Preheat oven to 375°F. Line two baking sheets with parchment paper and set aside.
In a small bowl, whisk together the cinnamon and the sugar. Set aside.
In a large bowl, whisk together the flour, pumpkin pie spice, baking soda, salt. Set aside.
In the bowl of a stand mixer, beat the butter until light and creamy, about 2 minutes.
Add both sugars and beat with the butter for another 2 minutes.
Add pumpkin puree and vanilla, and beat together. Batter will be combined, but wet and clumpy (this is normal)
Gradually add the dry ingredients to the wet ingredients and beat together until just combined.
Fold in the white chocolate chips.
Form 1-inch dough balls and gently roll into the prepared cinnamon sugar. Place on the prepared baking sheets. Bake for 9-10 minutes. Allow to cool for 5-10 minutes.
