Preheat oven to 350 degrees and prepare cookie sheet by spraying well with cooking spray, lining with parchment paper or using silicone baking sheet.
Cream butter and granulated sugar together in a large mixing bowl until light and fluffy.
Beat in egg, pumpkin and vanilla until well-blended.
Whisk together the flour, baking powder, baking soda, salt, cinnamon, nutmeg and cloves together in medium bowl and then add 1/3 at a time to creamed mixture, mixing after each addition. This will keep the dry ingredients from going all over your mixing area. If using a mixer, blend the dry ingredients into the wet ingredients at a low speed. Mix until just blended.
Add the chocolate chips and fold into the cookie mixture. (You may also add a cup of chopped walnuts, pecans or almonds if desired.)
Drop cookies onto prepared cookie sheet with a large (3 tablespoon) cookie scoop. Place 8 scoops of cookie dough well-spaced onto the cookie sheet. Push a couple of extra chocolate chips into the top of the unbaked cookies before baking.
Bake cookies at 350 degrees for 13-15 minutes or until cookies are slightly brown. Let cookies cool for 1-2 minutes on the cookie sheet before removing them to a cooling rack.
Makes 32 large cookies. Serving size is 1 large cookie.
