Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add in the pumpkin puree, egg, and vanilla extract, mixing until well combined.
In a separate bowl, whisk together the flour, baking powder, baking soda, pumpkin pie spice, and salt.
Gradually add the dry ingredients to the wet mixture, stirring until just combined. If using, fold in the white chocolate chips for an added sweetness.
Drop rounded tablespoons of the cookie dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake for 12-15 minutes, or until the edges are lightly golden and the centers look set but soft. Don’t overbake; the cookies will continue to firm up as they cool.
Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Once cooled, dust with additional pumpkin pie spice for an extra touch.
