1 German chocolate cake mix
1 can sweetened condensed milk
1 jar either butterscotch, caramel or chocolate ice cream topping
1 sm. carton Cool Whip
3 or 4 Heath candy bars, crushed

Prepare cake mix according to packaged directions. Let cake cool completely. Poke holes in cooled cake and fill with sweetened condensed milk mixture (sweetened condensed milk and ice cream topping). Top cake with Cool Whip and then top Cool Whip with the crushed Heath candy bar pieces. Keep refrigerated.

NOTE: I use the butterscotch ice cream topping!
