Instructions: Preheat the Oven: Preheat your oven to 350°F (175°C).If using a homemade or store-bought pie crust, place it in a 9-inch pie dish. Crimp or flute the edges as desired.
Make the Cheesecake Filling: Mix in the vanilla extract, sour cream, and all-purpose flour until the batter is smooth and well combined.
Pour the Filling: Pour the cheesecake filling into the prepared pie crust, spreading it evenly.
Bake: Place the pie in the preheated oven and bake for 35 to 40 minutes, or until the filling is set and the pecans are golden brown.
Cool and Chill: Once cooled to room temperature, transfer the pie to the refrigerator and chill for at least 4 hours, or preferably overnight, to set completely.
Serve: Before serving, slice the pecan cheesecake pie and serve chilled, savoring the creamy texture and nutty flavor combination.
