Preheat your oven to 350°F (175°C). Press the pie crust into a 9-inch pie pan and chill while preparing the filling.

Melt the butter and butterscotch chips in a microwave-safe bowl for about 1.5 minutes, stirring until smooth.

In a large mixing bowl, whisk together eggs, corn syrup, and vanilla, then mix in the melted butterscotch until smooth.

Fold in the chopped pecans, ensuring they are well coated with the filling.

Pour the filling into the chilled pie crust and bake for 60 to 70 minutes until mostly set with a slight jiggle.

Allow the pie to cool at room temperature for about 2 hours before slicing and serving with whipped cream or ice cream.
