Preheat the oven to 425°F (for bone-in chicken) or 400°F (for boneless chicken). Place a rack on top of a large rimmed baking sheet that has been lined with aluminum foil. Spray rack with cooking spray and set aside. In a bowl, whisk together the mayonnaise, salt, seasoned salt, and garlic powder.
Pat the chicken dry, and season the meat liberally with salt and pepper.
Brush the chicken pieces with the mayonnaise mixture.
Coat each piece of chicken with the crushed Corn Flakes, pressing gently to help the crumbs adhere.
Arrange the chicken on the prepared baking sheet.
Bake bone-in chicken pieces in a 425°F oven for about 35-40 minutes, boneless chicken thighs in a 400°F oven for 20-25 minutes, or boneless chicken tenders in a 400°F oven for 12-15 minutes, until the chicken reaches an internal temperature of 165°F. If you're using larger bone-in chicken breasts, you will need to bake them for longer (about 45-50 minutes). If the crumb coating starts to get too dark while the chicken is roasting, just tent loosely with foil.
