1 chocolate cake mix
2 boxes chocolate mousse mix
1 lg. Cool Whip
3 lg. Heath bars, crushed
3/4 c. Kahlua

Make cake mix according to package directions. When cool, pole holes in cake with fork and pour Kahlua over it. Break up 1/2 the cake (save the other half for another time; it can be frozen). In a pretty, clear glass bowl put 1/2 of the crushed up cake, a layer of mousse, Cool Whip, then Heath bars. Then layer each again, ending with the Heath bars. Refrigerate until serving time.
