1 c. cold milk
1 (4-serving size) pkg. chocolate instant pudding
1 (8 oz.) Cool Whip, thawed
20 Oreo cookies, crushed
1 1/2 c. "rocks"
1 graham cracker pie crust

For "rocks" use granola chunks, chocolate chips, peanut butter chips, chopped peanuts, or combination.

Pour milk into medium bowl. Add pudding mix. Beat with wire whisk until well blended, about 1-2 minutes. Let stand 5 minutes. Fold in whipped topping.

Stir in 1 cup crushed cookies and the "rocks". Spoon into pie crust. Sprinkle with remaining cookies. Freeze until firm, about 4 hours. Garnish with gumdrop flowers if desired.
