01 - In a mixing bowl, combine buttermilk, garlic powder, paprika, salt, and black pepper. Add the chicken pieces and toss to coat evenly. Cover and refrigerate for at least 30 minutes for optimal tenderness; marinating is optional but recommended.
02 - In a separate bowl, whisk together flour, cornstarch, paprika, onion powder, cayenne pepper (if desired), salt, and black pepper to create a well-blended dry coating.
03 - Heat vegetable oil in a deep frying pan or deep fryer to 350°F (175°C), ensuring there is sufficient oil for submerging the chicken pieces.
04 - Remove chicken pieces from the marinade, allowing excess liquid to drip off. Dredge each piece thoroughly in the flour mixture until fully coated.
05 - Fry chicken bites in batches for 3 to 4 minutes per batch, or until golden brown and cooked through. Avoid overcrowding the pan and maintain consistent oil temperature.
06 - Transfer cooked chicken bites to a plate lined with paper towels to absorb excess oil. Serve immediately with your preferred dipping sauce.
