Line a pan or dish with parchment paper and set aside.

Break up the pumpkin pie in a large mixing bowl, and mush it all up with your hands until the crust is broken into little pieces and incorporated throughout. It will be a wet, lumpy mixture.

Crush the graham cracker squares into crumbs using either a food processor or a ziplock bag and rolling pin.

Add the graham crumbs to the pumpkin mixture. The amount you use will depend on how wet your pumpkin mixture is (this can vary depending on the pie you use and how the filling-to-crust ratio is on the particular pie that you use). Start with about ½ cup of crumbs and add more as needed. Mix them into the pumpkin pie mixture until it has become firm enough to roll into balls and not stick too much to your hands. (I ended up using about ¾ cup crumbs which is equivalent to 8 graham cracker squares).

Using a scoop, scoop out equal portions of the mixture and roll them into balls, placing them onto the parchment lined pan or dish.
