Preheat your oven to 350F. For this recipe you will need a 9-in pie plate.
How to Make the Graham Cracker Crust
In a large bow, combine the graham cracker crumbs, brown sugar and cinnamon. Use a whisk to mix them well.
Pour the melted butter into the graham crumb mixture. Use a rubber spatula or a soup spoon to gently mix the butter into the crumbs, until all the crumbs have absorbed some of the butter.
Transfer the graham cracker crust mixture to the pie plate. You do not need to grease the pie plate because of the butter in the crust.
Use the back of a measuring cup and your fingers to press down the crust evenly on the sides and bottom of the plate. Make sure that there the crust is smooth and free of cracks, so that it can contain the filling.
How to Make the Pecan Pie Filling
Make the pecan pie filling by whisking together the brown sugar and eggs in a large bowl. Add the corn syrup , vanilla, salt and whisk until smooth. Lastly, whisk in the melted butter.
Add the roughly chopped pecans to the pie filling mixture. Fold them in with a rubber spatula until well combined.
Pour the pecan pie filling into the prepared graham cracker crust. Make sure to very carefully spread out the pecan pieces evenly in the crust, to not disturb the crust.
Transfer the pie to the preheated 350F oven. Place on the middle oven rack and bake for 1 hour. Once the center is set, remove from the oven and let cool completely before cutting into it!
