Preheat the oven to 350°F and line two cookie sheets with parchment paper.
In a medium bowl, whisk together the flour, pumpkin pie spice, baking soda and salt.
In a large bowl, whisk together the sugars, pumpkin, oil, egg and vanilla extract until smooth.
Transfer the dry ingredients on top of the wet ingredients and mix together with a rubber spatula. Fold in the chocolate chips.
Using a medium spring-loaded cookie scoop, scoop about 1.5 tablespoons of the cookie dough and place it on one of the prepared baking sheets, spaced at least two inches apart.
Bake for 11-13 minutes, or until the edges are lightly golden. The centers should be slightly soft.
Remove from the oven and let the cookies cool completely on the baking sheet before enjoying.
