- Whip up the dough: 
- In a mixing bowl, stir together the flour, yogurt, baking powder, and vanilla flavour until a soft dough begins to form. If the mixture feels a bit sticky, sprinkle in a touch more flour until it’s easy to handle. 
- Shape the doughnuts: 
- Roll the dough out on a lightly floured surface. Using a round cutter (or even a cup!), cut out doughnut shapes, then use a smaller cutter to make the hole in the centre. 
- Bake to golden perfection: 
- Lightly brush each doughnut with a little oil or melted butter. Pop them into your air fryer at 180 °C for about 10 minutes, checking often to ensure they don’t overbake. 
- Mix the glaze: 
- In a small bowl, combine the icing sugar with just enough water to make a smooth, glossy icing. Stir in a few drops of orange food colouring and a splash of caramel flavour to taste. 
- Decorate & devour: 
- Once the doughnuts have cooled completely, dip them into the icing and then press them gently into the Halloween sugar strands sprinkles for a spooky-sweet finish.
