Grease a 9x13 inch baking dish and preheat your oven to 350°F (175°C).
In a medium bowl, combine the graham cracker crumbs, melted butter, and 1/3 cup of granulated sugar. Press the mixture evenly into the bottom of the prepared baking dish.
Bake the crust for 8 minutes. Remove from the oven and let it cool completely.
In a large mixing bowl, beat the softened cream cheese until smooth. Gradually beat in the remaining 1/3 cup of granulated sugar until well combined.
Fold in one thawed container of Cool Whip into the cream cheese mixture until just combined. Spread this mixture evenly over the cooled graham cracker crust.
In a separate large bowl, whisk together the instant pumpkin pie pudding mix and the whole milk according to the pudding package directions for pie filling.
Gently spread the pumpkin pudding mixture over the cream cheese layer.
Top the pudding layer with the remaining two thawed containers of Cool Whip.
Sprinkle the pecan pieces evenly over the top of the Cool Whip.
Cover the dish and refrigerate for at least 8 hours, or preferably overnight, to allow the dessert to set completely before slicing and serving.
