Preheat oven to 375°F.
Remove skin, if any, from chicken pieces. If working with large chicken breasts, cut in half lengthwise for faster cooking time. Trim any excess fat.
In a medium bowl, crush cornflakes.
In a second medium bowl, mix flour, salt, and black pepper.
In a third medium bowl, add eggs and milk. Beat with a fork.
Dip each chicken piece into flour, then egg mixture, then cornflakes. Each piece should be fully coated with flakes.
Coat baking sheet with non-stick cooking spray. Place chicken pieces on sheet, evenly spaced. Spray pieces lightly with cooking spray.
Bake for 20–25 minutes, or until internal temperature reaches 165°F.
