Preheat the oven to 365º F.
Lightly coat an 8x8x2-inch baking dish with nonstick cooking spray; set aside.
In a medium-sized bowl, combine the flour, cayenne pepper and salt.
Place the buttermilk and cornflake crumbs in two separate shallow bowls.
Roll the chicken breast halves in the flour mixture, coating evenly each side.
Next dip the chicken into buttermilk, and then into the cornflake crumbs.
Place the coated chicken breasts in the prepared baking dish.
Bake in the oven for about 20 minutes (until the chicken is tender and no longer pink).
One serving is approximately 150 grams
