Preheat oven to 350 degrees.

Spray a 9x13 baking dish with baking spray. Set aside.

To make the crust:

Stir together the flour and brown sugar in a medium bowl.

Add the cubed butter.

Mix and squeeze the butter with the flour and sugar mixture until coarse crumbs form.

Press the coarse crumbs evenly into the bottom of the prepared baking dish.

Bake the crust for 10 minutes. Remove and cool.

To make the filling:

While the crust is baking whisk the eggs, granulated sugar, corn syrup, salt, and vanilla extract until thoroughly combined.

Whisk the cooled melted butter into the egg and sugar mixture, and stir in the pecans.

Pour the filling mixture over the crust mixture and tilt the pan back and forth to evenly distribute the filling liquid evenly over the entire crust.

Manually distribute the pecans evenly over the entire crust and then sprinkle the chocolate chips over top.

Cover the dish with tin foil and bake for 15 minutes.

Remove the dish from the oven, uncover, and return the dish to the oven to continue baking for an additional 30 minutes.

Remove from the oven, cool completely and cut the into bars for serving.
