Gently blot any moisture off the chicken wings using paper towels to ensure they are thoroughly dry.
Divide the wings into drumettes and wingettes using kitchen shears or a sharp blade, if not already segmented.
In a large bowl, combine the all-purpose flour, cornstarch, baking powder, smoked paprika, dried parsley, salt, garlic powder, onion powder, black pepper, and cayenne (if using). Mix until evenly blended.
Toss the chicken wings in the dry mixture, ensuring each piece is thoroughly coated. Shake off any excess flour mixture before frying.
Pour oil into a deep pot or heavy-bottomed pan to a depth of about one inch. Set over medium-high heat and allow it to reach 350°F (175°C).
Carefully add the coated wings into the hot oil in batches, avoiding overcrowding. Fry for 8 to 10 minutes, turning occasionally, until the exterior is golden brown and crisp.
Transfer the fried wings to a wire rack set over paper towels to drain any remaining oil.
