Mix the flour, egg, (or flax egg) wheat gluten, and, yeast in a large mixing bowl.
Add the coconut oil, (melted) sweetener, vanilla extract, and warm water. Mix until it becomes a nice dough. If using a food processor, process a minute more. If using a mixing bow, knead on a floured surface for a minute. Cover and put in a warm location to let it rise for 1 hour.
After it rises, knead it on a floured surface for another minute. Return to the bowl, cover, and let rise for another 15 minutes.
Roll out the dough on a floured surface, leaving it the thickness of your finger. Cut out small circles using a glass with flour on the rim, or a ring to a mason jar. (That's what I used) Cut out as many as you can, then repeat.
Put the donuts on cookie sheets with parchment paper, lightly floured, cover, and let rise in a warm spot again for 45-60 minutes.
When you have about 5 minutes left, preheat your air-fryer to 360F. Place your donuts in your air-fryer pan or a small pan you have leaving them spaced apart a few inches. Air-fry for 4 minutes, then put them on a cooling rack. Yes they look more like rolls or buns but believe me...they taste BOMB.COM!!
Continue the last step until you have air-fried all your donuts.
Slice them in half like you would a hamburger bun. Remove your pastry filling from the fridge and spoon about a tablespoon onto each donut, them place the top back on.
Place your chocolate and coconut oil in a microwave safe bowl and melt in the microwave in 30 second increments. Don't wanna burn your precious chocolate!! You'll want it runny.
Pour over your donuts and place in the fridge to harden the chocolate into a nice shell. Or if you're impatient like me, eat the as soon as you're done covering them all with chocolate.
Store in the fridge in an airtight container for up to 2 weeks. Then freeze...if there's any left!!
