Peanut Butter Pie

This came from Ms. Bea, although I can't remember eating it at her house. But based off the other goodies I had there, it must be good. 3 oz. cream cheese 1 cup powdered sugar 1/3 cup peanut butter 8 oz. Cool Whip graham cracker crust

Whip cream cheese. Beat in sugar and peanut butter. Mix in Cool Whip. Pour into pie shell and chill.
