Place bite-sized chunks of chicken in a bowl of buttermilk and hot sauce. Evenly coat each piece and then let the chicken marinate for 1 hour.
Combine breadcrumbs, flour, and seasonings on a plate. Then, coat each piece of chicken, pressing gently to ensure the breading sticks.
Fry the chicken in vegetable oil, cooking the bites in batches until they are golden brown and cooked through (about 5 minutes).
Let your chicken cool on paper towels so that excess oil is absorbed. After that, serve with ketchup or ranch and enjoy!
