Start by cutting the chicken into evenly sized bite-sized pieces. This helps everything cook at the same rate and gives you consistent texture. Season lightly with salt and pepper before coating.
Dip each piece into cornstarch first, making sure it’s fully covered. Then coat it in beaten eggs so the crust sticks properly. This two-step coating creates a crisp outer layer once baked.
Preheat your oven and add oil to a baking dish, letting it heat up slightly. Place the coated chicken pieces in the dish and bake until lightly golden. Flip halfway through so both sides crisp up evenly.
In a bowl, whisk together buffalo sauce, brown sugar, apple cider vinegar, garlic powder, and red pepper flakes. The combination should taste sweet, spicy, and slightly tangy. Adjust heat or sweetness as needed.
Pour the sauce evenly over the partially baked chicken. Toss gently so every piece is coated. Return to the oven and bake until the sauce thickens and caramelizes beautifully.
