Patricia - This may be the recipe you are looking for. I used to make it years ago. It has a frosting made with flour, but then a second frosting layer of chocolate glaze poured over the top of the 1st frosting. It is a very dense, moist cake and delicious. I've also made it without the 2nd frosting part, just with the white flour frosting and it's good that way, too.

CHOCOLATE SPICE OATMEAL CAKE

1 stick (1/2 cup) margarine
1 1/2 cups boiling water
1 cup quick oats (not instant)
1 1/2 cups flour
2 Tbsp. unsweetened cocoa powder
1 tsp. baking soda
1 tsp. cinnamon
1/2 tsp. salt
1 cup brown sugar
1 cup granulated white sugar
2 eggs
1 tsp. vanilla
Flour Frosting (recipe follows)
Chocolate Glaze (recipe follows)

Preheat oven to 350 degrees F. Grease and flour a 13x9-inch baking pan.

Dissolve the stick of margarine in the 1 1/2 cups of boiling water. Add the oats and let stand for about 10-20 minutes.

In a separate bowl combine the flour, cocoa powder, baking soda, cinnamon, and salt; set aside.

To the cooled oat mixture, add the brown sugar, the white sugar, and eggs. Beat until well incorporated. Add the dry ingredients and beat slowly until well incorporated, then beat in the vanilla. Spread in prepared pan.

Bake in a preheated 350 degree oven for approximately 30 minutes or until center is done and tests clean with toothpick. Let cool in pan.

Spread Flour Frosting (below) over cooled cake. Top with Chocolate Glaze (below)

This is not a high fluffy cake, more a dense low cake.

FLOUR FROSTING WITH CHOCOLATE GLAZE
(1ST TOPPING)

2 1/2 Tbsp. flour
1/2 cup milk
1/2 cup sugar
1/2 cup margarine
1 Tbsp vanilla

In a small saucepan, heat flour and milk until it becomes a thick paste. Set aside to cool.

Cream the sugar and margarine together until fluffy, then add cooled flour paste and beat well until no lumps from the cold paste are visible. Add the vanilla and beat again.

CHOCOLATE GLAZE
(2ND TOPPING)

2 Tbsp. cocoa
1 cup sugar
1/4 cup milk
2 Tbsp. white Karo (light corn syrup)
1/4 cup butter

Mix all the ingredients for the glaze together in saucepan and cook until it boils - then time it boiling for 1 1/2 minutes.

Remove from heat and beat until it cools down, then pour carefully over the top of the white frosting. It will become a slightly firm shell over the white frosting layer.

Hope this is what you were looking for.
