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 or up to 2 hours in refrigerator.
03 - Combine crushed cornflakes, panko breadcrumbs, smoked paprika, garlic powder, onion powder, and cayenne pepper in a shallow dish.
04 - Beat eggs and water together in a separate bowl.
05 - Remove chicken from marinade, letting excess drip off. Dip each piece first into egg wash, then press firmly into coating mixture, ensuring even coverage.
06 - Arrange coated chicken on prepared wire rack. Spray or brush lightly with oil for extra crispiness.
07 - Bake for 25-30 minutes until crust is golden and chicken is cooked through, reaching internal temperature of 165°F.
08 - Combine honey, hot sauce, apple cider vinegar, red pepper flakes, and salt in a small saucepan. Warm gently over low heat, stirring 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.
