Mix the active dry yeast, warm water, oat milk and the tbsp of honey in a bowl. Set it aside for about 5 to 10 minutes until the yeast mixture becomes frothy
Sift the flours and add the rest of dry ingredients (lemon zest, salt, stevia powder)
Add the coconut oil, vanilla extract, date paste and eggs
Add the yeast mixture and mix it all together till you get a slightly sticky dough
Place it in a bowl, cover it with a kitchen towel or cling film and wait for at least 1 hour. The dough should almost double its size
Spread some oat flour over a clean surface, split the dough into 4 parts and roll them out to about 1.5 cm of thickness. Use a glass or a donut cutter to cut out the donut shapes
Repeat the same process with the remaining dough
Preheat the air fryer at maximum temperature
Place the donuts in the air fryer basket and spray some coconut or olive oil on them
Place them in the air fryer and bake for 8-10 minutes at 160ºC (320ºF)
If you choose to dip them into chocolate, it's time to melt the chocolate with 1 tbsp of coconut oil (instructions at the end of this recipe)
Dip one side of the donuts one by one into the melted chocolate and spread some chopped nuts on top
