Preheat oven to 350F and grease a 9x13 baking dish.
Crush graham crackers in a food processor or crush them in a plastic Ziploc bag with a rolling pin.
In a large mixing bowl, combine the graham crackers and melted butter until well combined.
Spread and press down the crust mixture into a 9x13 baking dish with your hands or the back of a spatula. Place in the oven and bake for 7 minutes.
Allow the crust to fully cool once finished baking.
In a large mixing bowl, beat the softened cream cheese, powdered sugar, and vanilla extract until smooth. Fold in half of the whipped topping until fully incorporated.
Spread the cream cheese mixture evenly across the top of the cooled graham cracker crust.
Pour the peach pie filling across the top of the cream cheese layer and spread evenly.
Next, spread the remaining whipped topping over the top of the pie filling layer.
Garnish the whipped topping layer with chopped pecans. (optional)
Chill in the refrigerator for at least 1-2 hours, or overnight, before serving. Slice and serve, enjoy.
