Preheat oven to 350°F. Line a cupcake pan with cupcake liners. Set aside.
In a large mixing bowl, whisk together all purpose flour, baking powder, baking soda, salt, ground cinnamon and pumpkin spice. Set aside.
In a separate, medium bowl, whisk together the pumpkin puree, eggs, vegetable oil, granulated sugar, brown sugar and vanilla extract until smooth and combined.
Fold the wet ingredients in with the dry ingredients until no streaks of flour remain. Do not overmix.
Evenly divide the batter between the liners. Bake for 18 to 20 minutes in the center of the oven or until the cupcakes have risen and spring back when touched. An inserted toothpick should come out clean or with a few moist crumbs.
Transfer cupcakes to a wire rack to cool completely.
