Preheat your oven to 325 degrees Fahrenheit and prepare your donut pan.

To make the apple donuts, add the almond flour, oat flour, baking soda, baking powder, cinnamon, nutmeg, and sea salt to a small bowl. Stir until combined. Add the maple syrup, apple sauce, coconut oil, apple cider vinegar, and vanilla and stir until smooth. Spoon the mixture into your donut pan. You should have 6-7 donuts depending on the size of your pan.

Bake in your preheated oven for 33-36 minutes, until golden on top and slightly soft. Let the donuts cool completely before removing from the pan. I suggest even leaving them in the fridge for a few hours or overnight so the donuts are set and don't break when you remove them from the pan.

Once your donuts are removed from the pan, prepare the cinnamon sugar by adding the cinnamon and coconut sugar on a plate. Set aside. Lightly brush the donuts with the prepared melted coconut oil. Coat the donuts in the cinnamon sugar mixture and gently tap to remove excess sugar. Enjoy immediately or store in the fridge.
