Preheat oven to 350F. And line a large baking sheet with parchment paper.
In a large bowl mix together the pumpkin, molasses, vegetable oil, and water.
In another bowl whisk together the flour, baking powder, cinnamon, and baking soda. Gradually stir the dry ingredients into the wet ingredients stirring until dough forms. (add a little extra water if necessary)
Using a spoon – spoon out the dough, and roll into balls, like making meatballs. Placing them about an inch apart on the baking sheet. Flatten slightly with a fork like making peanut butter cookies.
