Preheat oven to 375 degrees. Line 2 baking sheets with parchment for easy cleanup.
In a large bowl, blend sugar and butter. Add egg & pumpkin until well combined.
Add flour, baking soda, baking powder, cinnamon and salt. Mix until combined, then add chocolate chips and nuts (if desired) by hand.
Drop by spoonfuls onto a baking sheet. Use wet fingers or a measuring cup dipped in water or sprayed with cooking oil to flatten the cookies and shape them if you wish. They don't spread much and will remain close to the shape you put them in the oven.
Bake until slightly browned on top, approximately 10-13 minutes. Let cool for 5-10 minutes. Enjoy!!!
