Hope this is what you're looking for. It's a recipe I cut out of the Austin American Statesman years ago. I made it once, and as far as I can remember, it was good -- and rich!

MISSISSIPPI MUD CAKE

2 cups sugar
1 cup solid all-vegetable shortening
1/3 cup cocoa
1 cup chopped nuts
4 eggs
1-1/2 cups all-purpose flour
3 teaspoons (1 tablespoon) vanilla
1/4 teaspoon salt
1 (7 oz.) jar marshmallow creme
Icing

Preheat oven to 350 degrees. Grease and flour a 13 x 9 x 2-inch pan. Mix cake by hand; combine ingredients except marshmallow creme and beat until smooth. Pour into prepared pan. Bake 35 minutes at 350. Spread marshmallow creme on top and return to oven 5 minutes or until creme is bubbly. Remove from oven and cool, then frost.

ICING:

2 stick butter or margarine, melted
1 teaspoon vanilla
1 (1-pound) box powdered sugar
1/2 cup evaporated milk
1/2 cup unsweetened cocoa
1 cup chopped nuts

Combine margarine, vanilla, sugar, milk and cocoa and let sit about 30 minutes. Beat until smooth. Add nuts.
