Preheat the oven to 350° degrees F. Grease two large cookie sheets or line with parchment paper. Set aside.
In a large bowl with an electric mixer, mix the butter, sugars, eggs and pumpkin. Mix on low speed until combined.
In a separate large bowl, whisk together flour, baking soda, baking powder, cinnamon, and nutmeg. Slowly add dry ingredients into the wet mixture a little bit at a time and mix until just combined. Stir in chocolate chips.
Drop the cookies onto the baking sheet with a cookie scoop or tablespoon. Bake for 12 to 15 minutes. Cool on a cooling rack. When cooled frost with frosting.
