Step 1: Preheat your oven to 350°F (175°C) and prepare a 9x13-inch baking dish by greasing it or lining it with parchment paper.
Step 2: In a large mixing bowl, combine the all-purpose flour and granulated sugar. Pour in the melted butter and mix until crumbly.
Step 3: Spread the mixture evenly in the bottom of the prepared baking dish and press down firmly to form the crust. Bake for about 15 minutes until light golden brown.
Step 4: In another bowl, whisk together the corn syrup, packed brown sugar, eggs, vanilla extract, and salt until smooth. Stir in the chopped pecans.
Step 5: Pour the pecan filling over the baked crust and spread evenly. Bake for an additional 25-30 minutes until the filling is set but slightly jiggly in the center.
Step 6: Allow the bars to cool completely in the pan on a wire rack before cutting into squares or rectangles.
Notes
Letting the bars cool completely will help them hold their shape when cut. For extra crunch, toast the pecans before adding them to the filling.
