In a medium size bowl, cream the butter, sugar, brown sugar and vanilla together. Add in the egg yolk and pumpkin pure and stir just until combined. Sift in the flour, cinnamon, ginger, nutmeg, cloves, salt, baking soda, and baking powder. Mix until a stiff batter appears.
In a small bowl, toss together the cinnamon and sugar for coating.
Scoop out 2 tablespoons of dough and roll into a ball, toss into the sugar and cinnamon mixture and place 2 inches apart on a cookie sheet.
