01 - In a mixing bowl, whisk together buttermilk, garlic powder, paprika, salt, and black pepper. Add chicken pieces and turn to coat evenly. Cover and refrigerate for at least 30 minutes for best results.
02 - In a separate bowl, combine all-purpose flour, corn starch, paprika, onion powder, cayenne pepper if desired, salt, and black pepper. Mix thoroughly to ensure even distribution.
03 - Pour vegetable oil into a deep frying pan or deep fryer to a depth suitable for submerging chicken pieces. Heat oil to 350°F.
04 - Remove chicken from the marinade and allow excess liquid to drain. Dredge each piece thoroughly in the flour mixture to ensure an even coating.
05 - Working in batches, fry coated chicken bites for 3 to 4 minutes per batch, until golden brown, crisp, and fully cooked. Remove using a slotted spoon and transfer to a paper towel–lined plate to drain excess oil.
06 - Present chicken bites hot, accompanied by your choice of dipping sauce.
