1 chocolate cake, either package mix or scratch

When you take the cake out of the oven, poke holes in it and pour 1/2 cup Kahlua over it; let set several hours. Crumble cake and add the following in order. (Make layers, you can make 8 layers and 2 separate serving dishes; it makes a huge amount).

2 lg. pkgs. chocolate pudding (you can use sugar free made with skim milk to cut down the calories)
2 lg. Cool Whip
6 lg. Heath bars, crumbled

This looks pretty in a glass container.
