Step 1

Bake cake according to package directions for a 9x13 inch pan.  Cool for about 15 minutes. Using the handle of a wooden spoon, poke holes into the cake.

Step 2

In a small bowl, combine sweetened condensed milk and caramel topping.  Optional - reserve some caramel topping to drizzle on top of the cake. Slowly pour caramel mixture over the cake, letting it sink into the holes.

Step 3

Let cake cool completely (I usually cover it and put it in the fridge until I'm ready to serve it). Top cooled cake with whipped topping.

Step 4

Decorate the top of the cake with chopped candy bars. Optional - drizzle caramel topping and chocolate syrup over the cake with the candy bars. Keep refrigerated until ready to serve.
