Preheat oven to 350°F. Grease or line a 9×13 baking dish with parchment paper.

In a bowl, cream butter and brown sugar until light and fluffy.

Mix in flour and salt until the dough is crumbly. Press evenly into the baking dish.

Bake the crust for 18–20 minutes until lightly golden.

While the crust bakes, whisk together eggs, brown sugar, corn syrup, granulated sugar, vanilla, and salt.

Stir in the chopped pecans.

Pour the mixture over the hot crust.

Return to the oven and bake for 30–35 minutes until just set in the center.

Let cool completely before slicing into bars.

Optional: Chill for clean, sharp edges.
