01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper and lightly brush or spray with olive oil.
02 - In a large bowl, whisk together flour, garlic powder, smoked paprika, salt, and black pepper. Add milk and whisk until a smooth batter forms.
03 - Add cauliflower florets to the batter, tossing to coat evenly. Shake off excess batter and arrange florets in a single layer on the prepared baking sheet.
04 - Bake for 20 minutes, turning halfway, until cauliflower is starting to brown and crisp.
05 - Remove from oven. Using tongs, gently toss baked florets in a bowl with buffalo sauce until well coated. Return to the baking sheet and bake for another 12–15 minutes, until edges are crispy and sauce is slightly caramelized.
06 - While wings bake, prepare the blue cheese dip: In a small bowl, combine sour cream, mayonnaise, blue cheese, lemon juice, milk, black pepper, and chives. Stir until well mixed and creamy. Chill until ready to serve.
07 - Serve buffalo cauliflower wings hot with blue cheese dip, celery, and carrot sticks.
