Put the chicken in a large mixing bowl, add the hot sauce, buttermilk, salt, and pepper, and stir to coat evenly. Cover and refrigerate for 8 hours, turning the chicken pieces several times.
Remove the chicken from the refrigerator. In a deep cast-iron skillet, heat the vegetable oil to 360?F.
Combine the flour and 2 teaspoons of the Creole seasoning in a large mixing bowl. Dredge several pieces of chicken at a time in the flour, coating evenly and shaking off any excess. Fry the chicken, 4 to 5 pieces at a time, in the hot oil until golden brown, about 6 minutes on each side. Drain on paper towels and sprinkle with the remaining 1 teaspoon Creole seasoning. Serve hot or at room temperature.
