Preheat the oven to 350 degrees. Grease a regular donut tin.
Add all of the ingredients into a blender and process until smooth. Pour the batter into the donut cavities (or a muffin tin) and bake for 17 minutes (for donuts) or 23 minutes (for muffins) or until the donuts/muffins are firm and browning on the edges. Pop out of the cavities and enjoy.
