Preheat oven to 350°F. Line or spray large baking sheets. In a large bowl of mixer, combine pumpkin, sugars, oil, and vanilla and mix until smooth, 1-2 minutes. Add egg and mix again. In a medium bowl, whisk together flour, baking powder, salt, and spices. Dissolve baking soda with milk and stir in.

Add dry ingredients to batter and mix for just a couple seconds. With streaks of flour still remaining, add the chocolate chips and mix until combined. Drop cookie batter with cookie scoop onto baking sheets. Bake 10-12 minutes or until lightly brown and firm.
