Preheat oven to 350°F (177°C). Line a 9x13 baking pan with parchment paper, leaving some overhang for easy lifting.
Prepare the crust: In a mixing bowl, combine flour, sugar, melted butter, and salt until a soft dough forms.
Press the crust mixture firmly and evenly into the bottom of the prepared pan.
Bake the crust for 15 minutes, or until the edges begin turning lightly golden.
While the crust bakes, whisk together eggs, granulated sugar, corn syrup, melted butter, vanilla extract, pecans, and salt until well combined.
Pour the filling evenly over the warm crust immediately after it comes out of the oven.
Return the pan to the oven and bake for 30–35 minutes, or until the center is set and no longer jiggles.
Let the bars cool completely in the pan before lifting them out and slicing into squares.
