Preheat your oven to 450°F.
In a small bowl, mix together the ingredients for the bang bang sauce: mayonnaise, sweet chili sauce, minced garlic, rice vinegar, sriracha, and chopped parsley. Set the sauce aside.
In a mixing bowl, combine buttermilk, cornstarch, all-purpose flour, chili powder, garlic powder, paprika, salt, and black pepper to create a thick batter.
Add the cauliflower florets to the batter, ensuring they’re evenly coated. Then, add the panko breadcrumbs and mix again.
Line a baking sheet with parchment paper and arrange the battered cauliflower florets, making sure they’re not touching.
Bake in the preheated oven for 20 minutes. Then, flip each floret over and bake for an additional 15 minutes until they turn golden and crispy.
Once out of the oven, transfer the cauliflower to a bowl and toss them with the bang bang sauce. If you prefer extra crispy cauliflower, simply dip them into the sauce instead of tossing.
Garnish with sliced scallions and dig in! These Bang Bang Cauliflower bites are irresistible.
