1 baked pie shell
1 c. cold milk
1 pkg. (4 servings) instant chocolate pudding
3 1/2 c. (8 oz.) Cool Whip, thawed

Rocks - Granola chunks, Heartland cereal, mini chocolate chips, peanut butter chips, chopped peanuts or a combination of the above.

Pour milk into medium bowl. Add pudding. Beat with wire whisk until blended - about 1-2 minutes. Let stand 5 minutes. Fold in Cool Whip. Stir in 1 cup of cookies and the "rocks". Spoon into crust. Sprinkle remaining cookies over top. Freeze until firm, about 4 hours.
