01 - Combine buttermilk, garlic powder, paprika, salt, and black pepper in a mixing bowl. Add chicken pieces and toss to evenly coat. Cover and refrigerate for at least 30 minutes to enhance tenderness, if time allows.
02 - In a separate bowl, blend all-purpose flour, corn starch, paprika, onion powder, cayenne pepper (if desired), salt, and black pepper until thoroughly combined.
03 - Pour vegetable oil into a deep frying pan or Dutch oven to a depth of at least 2 inches. Heat oil to 350°F.
04 - Remove chicken from marinade, allowing excess to drip off. Dredge each piece thoroughly in the flour mixture, ensuring a complete coating.
05 - Fry chicken pieces in batches for 3 to 4 minutes per batch, turning as needed, until golden brown and the chicken is fully cooked. Avoid crowding the pan. Transfer to paper towels to drain excess oil.
06 - Arrange chicken bites on a platter and serve hot with preferred dipping sauces.
