Better then Sex Cake

Better then Sex Cake 1 box German chocolate cake mix 1 14oz can sweetened condensed milk 1 16.5oz bottle of caramel sauce (I used Torani Original Caramel sauce rather than a caramel syrup because it's thicker) 1 16oz tub cool whip 1 bag Heath bars baking bits or about 6 Heath Bars (crumbled) Bake cake according to instructions on the box.
