Preheat your oven to 350°F (175°C) and line an 8-inch square baking pan with parchment paper.

In a medium bowl, combine all-purpose flour, light brown sugar, and salt. Incorporate cold, cubed butter until it resembles coarse crumbs. Press mixture evenly into the prepared pan and bake for 15 minutes until lightly golden.

While the crust is baking, whisk together corn syrup, granulated sugar, eggs, vanilla extract, and melted butter until smooth. Fold in the chopped pecans.

Pour the pecan filling evenly over the hot crust. Bake for an additional 20 to 25 minutes until the filling sets with a slight jiggle in the center.

Let the bars cool completely in the pan on a wire rack. Once cool, lift the bars out using the parchment overhang and slice into squares.
