Cook the pie crust following the instructions on the package.
While the crust cools, you can make the filling.
Beat the cream with the powdered sugar, using an electric mixer, until you get stiff peaks.
In another bowl, beat the brown sugar, cream cheese, maple syrup, and salt, until creamy and smooth.
Now fold the whipped cream into the other mixture.
Stir in a cup of the nuts.
Spread the filling into the crust once it’s completely cool.
Decorate with the rest of the pecans, then chill for at least 2 hours before serving.
