Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a mixing bowl, cream together softened butter and brown sugar until light and fluffy.
Add flour and salt, mixing until a soft dough forms.
Scoop tablespoon-sized portions of dough and roll into balls.
Place dough balls on the prepared baking sheet and gently press each to flatten while creating a shallow indentation in the center.
Bake cookies for 8 minutes.
Meanwhile, prepare pecan pie filling by combining chopped pecans, light corn syrup, granulated sugar, eggs, and vanilla extract in a bowl.
Remove partially baked cookies from the oven and spoon about a teaspoon of pecan filling into each cookie’s indentation.
Return cookies to the oven and bake for an additional 7 minutes, until the filling is set and edges are golden.
Cool cookies on the baking sheet for 10 minutes, then transfer to a wire rack to cool completely.
