Sift together flour, 1 cup sugar, cocoa, soda and salt in an ungreased 12" x 8" baking pan. Make 3 wells in the mixture; pour oil in one, vinegar in one and vanilla in one. Pour in coffee and stir all with a fork until well mixed. Spread into an even layer.

 

Combine 1/3 cup sugar and cinnamon; sprinkle half over batter. Bake in 350 degree F oven for 35 to 40 minutes. Sprinkle remaining cinnamon sugar over hot cake.

 

Cool 15 to 20 minutes before cutting.

 

This scrumptious delight costs approximately $.33 per serving. The cake is made in one pan, so preparation time is at a minimum. It's also fun to make!
