Kiped from the 'net:

INGREDIENTS:

* 1/2 cup shortening
* 1 1/2 cups sugar
* 2 eggs
* 2 tablespoons cocoa
* 1 1/2 oz red food coloring
* 1 teaspoon salt
* 2 1/2 cups flour
* 1 teaspoon vanilla
* 1 cup buttermilk
* 1 teaspoon soda
* 1 tablespoons vinegar

Cream shortening; beat in sugar gradually. Add eggs, one at a time; beat well after each addition. Make paste of cocoa and food coloring; add to creamed mixture. Add salt, flour and vanilla alternately with buttermilk, beating well after each addition. Sprinkle soda over vinegar; pour over cake batter. Stir until thoroughly mixed. Bake in 3 8-inch greased pans or 2 9-inch greased pans in a preheated 350 degree oven for 30 minutes. (I used one jelly roll pan for about 20 minutes -- easier to give kids small pieces.)

Frosting:

Cream:

* 4 ounces butter, softened
* 1/2 cup shortening
* 1 cup granulated sugar

Beat till very fluffy

Then add:

* 3 tablespoons flour - 1 tablespoon at a time
* 2/3 cup milk, room temperature
* 1 teaspoon vanilla

Beat hard and long at high speed until very smooth and creamy and the gritty texture is gone.

This is really sweet (though my sugar tolerance may be low), but it's pretty good.
