Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a medium bowl, whisk together the dry ingredients: flour, pumpkin pie spice, baking powder, baking soda, and salt.

In a large bowl, whisk together the wet ingredients: oil, brown sugar, granulated sugar, egg, pumpkin puree, and vanilla extract until smooth and creamy.

Gently fold the dry ingredient mixture into the wet ingredients until just combined.

Prepare two bowls, one with granulated sugar and the other with powdered sugar for rolling the dough.

Scoop out portions of the dough, roll them in granulated sugar, and then in powdered sugar.

Place the sugar-coated dough balls on the prepared baking sheets, 2 inches apart.

Bake for 9-10 minutes until they puff and crack, then cool for a few minutes before transferring to a wire rack.
