Preheat oven to 375 degrees F.
In a bowl, whisk together dry ingredients until evenly combined.
In another bowl, combine all wet ingredients except coconut oil. Mix.
Once wet ingredients are fully mixed, stir into bowl of dry ingredients and combine. Note - the donut batter may fizz up a little, that's just the baking soda reacting with the apple cider vinegar!
After stirring for a bit, add in the melted coconut oil and stir in completely.
Spray your donut pan with coconut oil or another nonstick spray.
Pour batter evenly between 6 donut molds.
Bake donuts in the oven for 15 minutes. Once done, let cool for a few minutes.
While donuts are cooling, combine turbinado sugar and cinnamon in a high-speed blender, spice grinder, or coffee grinder. Blend until sugar is a fairly powdered consistency.
Once donuts are cooled, toss in cinnamon sugar.
Enjoy!
