Preheat your oven to 450°F (232°C).
In a large bowl, whisk together the flour, water, garlic powder, onion powder, paprika, salt, and pepper until smooth.
Dip each cauliflower floret into the batter, ensuring they are well coated.
Place the battered florets on a baking sheet lined with parchment paper.
Bake in the preheated oven for 20 minutes until golden and crispy.
While the cauliflower bakes, mix the buffalo sauce with olive oil in a bowl.
Remove the cauliflower from the oven and toss it in the buffalo sauce mixture.
Return the coated cauliflower to the baking sheet.
Bake for an additional 10 minutes to allow the sauce to set.
Serve immediately and enjoy!
