Preheat your oven to 450°F (230°C).
In a bowl, whisk together flour, water, garlic powder, onion powder, paprika, and salt until smooth.
Dip each cauliflower floret into the batter, ensuring they are well-coated.
Place the coated florets on a baking sheet lined with parchment paper.
Spray the florets lightly with olive oil.
Bake for 20 minutes, flipping halfway through until golden and crispy.
In a separate bowl, combine the baked cauliflower with buffalo sauce, tossing to coat evenly.
Return the coated cauliflower to the baking sheet.
Bake for an additional 10 minutes to crisp up the sauce.
Serve hot with your favorite dipping sauce.
