Lightly grease a 9x13-inch pan and line it with parchment paper. (Makes it easy to lift out and cut the bars.)
Preheat oven to 350 degrees Fahrenheit.
FOR THE CRUST: Place all ingredients in a food processor or blender and pulse until dough starts to ball up. Press the dough evenly into the bottom of the prepared baking pan. Bake for 20 minutes; edges should be just starting to brown. Remove from oven and pour on the pecan pie filling while still HOT.
FOR THE PECAN PIE FILLING: Whisk the flour and brown sugar together well in a large bowl (no lumps). Add the eggs, vanilla, salt, and corn syrup. Whisk until incorporated. Let mixture stand while crust bakes.
Whisk filling well just before the crust comes out of the oven. Add the chopped pecans, mix, and pour over HOT crust.
Return pan to oven and bake an additional 25 to 30 minutes, until filling is set. Shake the pan; the center can wobble like set jelly, but should not be runny.
Cool to room temperature, then CHILL in the fridge several hours, or overnight.
Lift pecan pie bars from the pan after they are fully cooled. Remove parchment paper, and place on a cutting board. Use a sharp serrated knife to saw through the nut layer before pressing through the bottom layers. Store leftovers in the refrigerator.
