This recipe makes a lot of frosting so that you will have plenty to put between each of the 3 layers of round cake. If you are a lover of this frosting like I am then even if you place them on a large single layer cake you will have enough. In my humble opinion it is the frosting which makes German Chocolate Cake so special. Substitutions don't work for me when it comes to this frosting. Especially NOT those canned versions.
