Better Than Anything Cake (Well...almost anything!)

I made this for the girl's basketball team for Nicki's birthday and it was a HUGE hit!  I made two of them and they were gone in literally seconds!

1 pkg Betty Crocker SuperMoist German Chocolate Cake Mix
Water, oil, and eggs as called for on mix directions
1 can sweetened condensed milk
1 16oz jar caramel topping
1 8oz cool whip, thawed
1 bag toffee chips or skor candy bars chopped up

Heat oven to 350.  Make and bake cake as directed on box, for 9x13 pan.  Cool for 15 minutes.  Poke top of cake all over with handle of wooden spoon or straw.  Drizzle with milk evenly; let stand until milk is absorbed.  Drizzle with caramel (I only use half the jar because it's too sweet).  Run knife along sides of pan to loosen cake.  Cover and refrigerate 2 hours.  Spread cool whip over top then sprinkle with toffee.  Store in fridge till ready to eat.  (I also drizzle a little more caramel on some hot fudge over the top!)
