Soak the baking strip in water for 5 minutes. Then, wring out the strip, place it around the baking dish, and secure it with the "belt" loop. If using a homemade strip, wet it, wring it out, and attach it to the baking dish with safety pins.
Place a baking sheet in the middle of the oven and preheat the oven to 425°F.
Spray the baking dish with cooking spray. Roll the pie crust large enough to cut (2) 8 x 8-inch squares. (The dough can be pieced together.) Cut both squares and place one into the bottom of the baking dish. Set aside.
Use a whisk to make the filling by combining the corn syrup, brown sugar, butter, eggs, salt, and vanilla in a mixing bowl. Stir until well blended. Divide the filling and place into 2 bowls. In one bowl, add all the chopped pecans and stir. In the other bowl, add the whole pecans and stir.
Pour the chopped pecan filling over the bottom crust. Add the second layer of crust and spray with cooking spray.
Place the baking dish on the hot baking sheet and bake for 15 minutes. Remove from the oven and add the whole pecan filling to the cobbler. Place a sheet of aluminum foil over the pie and return to the oven.
Reduce the oven temperature to 350°F and bake for 50-55 minutes or until a thermometer in the middle of the pie registers 200°F. Remove the aluminum foil sheet for the last 20-30 minutes of baking. Cool before serving.
