Air Fryer Cinnamon Sugar Donuts
Why this recipe works
- Yeasted dough texture: A short rise gives the doughnuts a soft, airy crumb rather than the denser texture of cake-style doughnuts.
- Even golden finish: Air frying in a single layer helps the doughnuts puff and brown without deep frying.
- Coating that clings: Brushing the warm doughnuts with melted butter helps the cinnamon sugar stick while adding richness.
- Freezer-friendly option: Uncoated doughnuts can be frozen, reheated and finished with cinnamon sugar just before serving.

Timing notes
- Watch the dough, not just the clock: The first rise should leave the dough roughly doubled; a cool kitchen may need longer than the stated time.
- Best served warm: The coating is at its most fragrant and the crumb at its softest shortly after air frying.
- Same-day texture: These doughnuts are best on the day they are made, before the coating softens and the crumb firms up.
Texture tips
- Knead until elastic: A smooth, elastic dough helps the doughnuts puff evenly and gives a softer bite.
- Check the centres: The rings should be golden outside and cooked through in the middle; air fryer strength can vary.
- Cool for a firmer coating: Serve warm for a softer coating, or cool on a rack if you prefer the cinnamon sugar to set slightly.
Make-ahead tips
- Freeze before coating: Freeze the cooked doughnuts uncoated, then reheat and roll in cinnamon sugar once warm.
- Refresh before serving: Reheat cooled doughnuts in the air fryer at 160°C (320°F) for a few minutes, then refresh the coating.
- Keep the coating fresh: If storing, add or refresh the cinnamon sugar just before serving for the best texture.
Ingredient notes
- Use lukewarm milk: Milk that is warm rather than hot helps the yeast activate without slowing or damaging the rise.
- Instant yeast suits the quick method: Instant yeast can be mixed straight into the dough after a brief foamy start, keeping the process straightforward.
- Sugar changes the finish: Caster sugar gives a lightly crunchy coating, while icing sugar creates a softer, finer finish.

Instructions
- Pour the lukewarm milk into a mixing bowl, then whisk in the instant yeast and caster sugar. Leave for 5 minutes until slightly foamy.
- Whisk in the egg, vanilla extract and melted butter. Add the plain flour and salt, then mix to a shaggy dough and knead until smooth and elastic.
- Cover the bowl and leave the dough to rise until doubled in size. This should take about 45 minutes in a warm kitchen.
- Turn the dough out and roll it to about 1.5 cm thick. Cut into rings, then place on a tray and cover while you heat the air fryer to 180°C (355°F).
- Air fry the doughnuts in batches in a single layer for 5 to 6 minutes, turning halfway, until puffed and golden. Cook the centres until no longer doughy.
- Mix the caster sugar and ground cinnamon in a bowl. Brush the warm doughnuts all over with the melted butter, then roll in the cinnamon sugar until well coated.
- Serve warm, or cool on a rack if you prefer a firmer coating. Re-coat lightly in cinnamon sugar just before serving if needed.
Recipe notes
Tips
- Keep the milk just lukewarm so the yeast activates properly; if it is hot, it can slow the rise.
- Do not overcrowd the air fryer basket, as the doughnuts need room to puff and brown evenly.
- Food safety: if serving to pregnant people, young children, older adults, or anyone immunocompromised, use eggs that are produced under a food safety standard suitable for raw or lightly cooked preparations.
Substitutions
- Replace Vanilla extract with vanilla bean paste for a fuller vanilla note.
- Replace Caster sugar in the coating with icing sugar for a softer, less crunchy finish.
Storage
- Refrigerate up to 2 days
- Best eaten the day they are made. Store cooled doughnuts in an airtight container for up to 2 days; refresh in the air fryer at 160°C (320°F) for 2 to 3 minutes, then roll again in cinnamon sugar. Freeze uncoated doughnuts for up to 2 months and coat after reheating.
