Preheat oven to 350°F (175°C). Line a baking sheet with parchment or a silicone mat.
Beat butter, ¼ cup sugar, and brown sugar until light and fluffy, 2–3 minutes.
Mix in pumpkin, egg yolk, and vanilla until smooth.
Whisk flour, baking powder, baking soda, salt, cinnamon, nutmeg, ginger, and cloves.
Add dry ingredients to wet, mixing on low just until combined.
Scoop 1.5-tablespoon balls, roll in ¼ cup sugar to coat.
Arrange 2 inches apart. Bake 10–12 minutes, until edges set and centers soft.
Cool 5 minutes on sheet, then transfer to a wire rack. Serve warm or at room temp.
