1 box devils food cake mix
2 (4 oz.) boxes instant chocolate pudding
1 (9 oz.) bag Heath bars (snack size) or 6 regular size bars
1 lg. container Cool Whip
3 1/2 c. cold milk
1/2 c. coffee liqueur

Bake cake in 9 x 13 inch pan according to package directions. Cool cake completely. Mix both boxes of pudding with milk. When thick, add liqueur and blend until smooth. Crush Heath bars into small pieces.

TO ASSEMBLE: Cut cake into 2 inch squares. Use enough cake squares to cover the bottom of a triffle bowl (or deep glass bowl). Spoon a layer of pudding over cake to cover completely. Spread a layer of Cool Whip over pudding to sides of bowl and sprinkle with Heath bar pieces. Continue layering in the same manner; cake, pudding, Cool Whip, and Heath bar pieces, ending with Cool Whip and Heath bar pieces.

Keep refrigerated. Serves 10 to 12.
