Place chicken pieces in a large, shallow pan/dish. Pour buttermilk over and turn chicken pieces to coat evenly. Cover and refrigerate at least 2 hours.
Preheat oven to 375 degrees.
Place the oil and butter in another shallow pan (a jelly roll pan is perfect) and put in a heated 375 degree oven to melt. Set aside.
Drain chicken in colander to remove excess liquid. Pat chicken dry with paper towels.
In a large plastic bag, combine the flour and seasonings.
Roll the chicken in the melted butter/oil mixture, then drop into the bag and shape to cover.
Put chicken in a baking pan. Bake for 20 minutes. With a spatula, turn the chicken over and bake 5-10 minutes longer or until the top crust begins to bubble.
NOTE: You can adjust this recipe to use boneless, skinless chicken thighs, or chicken tenders. The total weight of boneless, skinless meat should equal 1 1/4 to 1 1/2 pounds. You will want to reduce the cooking time for chicken tenders since they are a thinner piece of meat and will cook much quicker then a chicken breast.____I listed cayenne pepper as an optional ingredient in this recipe. I like a spicy kick to fried chicken. I probably wouldn't add the cayenne pepper if I was serving it to children._____For the buttermilk: I've used both regular and the low-fat versions. Both work well in this recipe._____For night before prepping: Mix seasoning and flour and put in plastic bag. Put chicken to marinate in buttermilk. Measure out butter and vegetable oil-combine in small covered bowl.
