Preheat oven to 425°F. Line 9-inch deep dish pie plate with pie crust. Bake 7 minutes. Remove crust from oven. Reduce oven temperature to 325°F.
Meanwhile, microwave chocolate chips and milk in medium microwavable bowl on HIGH 1 to 1 1/2 minutes. Stir until smooth. Pour chocolate evenly over crust.
Beat eggs in large bowl. Add remaining ingredients; mix well. Slowly pour mixture over chocolate layer. Place ring of foil around edges of crust to prevent over-browning.
Bake 55 to 60 minutes or until filling is puffed and center is still soft enough to move when shaken gently. Cool on completely wire rack.
