Better than You Know What Cake

1 pkg. devil's food, chocolate, or German chocolate cake mix
1 can sweetened condensed milk
caramel ice cream topping
1 (8 oz.) container frozen whipped topping, thawed
4-5 Health or Skor bars, chopped up

Bake cake according to package directions for a 9x13 inch pan; cool for about 5 minutes. Using the handle of a wooden spoon, poke holes into the cake. Let the cake cool for a little while. Slowly pour sweetened condensed milk over the cake, letting it sink into the holes; then drizzle some of the caramel over the top of the cake. Let cake cool completely (I usually cover it and put it in the fridge for a while). Top cake with whipped topping.Decorate the top of the cake with candy bar chunks and swirls of caramel topping. Refrigerate a little longer, then serve!
