How to Make It
Stir together cornstarch, powdered sugar, paprika, pepper and garlic powder in a shallow baking dish. Sprinkle chicken with 1/2 teaspoon salt. Dredge in cornstarch mixture, shaking off excess. Dip chicken in buttermilk, allowing excess to drip off. Toss chicken in cornflakes to coat.
Lightly spray air fryer basket with cooking spray. Place half of the chicken in single layer in the basket and spray with cooking spray. Cook at 400°F until golden brown and cooked through, about 8 minutes, turning chicken halfway through cook time. Remove chicken from fryer basket and sprinkle with 1/8 teaspoon salt. Repeat with remaining chicken pieces and salt.
