Preheat oven to 375°F and line two cookie sheets with parchment paper or grease lightly with nonstick cooking spray.
In a stand mixer fitted with the paddle attachment, cream together the softened butter, brown sugar and granulated sugar until light and fluffy. This takes about 2-3 minutes.
Add the pumpkin puree and vanilla extract. Mix until smooth.
Add the dry ingredients: baking soda, baking powder, cinnamon, salt, and all purpose flour. Mix on low speed just until combined and flour is just incorporated.
Fold in chocolate chips.
Using a large cookie scoop (3.25 oz) or scant ½ cupful, make 12 cookie dough balls placing 6 on each prepared cookie sheet.
Roll dough into balls and flatten just slightly with the palm of your hand, but not too much, to resemble a thick hockey puck.
Bake one pan at a time, in center of oven for 16-18 minutes until the edges are set and the centers no longer look wet and glossy.
Let cookies cool 10 minutes on pan, then transfer to wire rack to cool completely.
