Preheat and Prepare Pans: Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper or a silicone baking mat
Cream Butter and Sugar: In a large bowl, using a hand mixer or stand mixer, beat butter, granulated sugar, and brown sugar until light and fluffy, about 2–3 minutes.
Finish Wet Ingredients: Beat in pumpkin puree, egg, and vanilla extract until smooth and well combined.
Mix Dry Ingredients: In a separate bowl, whisk together flour, cream of tartar, baking soda, salt, cinnamon, nutmeg, ginger, and cloves.
Mix Wet and Dry Ingredients: Gradually add dry ingredients to wet ingredients, mixing until just combined. The dough will be soft.
Chill Dough: Cover and refrigerate for at least 1 hour to firm up.
Mix Topping and Scoop Dough: In a small bowl, stir together sugar and cinnamon for the coating. Using a 1½ Tbsp cookie scoop, scoop portions of dough and roll into balls.
Top Dough: Roll each ball in the cinnamon-sugar mixture to coat evenly. Place on prepared baking sheets, spacing 2 inches apart.
Bake: Bake for 12–14 minutes, until edges are lightly browned and set. Centrs should be puffed and slightly cracked.
Cool: Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
