Preheat the oven to 350ºF and generously grease a donut pan with melted coconut oil.
In a large mixing bowl, combine the oat flour, pumpkin, sugar, melted oil, cinnamon, ginger, cloves, salt, baking soda, vanilla, and vinegar and stir well until a uniform batter is formed.
Transfer the batter to a large plastic bag (or a piping bag for frosting) and cut off one of the bottom corners so that you can pipe the batter into the donut pan. Pipe the batter into the 6 donut wells-- this should use all of the batter completely.
Bake the donuts until they are lightly golden and feel firm to the touch, about 18 to 20 minutes. Cool for at least 15 minutes before removing them from the pan.
I think the donuts are easiest to remove by twisting them clockwise in the pan, to help loosen them. Then place a wire wrack or plate on top of the pan and flip it over so that the loosened donuts will release from the pan and fall on to the plate.
Top with extra coconut sugar or Maple Pecan Glaze and serve. Leftover donuts can be stored in an airtight container on the counter for up to 3 days, or in the fridge for up to 2 weeks.
