Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone baking mat.
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy, about 2-3 minutes.
Add the egg, pumpkin puree, and vanilla extract to the butter mixture. Beat until well combined.
In a separate bowl, whisk together the flour, baking soda, cinnamon, nutmeg, ginger, cloves, and salt.
Gradually add the dry ingredients to the wet ingredients and mix until combined.
If desired, fold in chocolate chips or chopped walnuts for added flavor and texture.
Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake for 10-12 minutes, or until the edges are golden and the centers are just set. Be careful not to overbake for a soft, chewy texture.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
