DO NOT SKIP THIS STEP: First, add apple cider to a large pan and turn it to medium heat. Once bubbling, allow it to reduce for about 5-8 minutes, until there is ¾ cup of cider left. Transfer it to a measuring cup to make sure you have exactly ¾ cup - if you're slightly short, add a bit more fresh apple cider. Allow it to cool down. To expedite this, I like to pop it in the fridge. It's okay if it's slightly warm, but it shouldn't be hot.
1.5 cups fresh apple cider
Meanwhile, preheat your oven to 350F and grease two donut pans (12 cavities total) with cooking spray.
In a large bowl, add all of the dry ingredients and whisk until combined. Set aside.
1.5 cups gluten free 1-to-1 flour, 1 tsp cinnamon, ¼ tsp ground nutmeg, ¼ tsp kosher salt, 1.5 tsp baking powder, ½ tsp baking soda
In another large bowl, whisk together the egg, coconut sugar, applesauce, avocado oil and vanilla. Then, while whisking, slowly pour in the reduced (and cooled) apple cider.
1 large egg, ⅔ cup coconut sugar, ⅓ cup unsweetened applesauce, ¼ cup avocado oil, 1 tsp vanilla extract
Add dry ingredients to the wet ingredients and use a spatula to combine. Continue stirring until the batter is mostly smooth, but it's okay if there are a few small clumps remaining.
Use a spoon or a piping bag (or ziplock bag with the corner cut off) to fill the donut cavities with batter. They should be about ¾ of the way full.
Transfer donut pans to the oven to bake for 10 minutes.
While the donuts are baking, add the monkfruit (or cane sugar) and cinnamon to a shallow bowl and stir until combined. Set aside.
½ cup monkfruit sweetener, 1 tsp cinnamon
Once donuts are done baking, allow them to cool in the pan for about 3 minutes, before gently using a butter knife to pop them out and transfer to a wire cooling rack.
Immediately dunk each side of the donuts in the cinnamon sugar mixture. If you do it while the donuts are still warm, you don't need any melted butter to help them stick.
They will be very light, fluffy and fragile if you eat them fresh, but will dry out slightly and be more sturdy as they cool down. I like them most after about an hour of cooling! Store leftovers in an airtight container at room temperature for about 3 days. You may notice that the cinnamon sugar coating soaks into the donuts a bit.
