Bake cake as directed on box in 2 8" round cake pans. Allow to cool completely.
Place first layer on serving dish, and spread ready-made cheesecake filling evenly over layer. This will be a thick layer!
Place top layer over cheesecake filling. Frost entire cake with canned frosting.
Chop baking chocolate and place in small bowl. Heat heavy cream over low heat until almost boiling, and pour over chocolate. Mix well until smooth. Immediately pour over top of cake and allow some to run down over the sides of cake. Garnish with chocolate-dipped strawberries, if desired.
