Chocolate Trail Drive Cake - cooking recipe

Ingredients

1 1/2 cups sugar, and extra sugar for the top
1/2 cup cocoa, I like to use 1/4 cup regular cocoa and 1/4 cup dark cocoa
2 teaspoons baking soda
2 1/2 cups flour
1 -2 teaspoon cinnamon, your choice
1 tablespoon vanilla
2 tablespoons vinegar
1/2 cup oil
2 cups cold strong coffee, stronger the better

Preparation

In 13x9 metal pan mix sugar, baking soda, cinnamon and cocoa to break up cocoa lumps then add flour.
Then add vanilla, coffee, oil, and vinegar and mix with fork but do not beat.
Sprinkle sugar, about 1/2 cup or enough to create a layer just barely white on the top. Bake at 350 about 30 minutes. Do not cover while warm or sugar topping will melt. I have tried glass pans but it does not do as well.
