This is the recipe my mom used to make my birthday cake when I was a little girl, and the recipe for my son's cake when he requests chocolate. It is very similar to the other Chocolate Coca-Cola Cakes, but the main difference is the little bit of cinnamon that is in it. It is our favorite chocolate birthday cake. For a prettier cake, you can use double-boiler seven minute frosting....it's not chocolate, but it does make a very pretty cake! It is a nice white frosting...almost like a meringue type frosting. Cook time does not include the 7 minutes for the white icing!
