1) Preheat the oven to 350°F. Lightly grease two standard donut pans. If you don't have doughnut pans, you can bake these in a standard muffin tin; they just won't be donuts.
2) Beat together the oil, eggs, sugar, pumpkin, spices, salt, and baking powder until smooth.
3) Add the flour, stirring just until smooth.
4) Fill the wells of the donut pans about 3/4 full; use a scant 1/4 cup of batter in each well.
5) Bake the donuts for 15 to 18 minutes, or until the center of one comes out clean.
6) Remove the donuts from the oven, and after about 5 minutes, loosen their edges, and transfer them to a rack to cool.
7) While the donuts are still warm, take your Simple glaze and brush the donuts. Then gently put them in a bag of cinnamon and sugar mixture.
8) Cool completely, and store (not wrapped tight) at room temperature for several days.
Yield: 12 doughnuts
