01 - Preheat the oven to 375°F. Lightly grease a 9x13-inch baking dish with cooking spray or butter.
02 - In a mixing bowl, combine the cream cheese, sour cream, milk, garlic powder, onion powder, salt, and pepper. Beat until smooth and well blended.
03 - Add the shredded chicken, cheddar cheese, and green onions to the bowl. Mix thoroughly until all ingredients are evenly distributed.
04 - Unroll the crescent dough and separate into 8 triangles. Place a heaping spoonful of the chicken mixture onto the wide end of each triangle. Roll up from the wide end to the point, enclosing the filling completely.
05 - Place the filled crescents in the prepared baking dish, arranging them in a single layer with the point side down.
06 - Pour any remaining chicken mixture around the rolls in the dish, ensuring even distribution.
07 - Sprinkle mozzarella cheese evenly over the top of the crescents and filling mixture, if using.
08 - Bake for 25 to 30 minutes, or until the crescents are golden brown and the filling is hot and bubbly.
09 - Remove from oven and let rest for 5 minutes before serving to allow the filling to set slightly.
