In a medium bowl, mix the flour, cinnamon, pumpkin pie spice, baking powder, baking soda, and salt. Set aside. Place the pumpkin puree on a plate. Press paper towel on the pumpkin. Do this 4 times to take out the moisture.

Preheat the oven to 350℉. Line two cookie sheets with parchment paper. Let the cookie dough sit for 10 minutes before scooping.
Use a large cookie scoop to scoop the dough. Place 6 cookie dough balls per cookie sheet. Use your hands to flatten the cookie dough slightly.
Bake for 13-15 minutes. Bake until the edges are golden brown. Let the cookies sit on the hot pan for 5 minutes before transferring to a cooling rack. These cookie taste best when cold.
