Yummy Peanut Butter and Chocolate Dessert

I made and brought this to John's birthday party at Chuck E Cheese. It tasted like a giant peanut butter cup, so yummy!

Peanut Butter Chocolate Dessert(sorry, no picture)
20 cream filled chocolate sandwich cookies, divided (oreos)
2 Tablespoons butter, melted
1 pkg. (8oz) cream cheese, softened
1/2 cup peanut butter
1 1/2 cup powder sugar, divided
1 carton(16oz) frozen whipped topping, thawed, divided
25 miniature peanut butter cups, chopped
1 cup cold milk
1 pkg. (3.9oz)instant chocolate pudding mix
Crush 16 cookies, toss with butter. Press onto bottom of ungreased pie dish(I used springform pan). In a mixing bowl, beat cream cheese, peanut butter and 1 cup powder sugar until smooth. Fold in half of the whipped topping. Spread over crust. Sprinkle with peanut butter cups. (save a few for the top)
In a separate mixing bowl, beat the milk, pudding mix, and remaining powder sugar on low speed for 2 minutes. Fold in whipped topping. Spread over peanut butter cups. Crush remaining cookies, sprinkle over the top and sprinkle with last few PB cups. Cover and chill for at least 3 hours prior to serving.
