Preheat oven to 375.
Lightly grease cookie sheet.
If desired, once the oven is preheated, toast the chopped pecans in the oven for 5-10 minutes before adding them to the cookies.
Combine the sweetener and cinnamon in a small bowl for the Cinnamon Sugar Topping and set aside.
Combine pumpkin, oil, sweetener, vanilla and water in a medium bowl.
Place all dry ingredients except nuts in a large mixing bowl. Mix well until combined.
Add wet ingredients to dry.
Fold the pecans into the batter. Stir but do not use an electric mixer.
Roll 1-2 tablespoon scoops of dough into balls. Roll each ball into the cinnamon sugar mixture. Continue until all the dough has been used.
Place the rolled balls on a baking sheet about 2 inches apart.
Bake 8-10 minutes or until lightly browned. They will harden a bit as they cool, but will still be nice and soft.
Let the cookies cool for at least 3 minutes before removing them from the baking sheet, then transfer them to a cooling rack and allow to cool to room temperature.
Store in an airtight container.
