Prepare brownie mix, and bake according to package directions in a 13x9x2 pan. Prick top of warm brownies at 1- inch intervals using a fork; drizzle with kahlua. Let cool.
Prepare pudding mix according to package directions, omitting chilling.
Repeat layers twice with remaining ingredients, ending with crushed candy bars. Chill 8 hours.
* 4 tablespoons of strong brewed coffee and 1 teaspoon sugar may be substituted for kahlua. Also, I make it without kahlua and it's very good. I have also put orange flavoring in my brownie mix for something different. * I use Heath candy bars.
