Preheat oven to 375. Combine pumpkin, oil, sweetener, and orange flavoring in a medium bowl.
Add flour, baking soda, & seasonings. Mix just 'til combined.
Fold in nuts if using.
Make spoonfuls or scoops with a 2 Tbsp muffin scoop. If desired, roll in a bit of granulated sweetener before baking. You get a really nice "punch" of sweetness without adding a lot of sweetener when you coat cookies rather than adding more to the batter. :-P.
Place spoonfuls or scoops on a baking sheet (the scoops result in a cookie that really resembles the Enjoy Life ones :-)).
Bake 8-10 minutes or until lightly browned. They will harden a bit as they cool, but will still be nice and soft.
