Instead of buttermilk, I used Ranch dressing from a bottle, to dip the chicken into, NO Egg whites needed, and I crushed the cornflakes to a finer grade, using a large zip-lock baggie, and just used the heel of my hand to crush it. Also added 1 cup of flour right in the bag, and added the chicken pieces right into the bag. Make sure you tap the crust so it adheres well.
Most importantly, I replaced the boneless chicken thighs like the recipe mentions, and got with the skin, and bone in. A lot cheaper with bone and skin on. I removed the skin, of course. Baked it for additional 10 minutes in the Le Creuset cast iron glazed skillet. I only baked 4 pieces, and will make an additional for the next day, or freeze it!
