01 - Preheat air fryer to 400°F for 5 minutes to ensure proper cooking temperature.
02 - In a large bowl, whisk together flour, water, garlic powder, onion powder, smoked paprika, salt, and black pepper until smooth batter forms.
03 - Add cauliflower florets to batter, tossing until evenly coated. Shake off excess batter.
04 - Arrange coated florets in single layer in air fryer basket. Cook in batches if necessary to prevent overcrowding. Air fry for 12-15 minutes, shaking basket halfway through, until golden and crispy.

06 - Transfer cooked cauliflower to clean bowl. Drizzle with buffalo sauce mixture and toss until evenly coated.
07 - Return sauced cauliflower to air fryer and cook for additional 3-5 minutes to set sauce and achieve final crispiness.
08 - Serve immediately with celery sticks and blue cheese or ranch dressing if desired.
