Two Ingredient Doughnut Bite

1. In a mixing bowl, combine the plain yogurt and self-raising flour. Mix until you have a smooth and slightly sticky dough. If the dough is too sticky, you can add a little more flour, but don't overdo it.
2. ‍‍Break off small pieces of dough and roll them into bite-sized balls, about 1 inch in diameter. You should have approximately 20-24 dough balls.
3. Place the dough balls in the preheated air fryer basket in a single layer, making sure they are not touching then cover them with a small amount of egg.
4. Air fry at 180 degrees Celsius for about 10 minutes or until the dough balls are golden brown and cooked through. You may need to work in batches depending on the size of your air fryer.
5. While the dough balls are cooking, prepare the cinnamon sugar coating. In a shallow bowl, mix together the caster sugar and ground cinnamon.
6. When the dough balls are done, immediately brush them with the melted butter and then roll them in the cinnamon sugar mixture to coat them evenly.

Serve:

1. Transfer the coated dough balls to a serving platter. They are best enjoyed warm, so serve them right away for a delightful treat.
