01 - Preheat oven to 425°F. Line a baking sheet with parchment paper and set a wire rack on top.
02 - Whisk buttermilk, salt, and black pepper in a large bowl. Add chicken breasts, turning to coat thoroughly. Marinate for at least 15 minutes, up to 2 hours refrigerated for deeper flavor penetration.
03 - Combine crushed cornflakes, panko breadcrumbs, smoked paprika, garlic powder, onion powder, and cayenne pepper in a shallow dish. Mix evenly.
04 - Beat eggs and water together in a separate bowl until fully incorporated.
05 - Remove chicken from marinade, allowing excess to drip off. Dip each piece into egg wash, then press firmly into the coating mixture, ensuring complete and even coverage on all sides.
06 - Place coated chicken on the prepared wire rack. Lightly spray or brush with oil to enhance crispiness.
07 - Bake for 25–30 minutes until crust is golden brown and chicken reaches internal temperature of 165°F.
08 - While chicken bakes, combine honey, hot sauce, apple cider vinegar, red pepper flakes, and salt in a small saucepan. Warm gently over low heat, stirring constantly until smooth and slightly pourable. Do not boil.
09 - Remove chicken from oven and let rest for 5 minutes to retain juices. Drizzle generously with hot honey immediately before serving.
