While the air fryer is preheating, take a large bowl and combine the wet ingredients (coconut oil, apple sauce, honey, and vanilla). Mix the ingredients together until mostly combined.
Add all of the dry ingredients to the bowl of wet ingredients (flour, sugar, baking powder, sugar, and salt) and mix until combined.
Once the air fryer is done preheating, spray the basket with nonstick cooking spray. Take about 1 Tablespoon of dough at a time and roll it in your palms until it forms a small donut hole shape. Place donut holes in the air fryer, making sure to leave space in between and not overcrowd the basket. You can always cook it in two batches if necessary.
Air-fry the donut holes for 6 minutes total. After 3 minutes, use tongs to flip each donut hole to the other side and then cook for the remaining 3 minutes.
Take the powdered sugar and place it into a large bowl. Once the donuts are done cooking, use a tong to place them directly into the bowl of powdered sugar and toss until they have been evenly coated. The sugar will stick to the donuts best while they are still warm.
Place on a cooling rack for 5-10 minutes and enjoy!
Notes
The dough can get very sticking while shaping the donut holes! This is normal. To help with this, you can coat your palms with a bit of flour to help prevent your hands from getting too sticky. You can also refrigerate the dough for 30 minutes prior to shaping the donut holes.
Storage Instructions:
These donuts are best enjoyed fresh, but they can be stored in an air-tight container or Ziploc bag at room temperature for up to 3 days. If you prefer them warm, you can heat them up in the microwave for 15 seconds.
