Marinate the Chicken
In a bowl, combine buttermilk, hot sauce, garlic powder, paprika, salt, and pepper. Add chicken pieces and toss to coat. Cover and refrigerate for 30 minutes (or overnight for best flavor).
Prepare the Breading
Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper or a wire rack. In a shallow bowl, mix crushed cornflakes, panko, paprika, onion powder, cayenne, salt, and pepper.
Coat the Chicken
Remove chicken from marinade and shake off excess. Dredge each piece in the breading mixture, pressing to adhere well. Place on prepared baking sheet. Lightly spray tops with oil to help browning.
Bake Until Crispy
Bake for 22–25 minutes, flipping halfway through, until golden and crispy, and internal temp reaches 165°F (74°C).
Make the Hot Honey
While the chicken bakes, combine honey, hot sauce, red pepper flakes, and apple cider vinegar in a small saucepan. Warm over low heat for 2–3 minutes, stirring occasionally.
Drizzle and Serve
Remove chicken from oven and immediately drizzle or brush with hot honey. Serve warm with extra sauce on the side.
