01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper or a silicone baking mat.
02 - In a large bowl, whisk together all-purpose flour, cornstarch, garlic powder, onion powder, smoked paprika, salt, and black pepper. Gradually whisk in milk until a smooth, thick batter forms.
03 - Toss cauliflower florets in the batter until evenly coated.
04 - Place coated florets in a single layer on the prepared baking sheet, spaced evenly apart.
05 - Bake for 20 minutes, flipping florets halfway through to ensure even crisping.
06 - Meanwhile, combine hot sauce, melted butter, and optional honey or maple syrup in a small bowl.
07 - Remove cauliflower from oven and gently toss florets in buffalo sauce to coat thoroughly.
08 - Return coated florets to the baking sheet and bake for 10 to 15 minutes until edges are crispy and lightly browned.
09 - Transfer to a platter, garnish with fresh parsley or chives if desired, and serve immediately.
