Preheat oven to 325˚.
In a large mixing bowl, combine brown sugar, granulated sugar, eggs, butter, milk, flour, vanilla and salt. Mix well.
Stir in chopped pecans and chocolate chips.
Pour into prepared pie crust and place on a baking sheet covered with parchment or silicone mat to catch any drips.
Decorate with whole pecans if desired.
Bake for 55 minutes or until the top is set and the crust is browned. The center should still jiggle a bit.
Cool completely before serving. The pie will need to set up to have nice slices
