In a mixing bowl, combine chicken wings, garlic powder, soy sauce, oyster sauce, and black pepper. Mix well then marinate for about 2 hours.
In a non-stick pan, put the marinated chicken wings then add Sprite. Cover then bring to a boil.
When it boils, lower the heat. Mix continuously until all the liquid has been absorbed by the chicken.
Remove from heat. Serve and enjoy your Sprite chicken wings!
