Grandma's Oatmeal Cake

Pour boiling water over oats; add margarine.

Cover and let stand 10 minutes.

Stir in eggs, vanilla and sugars.

Add dry mix. Bake at 350° in a greased and floured 9 x 13-inch pan for 35 minutes.

When it comes out of the oven, sprinkle with a mixture of cinnamon and sugar (1/2 cup white sugar and 1 teaspoon cinnamon). This is a very moist cake so a toothpick test won't work.
