I only copied this recipe so that you can see exactly what you are doing, with almost the exact same ingredients. My only guess is that the heat was too high when you pan seared the chicken, thereby making the crust too hard while the chicken inside wasn't cooking. Splitting your chicken breasts are a great idea, I'm assuming that you cut them in half length wise (horizontally) and not vertically. Also, try using Olive Oil and butter for more flavor and cook in a preheated pan on Medium to Medium High heat, at the very most. Covering your breaded chicken with tin foil in the oven will create a steaming affect and cause your breading to become soggy, if you have to use the oven, I would do an open baking method as apposed to covering it. I would split the chicken breasts horizontally and pan sear them, no need to turn on the oven. Anyways, I hope this helps you out today to enjoy your chicken and good for you to keep on trying it, until you get it right!
