Preheat your oven to 400°F (205°C).
Lightly grease a baking dish with cooking spray or oil.
Add ⅓ cup honey, 2 tablespoons soy sauce, and a small splash of vinegar directly into the baking dish.
Sprinkle in garlic powder, salt, and black pepper, then stir everything together until well combined to form a sticky glaze.
Place the thin-sliced chicken breasts into the dish.
Flip the chicken a few times so that both sides are fully coated in the glaze.
Season the chicken however you like.
Scatter small pieces of butter evenly over the chicken.
Bake uncovered for 20–25 minutes, or until the chicken is cooked through and reaches 165°F internal temperature.
Remove from the oven and let rest for 2–3 minutes before serving.
