Cook pie crust according to package or recipe instructions. Let cool completely before adding the cream pie filling.
In a small bowl, combine heavy whipping cream and powdered sugar. Beat with a hand mixer, or stand mixer, until stiff peaks form. This will take several minutes.
In a separate larger bowl, combine the softened cream cheese, brown sugar, and pure maple syrup. Beat together until combined and creamy. Fold the whipped cream into the cream cheese mixture and stir together until combined. Stir in 1 cup of the chopped pecans.
Spread mixture into the baked and cooled pie crust. Sprinkle the remaining pecans on top of the pie. Cover and let refrigerate for 8 hours or overnight before serving.
