Preheat oven to 400ºF (200ºC). Line a baking sheet with parchment paper. Set aside.
Pat the chicken dry with paper towels. Then, slice each chicken breast in half horizontally, making a total of 6 thinner cutlets.
Place the cutlets onto the lined baking sheet. Drizzle the chicken with olive oil, then rub it evenly over both sides.
In a small bowl, mix together the paprika, garlic powder, salt, and pepper. Sprinkle the seasoning mix evenly over both sides of the chicken.
Arrange the chicken in a single layer. Spoon 1 cup of Bang Bang sauce over the top of the chicken, spreading it out to cover each piece. Reserve the remaining sauce for serving.
Bake for 15–20 minutes, or until the chicken is cooked through and reaches an internal temperature of 165ºF (75ºC).
Remove from the oven and garnish with chopped parsley.
Serve over cooked rice and drizzle with the remaining Bang Bang sauce.
