Preheat oven to 375˚F.
In a large bowl, cream together the sugars, butter, and pumpkin. Add egg and vanilla and mix until fully incorporated.
In a medium bowl, sift together the flour, baking soda, salt and cinnamon.
Slowly add the dry ingredients to the wet ingredients and stir until the flour mixture is moist. Mix in the chocolate chips.
Using a medium cookie scoop, drop rounded tablespoonfuls of the batter onto a non-stick cookie sheet. Bake for 10-12 minutes, or until the bottom of the cookies are slightly brown.
Allow to cool for around 5 minutes on the cookie sheet before transferring to wire racks to cool completely.
