In a small bowl, combine salt, pepper, garlic powder, onion powder.
Cut your chicken breast in half length-wise to create 4 even pieces of chicken. This makes the meat cook faster and stay moist.
Rub the spice mixture (salt, pepper, garlic powder, onion powder) all over each of the pieces of chicken. Make sure to coat both sides.
Set the chicken aside and in three different vessels, add 1 cup of flour in one, two eggs and 1/4 cup of milk into the second one, and 1/2 cup of Italian Breadcrumbs and 1/2 cup of Panko Breadcrumbs in the third one.
Take a piece of chicken and put into the flour first. Coat both sides. (tip, i gently shake the vessel then flip the chicken over and do the same to the other side.
Next, take the coated chicken and place into the milk/egg mixture and coat on both sides.
Lastly, put the chicken into the bread crumbs and coat both sides. Again, shaking the chicken on each side normally works out very well. If your not comfortable doing that, just use your fork or tongs to flip on each side.
In your electric skillet (set at 300 degrees), cast iron pan or nonstick frying pan, melt 1 tbsp of butter and 1 tbsp of olive oil and coat pan. Bring the oil/butter up to a high temperature and place your breaded chicken breast into the skillet. Fry for about 3 minutes on each side, making sure you have a nice golden brown color on both sides.
Remove the chicken breast from the frying pan/skillet and place on a platter lined with paper towels to absorb some of the grease.
Repeat the procedures above with all of the chicken breasts until you have fried all of them.
