Pre-heat the oven to 350 degrees. 

Lightly grease a glass pie plate with butter or cooking spray. This helps the crust come out more easily when serving.

In a food processor, add the graham cracker sheets. Pulse until they’re crumbly–you may have to create crumbs in batches if using a smaller mixer.

Pour the graham cracker crumbs into a medium sized bowl. Add the brown sugar, ground cinnamon, salt and melted butter. Mix with a spatula or wooden spoon until combined.

Scoop the crumbs into the bottom of the greased pie plate. Gently press the crumbs with your fingertips, forming the bottom of the pie crust and the sides along the pan.

You can also use the bottom of a measuring cup to lightly pack the crumbs into a pie crust shape. Whichever method, be sure that the crust is even throughout.

Put the pie plate on a sheet pan, and bake the graham cracker crust in the oven for 10-12 minutes. Remove from the oven, and let the crust completely cool.

Fill the crust with your favorite pie filling.
