1.     Preheat oven to 400°F. Line a baking sheet with parchment paper and place a wire cooling rack on top. Spray the wire rack lightly with cooking spray to prevent sticking.

2.     Place the chicken breasts on a cutting board. Hold your knife parallel to the board and carefully slice each breast horizontally to create two thinner pieces.

3.     In a shallow dish, combine the flour, garlic salt, smoked paprika, onion powder, and pepper.

4.     In another shallow dish, whisk together the eggs and milk.

5.     Place the crushed cornflakes in a third shallow dish.

6.     Dredge each piece of chicken in the flour mixture, shaking off excess.

7.     Dip into the egg mixture, allowing excess to drip off.

8.     Press into the crushed cornflakes, ensuring both sides are well coated.

9.     Place the coated chicken pieces on the prepared wire rack over the baking sheet. Lightly spray the tops of the chicken with cooking spray.

10.  Bake for 20-25 minutes, or until chicken is golden brown and internal temperature reaches 165°F.

11.  Let rest for 5 minutes before serving.
