In a mixing bowl, combine the pumpkin puree and softened cream cheese until smooth.
Add in the powdered sugar, vanilla extract, and pumpkin pie spice. Mix until fully combined.
Fold in the crushed graham crackers into the mixture.
Chill the mixture in the refrigerator for about 30 minutes.
Once chilled, scoop out tablespoon-sized portions and roll them into balls.
Melt the white chocolate chips in the microwave or a double boiler until smooth.
Dip each ball into the melted white chocolate, ensuring they're fully coated, then place on a parchment-lined tray.
Refrigerate the coated balls for an additional 15-20 minutes until the chocolate sets.
