Bake or buy brownies. Cool. Poke holes in brownies and pour Kahlua or coffee into holes. Prepare mousse according to package directions. Crush candy bars by hitting with hammer while still in wrapper. Crumble 1/2 brownies into Trifle, or large, round glass bowl. Layer:
1/2 mousse
1/2 candy, removed from wrappers
1/2 Cool Whip
Repeat. Refrigerate until ready to serve.
OPTIONS: Substitute Amaretto or cherry herring for Kahlua. Layer dark bing cherries, drained or canned pie cherries with other ingredients on top of brownies.
