Pre-heat the oven to 350 degrees. This recipe makes about 9 donuts in my silcone donut pan. I do not spray the pan before baking - if you are using a different kind of donut pan, you may need to spray the pan with avocado oil spray to prevent sticking. My popped right out of the silicone donut pan. Whisk the flour, coconut sugar, baking powder, baking soda, salt, and cinnamon in a medium mixing bowl.
Add the applesauce, coconut milk, avocado oil, vanilla extract, and apple cider vinegar, and mix to combine.
Snip the tip of a piping bag or Zip Top bag to make a thick circle for the batter to come out of. Scoop the batter into the piping bag, and pipe the batter into the donut pan. I filled my silicone molds up to the top. Bake the donuts at 350 degrees for 25 minutes, or until a toothpick comes out clean and the tops are golden.
Let the donuts cool for a few minutes before turning them out onto a cooling rack to cool completely before coating in the cinnamon sugar.
