Combine the corn syrup, brown sugar, melted butter, beaten eggs, pure vanilla extract, and salt in a large mixing bowl and whisk until fully combined. Stir in the chopped pecans.
Spray the edges of the foil or parchment paper with nonstick cooking spray, then pour the mixture on top of the warm crust and spread it around into one even layer.
Return to the oven and bake at 350°F (177°C) for 25-30 minutes or until the topping is set and lightly browned.
Remove from the oven and transfer to a wire rack to cool completely.
Once cooled, lift the bars out of the pan using the overhang from the foil or parchment paper, slice into bars, serve, and enjoy!
