Chocolate Sheet Cake

1 cup Butter
4 TB Cocoa
1 cup Water
2 cups Flour
2 cups Sugar
1/2 cup Buttermilk*
1 tea Baking Soda
1 tea Cinnamon
1 tea Vanilla
2 Beaten Eggs
Dash of Salt

Boil butter, cocoa, and water pour into mixing bowl. Mix all dry ingredients in a separate bowl. Add buttermilk, vanilla, and dry ingredients to the melted mixture begin to beat. Add eggs. Pour into a prepared half sheet cake pan. Bake at 400 for 15-20 minutes.  Frost with Chocolate frosting. I like to frost when still a little warm.
*If you do not have buttermilk you can add a little lemon juice to milk allow to sit for a few minutes.
