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. Marinate for at least 15 minutes, up to 2 hours in refrigerator for enhanced flavor.
03 - Combine crushed cornflakes, panko breadcrumbs, smoked paprika, garlic powder, onion powder, and cayenne pepper in a shallow dish. Mix thoroughly.
04 - Beat eggs and water together in a separate bowl until well combined.
05 - Remove chicken from marinade, allowing excess to drip off. Dip each piece into egg wash, then press firmly into crunchy coating, ensuring even coverage on all sides.
06 - Place coated chicken on prepared wire rack. Lightly spray or brush with oil for extra crispiness.
07 - Bake for 25-30 minutes until crust is golden and chicken reaches internal temperature of 165°F.
08 - Combine honey, hot sauce, apple cider vinegar, red pepper flakes, and salt in small saucepan. Warm over low heat, stirring constantly until smooth and slightly runny. Do not boil.
09 - Remove chicken from oven and let rest for 5 minutes. Drizzle generously with hot honey before serving.
