01 - In a mixing bowl, combine buttermilk, garlic powder, paprika, salt, and black pepper. Add chicken pieces and toss to coat evenly. Refrigerate for at least 30 minutes for enhanced tenderness, if time permits.
02 - In a separate bowl, blend all-purpose flour, corn starch, paprika, onion powder, cayenne pepper if using, salt, and black pepper.
03 - Fill a deep frying pan or pot with vegetable oil and heat to 350°F (175°C).
04 - Remove chicken from marinade, allowing excess liquid to drip off. Dredge each piece in the seasoned flour mixture, ensuring even coverage.
05 - Fry chicken bites in batches for 3 to 4 minutes per batch, or until golden brown and cooked through. Transfer to paper towels to drain excess oil.
06 - Serve hot accompanied by your preferred dipping sauces.
