Blend cookies in a food processor until finely crushed. Mix in melted butter. Press crust mixture into the bottom and ¼ inch up the edges of a 9x9-inch baking dish.
Bake in the preheated oven for 7 minutes. Set aside to cool.
Whisk milk and pudding mix together for 2 minutes. Let stand until thickened, about 5 minutes.
Wipe out food processor and blend together cream cheese, 1 cup whipped topping, and confectioners' sugar. Layer cream cheese mixture over the baked crust.
