is very moist, rich, and delicious! It takes a little time, but it is worth it and much better than any mix, even better than any bakery cake I've ever tasted. The texture is just perfect. I hope you all enjoy it.

Exactly what you think of when you read German chocolate cake. Preparing this super easy cake in a sheet pan means it's a good dessert option when serving a crowd.
