Chocolate Cake

I found a collection of old recipes at DI. I sifted thru all 800 of them and found most of them to be keepers. I tried this one for Maggies birthday. The frosting was the best part of it.

1 1/2 cups butter
2 cups sugar
5 eggs
3 cups flour
1/2 cup cocoa
1/2 tsp baking soda
1/2 tsp baking powder
1 1/4 cups milk
1 tsp vanilla extract
Bake 350 for 40 minutes

Frosting:
2 cups whipping cream, whipped
1 jar chocolate fudge sauce (the kind you put on ice cream)
1 tsp vanilla extract
