01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper or a silicone baking mat.
02 - Whisk together flour, cornstarch, garlic powder, onion powder, smoked paprika, salt, and black pepper in a large bowl. Gradually add milk while whisking until a smooth, thick batter forms.
03 - Add cauliflower florets to the batter and toss until evenly coated.
04 - Place coated florets in a single layer on the prepared baking sheet, spacing them apart evenly.
05 - Bake for 20 minutes, flipping the florets halfway through to ensure even crisping.
06 - In a small bowl, combine hot sauce, melted butter, and honey or maple syrup if using. Mix well.
07 - Remove cauliflower from oven and carefully toss florets in the buffalo sauce until fully coated.
08 - Return sauced cauliflower to the baking sheet and bake for an additional 10 to 15 minutes until edges are crispy and lightly browned.
09 - Transfer to a serving dish, sprinkle with chopped parsley or chives if desired, and serve immediately.
