01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, nutmeg, ginger, and cloves until well blended.
03 - In a large bowl, beat the granulated sugar, brown sugar, and softened butter until light and fluffy, approximately 2-3 minutes.
04 - Mix in the pumpkin purée, egg, and vanilla extract until fully combined and smooth.
05 - Gradually add the dry ingredients to the wet mixture, mixing just until incorporated. Do not overmix.
06 - Fold in chocolate chips or nuts if desired.
07 - Drop the dough by rounded tablespoons onto the prepared baking sheets, spacing about 2 inches apart to allow for spreading.
08 - Bake for 11-13 minutes, or until the edges are set and the tops appear dry.
09 - Let the cookies rest on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
