I got the recipe from allrecipes.com, one of my very favorite online resources. I've changed it a little bit, but not much.
Chocolate Oatmeal Cake
2 cups quick oatmeal
2 sticks margarine
3 cups boiling water
1 cup cocoa
3 cups granulated sugar
2 cups all-purpose flour
2 teaspoons baking soda
Heat oven to 375 degrees F. Grease and flour a 9 by 13 pan.
Pour boiling water over the oatmeal and margarine, let set for 20 minutes, stirring frequently.
Add eggs to the oatmeal mixture, blending well. Mix in remaining ingredients and pour into prepared pan.
Bake for about 30-40 minutes or until it tests done.
