01 - Preheat oven to 425°F. Line a baking sheet with parchment paper and place a wire rack on top for air circulation.
02 - In a large bowl, whisk buttermilk, salt, and black pepper until combined. Add chicken breasts and turn to coat completely. Marinate for at least 15 minutes, or up to 2 hours in the refrigerator for deeper flavor penetration.
03 - Combine crushed cornflakes, panko breadcrumbs, smoked paprika, garlic powder, onion powder, and cayenne pepper in a shallow dish. Mix thoroughly to distribute spices evenly throughout the coating mixture.
04 - In a separate bowl, beat eggs and water together until fully blended. This creates a light egg wash that helps the coating adhere to the chicken.
05 - Remove chicken from the buttermilk marinade, allowing excess liquid to drip off. Dip each piece first into the egg wash, then press firmly into the crunchy coating mixture. Ensure an even, thorough layer covers all sides of the chicken.
06 - Place coated chicken pieces on the prepared wire rack. Spray or brush lightly with oil to promote extra crispiness and golden browning during baking.
07 - Bake for 25-30 minutes until the coating is deep golden and crispy, and the chicken is cooked through. Internal temperature should reach 165°F when measured with a meat thermometer.
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 to preserve honey's texture.
09 - Remove chicken from the oven and let rest for 5 minutes to allow juices to redistribute. Drizzle generously with warm hot honey sauce immediately before serving.
