Prepare the Cauliflower:

Wash and cut the cauliflower into even-sized florets. Pat them dry with a paper towel.

Make the Batter:

In a mixing bowl, whisk together the flour, water, garlic powder, paprika, and salt until smooth.

Coat the Cauliflower:

Dip each cauliflower floret into the batter, letting any excess drip off. If using panko breadcrumbs, roll the battered florets in the breadcrumbs for added crunch.

Air Fry the Cauliflower:

Preheat your air fryer to 375°F (190°C). Arrange the coated florets in a single layer in the air fryer basket. Cook for 12–15 minutes, shaking the basket halfway through, until golden brown and crisp.

Prepare the Buffalo Sauce:

In a small bowl, mix the Buffalo sauce and melted butter.

Toss in Sauce:

Transfer the cooked cauliflower to a large bowl and toss gently with the Buffalo sauce until well coated.

Finish Cooking (Optional):

Return the sauced cauliflower to the air fryer for an additional 3–5 minutes to set the sauce and enhance the crispiness.
