I received a booklet from Kraft Foods today which is called "food & family" and this is one of the recipes in it that I am posting here to try at a later date. One of their winning desserts! NOTE: Cooking time = refrigeration time.
Cut cake into 2 layers with serrated knife. Beat 1 cup milk and pudding mix with whisk 2 minutes. Stir in whipped topping. Let stand 5 minutes.
Stack cake layers on serving plate, spreading pudding mixture between layers.
Microwave chocolate and butter on high for 1 minute. Stir until chocolate is melted. Add sugar and 2 tablespoons milk; mix well. Spread over cake. Refrigerate 1 hour. Refrigerate leftovers -- if there are any!
