Preheat your oven to 350°F (175°C). Lightly coat a 9-inch pie dish with vegetable oil cooking spray.
02 -
In a medium bowl, mix together the chopped pecans, softened butter, brown sugar, and salt until well combined. Press this mixture firmly and evenly into the bottom and up the sides of your prepared pie dish to form the crust.
03 -
Bake the pecan crust for 12-15 minutes, until lightly golden brown and fragrant. Remove from oven and set aside to cool completely.
04 -
In a medium saucepan, whisk together the granulated sugar, flour, and salt. Gradually whisk in the milk until smooth, making sure there are no lumps.
05 -
Place the saucepan over medium heat and cook, stirring constantly with a wooden spoon or heat-resistant spatula, until the mixture thickens and comes to a gentle boil, about 6-8 minutes. Reduce heat to low and continue cooking for another minute, still stirring constantly.
06 -
Remove saucepan from heat. Slowly pour about 1 cup of the hot mixture into the beaten egg yolks, whisking continuously to prevent the eggs from cooking. Then pour the tempered egg mixture back into the saucepan, whisking vigorously to combine.
07 -
Return the saucepan to low heat and cook for another minute, stirring constantly. Remove from heat and immediately stir in the unsalted butter and vanilla extract until fully melted and incorporated.
08 -
Pour the butterscotch filling into the cooled pecan crust. Cover the pie with plastic wrap, pressing it directly onto the surface of the filling to prevent a skin from forming. Refrigerate for at least 3 hours, or preferably overnight, until the filling is completely set.
09 -
Remove the plastic wrap and serve chilled. For an extra touch, garnish with whipped cream and a sprinkle of chopped pecans if desired.
