Ho Ho Cake

This tastes just like a ho ho if not better. We all gave this a ten and it will be in our family book but I'm switching the shortening to butter.

Ingredients:
***Bottom:***
1 (18.25 oz.) box Chocolate Cake Mix
***Topping One:***
3/4 cup white sugar
1/2 cup butter or margarine, softened
2/3 cup solid Crisco vegetable shortening
5 ounces can Evaporated milk
2 teaspoons Vanilla extract
***Topping Two:***
1 can Fudge frosting (16 oz.)
Directions:
Preheat oven to 350 degrees F. Lightly grease a 15-1/2" x 10-1/2" baking dish. Bake chocolate cake in baking dish, according to the directions on the box for 20-30 minutes or until cake bounces back when you touch it lightly on the top, or a toothpick inserted in the center comes out clean, except for a few crumbs. Allow to cool.
Mix sugar, butter, Crisco, evaporated milk and vanilla extract together until creamy with an electric mixer, about 10 minutes. Spread over cooled chocolate cake.
Heat opened can of fudge frosting in the microwave 30 seconds to 1 minute till pourable. Pour over white topping. Refrigerate over night.
