Make crust: Grease a shallow pie dish with cooking spray. In a large bowl using a hand mixer, beat butter and sugar until smooth. Add flour, vanilla and salt and beat until combined. Stir in mini chocolate chips.
Press about two-thirds of the mixture into greased pie dish. Refrigerate while you make the filling and topping.
Make filling: In a large bowl whisk together milk and pudding mix until smooth and thickened, about 5 minutes. Fold in Cool Whip and melted chocolate until evenly combined. Pour filling into crust.
Make topping: Roll extra cookie dough into small balls. Place in a pile on top of filling.
Freeze pie until the filling is solid, about 4 hours.
Slice and serve cold.
