01 - In a mixing bowl, combine buttermilk, garlic powder, paprika, salt, and black pepper. Add the chicken pieces, tossing to coat evenly. Cover and refrigerate for at least 30 minutes for optimal tenderness.
02 - In a separate bowl, whisk together all-purpose flour, corn starch, paprika, onion powder, cayenne pepper if desired, salt, and black pepper until fully combined.
03 - Pour vegetable oil into a deep frying pan or pot to a depth of at least 2 inches and heat to 350°F.
04 - Remove marinated chicken pieces from the bowl, letting excess marinade drain off. Dredge each piece thoroughly in the flour mixture, ensuring an even coating.
05 - Add coated chicken pieces to the hot oil in small batches. Fry for 3 to 4 minutes, turning as needed, until each is golden brown and cooked through. Transfer to paper towels to drain excess oil.
06 - Arrange chicken bites on a platter and serve hot with preferred dipping sauces such as ranch, honey mustard, or barbecue.
