Preheat your air fryer to 400°F (200°C).
Rinse the chickpeas thoroughly and pat them dry using paper towels. Removing excess moisture is crucial for achieving crispiness.
In a bowl, toss the chickpeas with olive oil until evenly coated.
Sprinkle salt, black pepper, garlic powder, and buffalo seasoning over the chickpeas, and toss again to ensure even seasoning.
Place the seasoned chickpeas in the air fryer basket in a single layer. Avoid overcrowding to allow for even cooking and crispiness.
Air fry the chickpeas at 400°F (200°C) for about 15 minutes, shaking the basket halfway through to ensure they cook evenly.
Once golden and crispy, remove the chickpeas from the air fryer and let them cool slightly before serving.
