Preheat the oven to 350. Lightly grease doughnut pan. Combine the oil, eggs, sugar, pumpkin, spices, salt, and baking powder. Mix until blended.
Bake the doughnuts for 18 minutes or until a toothpick inserted into the center comes out clean. Allow to cool in pan for 5 minutes then use a butter knife to gently loosen each from the pan.
