Set oven to 350°F (175°C) and line baking sheets with parchment.
Beat butter and 1 cup sugar until light and fluffy.
Mix in egg, pumpkin puree, and vanilla until smooth.
Whisk flour, baking soda, baking powder, salt, cinnamon, ginger, nutmeg, and cloves in a separate bowl.
Stir dry mixture into wet mixture until a soft dough forms; if too sticky, add flour 1 tablespoon at a time.
Combine ¼ cup sugar with ½ teaspoon cinnamon, then roll tablespoon-sized dough balls in mixture.
Arrange 2 inches apart on baking sheets and bake 10–12 minutes, until edges set and tops are lightly golden.
Cool 5 minutes on the sheet, then transfer to a wire rack.
