01 - In a large mixing bowl, whisk together buttermilk, garlic powder, paprika, salt, and black pepper. Add chicken pieces and evenly coat. Cover and refrigerate for at least 30 minutes for optimal tenderness.
02 - In a separate bowl, stir together all-purpose flour, corn starch, paprika, onion powder, cayenne pepper (if using), salt, and black pepper until evenly blended.
03 - Pour vegetable oil into a deep frying pan or pot to a depth of at least 5 centimeters (2 inches) and heat to 350°F.
04 - Remove chicken pieces from the marinade, letting excess marinade drip off. Dredge each piece thoroughly in the flour mixture, ensuring complete coverage.
05 - Working in batches, fry coated chicken for 3–4 minutes per batch, turning occasionally, until golden brown and cooked through. Transfer to a plate lined with paper towels to drain excess oil.
06 - Present hot chicken bites with your choice of dipping sauce.
