Preheat oven to 350. Grease donut pans with non-stick spray. (This makes 18 but you can cook in batches.)
In a large mixing bowl, whisk together the flour, baking soda, baking powder, salt, pumpkin spice and cinnamon.
In a separate bowl, whisk together the brown and granulated sugar with the melted butter. Whisk in the canned pumpkin, then the eggs and the vanilla.
Add the wet ingredients to the dry ingredients and whisk until well combined.
Place the mixture in a gallon storage bag or piping bag, seal, then cut off 1/2 an inch off one corner of the bag to pipe through.
Gently pipe the mixture in to your prepared donut pans, about 3/4 of the way full.
Bake at 350 for 12-14 minutes or until just springy to the touch.
Remove from oven and let cool 2 minutes in the pan, then remove on to a cooling rack.
For the coating, whisk together the sugar, cinnamon and pumpkin spice in one small bowl. Melt the butter in a separate separate bowl.
Brush each donut all over with a small amount of butter and roll in the sugar/cinnamon/pumpkin spice mixture until coated! They are ready to serve!
