Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.
In a medium bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, nutmeg, cloves, and ginger. Set aside.
In a large bowl, beat the softened butter, granulated sugar, and brown sugar with an electric mixer on medium speed until light and fluffy, about 2-3 minutes. Add the egg, pumpkin puree, and vanilla extract, and mix until well combined.
Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. If using, fold in the white chocolate chips or chopped pecans with a spatula.
Scoop tablespoon-sized portions of dough onto the prepared baking sheets, spacing them about 2 inches apart. Flatten each slightly with the back of a spoon or your fingers for even baking.
Bake in the preheated oven for 10-12 minutes, or until the edges are set and the centers are still soft. Let the cookies cool on the baking sheets for 5 minutes before transferring to a wire rack to cool completely. Serve and enjoy your pumpkin spice cookies!
