Slice the chicken breasts into strips or bite-sized pieces.
In a shallow bowl, combine the cornstarch, flour, and seasoning blend. Coat the chicken evenly in the mixture.
In a separate bowl, whisk together the pancake mix, eggs, and water until smooth. Set aside.
Preheat the air fryer to 380°F (193°C) for 3 minutes.
Lightly spray the air fryer basket with oil. Place the chicken in a single layer and air fry at 380°F (193°C) for 10 to 12 minutes, flipping halfway through, until golden and cooked through.
Remove the chicken and keep warm.
Pour the pancake batter into a lightly greased air fryer-safe pan or silicone mold that fits inside your air fryer basket.
Air fry at 320°F (160°C) for 8 to 10 minutes, or until the center is set and a toothpick inserted in the middle comes out clean.
Carefully remove the waffle-style pancake from the pan and cut into serving portions.
