Preheat an oven to 400F and line a baking sheet with a wire rack if possible. Or if you're using an air fryer, spray the basket with nonstick cooking spray.

 Coat chicken with honey and mustard so it can marinate for a few minutes while preparing the other ingredients. In a large zip-top bag, add cornflakes, salt, pepper, garlic powder and paprika. Seal shut. Using a rolling pin or bottle, crush cornflakes inside bag leaving them somewhat coarse. Transfer crushed cornflakes to a shallow dish.

Coat marinaded chicken in crumbs, place on prepared sheet pan, spray with cooking spray and bake for 20 minutes until chicken is cooked through. Serve with squeeze of lemon wedge overtop, if desired.
