In a large mixing bowl, combine 140 g of self-raising flour and 140 g of sweetened Greek yogurt. Stir until a soft dough forms.

Transfer the dough to a lightly floured surface and knead gently for about 2 minutes until smooth and elastic.

Divide the dough into two equal portions, rolling each into a log approximately 1 inch thick and cut into small pieces weighing 8-12g.

Preheat your air fryer to 180°C (350°F) for about 5 minutes and brush the basket with oil.

Toss the shaped balls in melted butter and place them in the air fryer basket, air frying for 5 minutes.

Remove the Air Fryer Donut Bites when done and coat them in melted butter and cinnamon-sugar mixture.
