1 large package Chocolate Sandwich Cookies
1 large package Vanilla Instant Pudding
1 large container Cool Whip
1 to 2 tsp cold coffee (or other flavorings)

Crush cookies into crumbs, (I use the food processor for this) Make pudding according to package directions. Add Cool Whip and cold coffee to pudding mixture, blend well.

Using a 9x13-inch dish, layer the bottom of the dish with cookie crumbs, then a layer of pudding mixture, more cookie crumbs, more pudding, etc.

NOTE: Depending on how creative I feel (and how much "extra time" I have on my hands) sometimes I finish up with the pudding mixture and a "dusting" of cookie crumbs, sometimes I put whole cookies on the top, occasionally I get really creative and "decorate" the top by coloring the pudding mixture.
