01 - Whisk together buttermilk, garlic powder, paprika, salt, and black pepper in a bowl. Add chicken pieces and mix until well coated. Refrigerate for at least 30 minutes for enhanced tenderness, if time allows.
02 - In a separate bowl, blend all-purpose flour, corn starch, paprika, onion powder, cayenne pepper (optional), salt, and black pepper until evenly distributed.
03 - Pour vegetable oil into a deep frying pan or deep fryer, ensuring there is enough to fully submerge the chicken pieces. Heat oil to 350°F.
04 - Remove chicken pieces from the marinade, allowing excess liquid to drip off. Dredge each piece thoroughly in the flour mixture to ensure complete coverage.
05 - Fry coated chicken in small batches for 3 to 4 minutes per batch, turning occasionally, until golden brown and fully cooked. Transfer to paper towels to drain any excess oil.
06 - Arrange chicken bites on a platter and serve hot with a dipping sauce of choice.
