The perfect combination of chocolate and Coca Cola, plus butter and sugar!! It doesn't get much better than this Coca Cola Chocolate Cake!!
Preheat your oven to 350 degrees.
Grease and flour an 11x17 inch pan or roasting pan. I did use a Pyrex 4.8 Quart pan next time I will leave some of the batter out as it still overflowed a bit.
Combine the flour, cocoa powder, cinnamon, salt, baking soda, and sugar in a mixing bowl, and set aside.
In a pan on the stove at low heat, heat the butter with the cups of Coca-Cola until the butter has melted.
Next add eggs, vanilla, and buttermilk to the butter and butter mixture and mix well.
Add the Coca-Cola liquid mixture into the dry ingredients and beat until mixed well.
Pour batter into the baking pan and bake for 30 minutes. (You could make 2 tube pans baked for 60 minutes or 24 cupcakes baked for 15 minutes.)
In a saucepan, heat together the butter and Coca-Cola. Be sure not to boil.
Add in the remaining ingredients and mix well.
Pour icing over the cake. You must ice this cake warm!
