1 (19.8 oz.) family size fudge brownie mix
1/4 to 1/2 c. Kahlua or coffee liqueur
3 (3.5 oz.) boxes Jello chocolate mousse
8 (1.2 to 1.4 oz.) size Skor or Heath bars
1 (12 oz.) carton whipped topping

Bake brownies according to package directions. Cool. Punch holes in brownies with fork and pour Kahlua over brownies; set aside. Whip up Jello chocolate mousse according to package directions. Break Skor or Heath bars into small pieces in food processor or by tapping with a hammer (right in the wrapper). Break up half of the brownies and place in the bottom of a glass trifle dish. Cover with half of the mousse, layer with half the candy and then add half of the whipped topping. Repeat layers with the remaining ingredients.
