Barbara:

Here's an excellent recipe. It is virtually fat free:

Chocolate Cake

3 cups flour (all-purpose)
6 Tblsp cocoa
1 tsp salt
2 Tblsp vinegar
2 cups warm water
2 cups sugar
2 tsp baking soda
2 tsp vanilla
3/4 cup applesauce

Mix all ingredients together. Pour into 2 8" layer pans or 1 9x13 pan. Bake at 350 degrees for 25-30 minutes (longer for rectangular pan) or until center springs back when lightly pressed.

This cake can be served frosted or plain--it's really moist. If you plan on leaving it in the pan, you don't need to grease/flour the pan. If you want to make sure it will flip out, I would grease/flour the pan.
