1 dark chocolate cake mix
1 (6 pack) Heath bars or 2 pkgs. Heath bits
2 lg. tubs of Cool Whip
3/4 c. Kahlua
4 (3 oz.) chocolate instant pudding

Prepare cake mix as directed and bake in a 9 x 13 inch pan. Poke holes in the cooled cake and pour Kahlua over it. Prepare pudding as directed. Crush Heath bars with a rolling pin. In a trifle bowl, put 1/3 of the cake (crumbled), then 1/3 pudding, then 1/3 Cool Whip, and 1/3 candy. Repeat layers 2 more times, ending with Cool Whip and candy. Make a day ahead and store in the refrigerator. May be made in smaller proportions by halving all ingredients.
