Preheat the oven to 450 degrees F (230 degrees C).

Mix Sriracha sauce, maple syrup, melted butter, garlic powder, salt, and pepper together in a small bowl.

Place chicken in a baking dish. Pour maple-Sriracha mixture over the chicken; turn and coat thoroughly.

Bake in the preheated oven until chicken is no longer pink in the center and juices run clear, 15 to 20 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
