01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper and lightly coat with cooking spray or brush with olive oil.
02 - In a large bowl, whisk together flour, garlic powder, smoked paprika, salt, and pepper. Gradually whisk in milk until smooth batter forms.
03 - Dip each cauliflower floret into batter, allowing excess to drip off, then press into panko breadcrumbs to coat evenly. Arrange coated florets on prepared baking sheet in single layer.
04 - Lightly spray or drizzle coated florets with oil. Bake for 20 minutes, turning halfway through, until golden brown and crispy.
05 - While cauliflower bakes, whisk together hot sauce, melted butter, and honey or maple syrup (if using) in small bowl until combined.
06 - Remove cauliflower from oven and transfer to large bowl. Pour buffalo sauce over hot florets and gently toss until evenly coated.
07 - Return coated cauliflower to baking sheet and bake additional 10 minutes until sauce is caramelized and exterior is crispy.
08 - Whisk together mayonnaise, sour cream or Greek yogurt, buttermilk or milk, dill, chives, parsley, minced garlic, onion powder, salt, pepper, and lemon juice in bowl. Adjust consistency with additional milk if needed.
09 - Serve crispy buffalo cauliflower bites immediately with ranch dressing on side for dipping.
