01 - In a mixing bowl, combine buttermilk, garlic powder, paprika, salt, and black pepper. Add chicken pieces and toss to ensure even coating. Refrigerate for at least 30 minutes for optimal tenderness, if time permits.
02 - In a separate bowl, whisk together all-purpose flour, cornstarch, paprika, onion powder, cayenne pepper, salt, and black pepper until thoroughly combined.
03 - Pour vegetable oil into a deep frying pan or fryer to a depth suitable for submerging chicken pieces. Heat oil to 350°F.
04 - Remove chicken from marinade, allowing excess liquid to drip off. Dredge each piece in the flour mixture, ensuring entire surface is fully coated.
05 - Working in batches, place coated chicken pieces in hot oil. Fry for 3 to 4 minutes per batch, turning as needed, until golden brown and cooked through. Remove with a slotted spoon and drain on paper towels.
06 - Serve chicken bites hot with your preferred dipping sauce.
