Drain and rinse the canned chickpeas under cold water and dry thoroughly with a kitchen towel.

In a large bowl, combine dried chickpeas with olive oil, sugar, cinnamon, and salt. Toss until well coated.

Preheat air fryer to 390°F (199°C) for about 3-5 minutes.

Spread seasoned chickpeas in a single layer in the air fryer basket and cook for 12-15 minutes, shaking the basket at the 6-minute mark.

Remove from air fryer and allow to cool slightly on a plate or bowl before serving.
