01 - Preheat your air fryer to 400°F for 5 minutes to ensure proper cooking temperature.
02 - In a large bowl, whisk together the flour, water, garlic powder, onion powder, smoked paprika, salt, and pepper until you have a smooth batter with no lumps.
03 - Add the cauliflower florets to the batter, tossing until evenly coated. Shake off excess batter to prevent sogginess.
04 - Arrange florets in a single layer in the air fryer basket. Work in batches if necessary to avoid overcrowding. Air fry for 12–15 minutes, shaking the basket halfway through, until golden and crisp.
05 - Meanwhile, in a small bowl, mix hot sauce, melted butter, and honey or maple syrup if using until well combined.
06 - Transfer cooked cauliflower to a clean bowl, drizzle with buffalo sauce, and toss to coat evenly.
07 - Return sauced cauliflower to the air fryer for another 3–5 minutes to set the sauce and crisp further.
08 - Serve immediately with celery sticks and blue cheese or ranch dressing if desired.
