Preheat the oven to 350 degree F. Line two baking sheets with parchment paper and set aside.
In a medium-sized bowl, whisk together the flour, baking soda, salt, and spices. Set aside for a moment.
In the bowl of a stand mixer, cream the butter and sugars for 2 minutes, or until light and fluffy. Add the egg, vanilla extract, and pumpkin puree. Beat for an additional minute.
Little by little, add the dry ingredients. Mix until just combined, scraping down the sides of the bowl as needed.
Using a 2 tablespoon-sized cookie scoop, scoop the dough onto the prepared baking sheets, leaving 2 inches between dough.
Bake 9-11 minutes, or until the tops of the cookies are just set.
