01 - Combine buttermilk, garlic powder, paprika, salt, and black pepper in a mixing bowl. Add chicken pieces and turn to coat evenly. Cover and refrigerate at least 30 minutes for enhanced tenderness, if time allows.
02 - In a separate bowl, whisk together flour, corn starch, paprika, onion powder, cayenne pepper, salt, and black pepper until thoroughly combined.
03 - Pour vegetable oil into a deep fryer or large frying pan to a depth of about 2–3 inches. Heat oil to 350°F (175°C).
04 - Remove chicken from marinade and allow excess liquid to drip off. Dredge each piece in the breading mixture, coating completely and pressing to adhere.
05 - Working in batches, carefully place breaded chicken pieces in hot oil. Fry 3–4 minutes per batch, turning as needed, until golden brown and fully cooked. Use a slotted spoon to remove and drain on paper towels.
06 - Arrange cooked chicken bites on a platter and serve hot alongside your preferred dipping sauce.
