Add graham crackers and pecans to your food processor and pulse until coarsely ground. Add sugar and butter and continue to process until finely ground and completely combined.
Press mixture into the bottom and up the sides of a 9-inch pan. (If using for a cheesecake, only press firmly to the bottom and NOT up the sides of springform pan). Press the mixture firmly until compact, using your fingers as an edge guide.
For a NO BAKE Dessert Pie, chill Crust in the freezer for one hour or chill in the refrigerator for 2+ hours. For a BAKED PIE, bake Crust at 350 F degrees for 10 minutes. If crust puffs up, press down with the back of a measuring cup.
Let the Crust cool completely before filling and returning to the oven with your pie filling (you can place in the refrigerator to speed cooling process along).
You can completely prepare the Crust 24 hours in advance of filling and cover with plastic wrap to make your pie making even easier!
