Step 1: Place candy bars in freezer. Bake cake according to directions on the box in a 9x13 inch cake pan.
Step 2: Immediately after removing cake from oven, poke holes all over the top with a fork. (The more holes, the more caramel gets into the cake).
Step 3: Mix sweetened condensed milk and caramel together, and pour over hot cake, spreading it over the entire cake.
Step 4: Chill cake in the refrigerator for at least 2 hours.
Step 5: When cake is chilled, take it out of the refrigerator.
Step 6: Pull candy bars out of freezer and smash with a hammer while they are still in their packages. Sprinkle 2 candy bars evenly all over the top of the cake.
Step 7: Spread Cool Whip over the top, then sprinkle the remaining 2 candy bars on top of the Cool Whip.
Step 8: Chill for at least 1 hour before serving.
Step 9: Store leftover cake in the refrigerator.
