01 - Preheat oven to 425°F. Line a baking sheet with parchment paper and place a wire rack on top.
02 - Whisk buttermilk, salt, and black pepper in a large bowl. Add chicken breasts, turn to coat thoroughly. Marinate for at least 15 minutes, up to 2 hours refrigerated for enhanced flavor.
03 - Combine crushed cornflakes, panko breadcrumbs, smoked paprika, garlic powder, onion powder, and cayenne pepper in a shallow dish. Mix well to distribute spices evenly.
04 - Beat eggs with water 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 coating mixture, ensuring complete and even coverage on all sides.
06 - Place coated chicken on prepared wire rack. Lightly spray or brush with oil to promote extra crispiness.
07 - Bake for 25-30 minutes until crust is deep golden and chicken is cooked through, reaching 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. Avoid boiling.
09 - Remove chicken from oven and let rest for 5 minutes. Generously drizzle with hot honey immediately before serving.
