01 - Preheat oven to 375°F and lightly grease a 9x13-inch baking dish with cooking spray or butter.
02 - In a mixing bowl, combine cream cheese, sour cream, milk, garlic powder, onion powder, salt, and pepper. Beat until smooth and creamy.
03 - Add shredded chicken, cheddar cheese, and green onions to the cream mixture. Stir until evenly distributed throughout.
04 - Unroll crescent dough and separate into 8 triangles. Place a generous spoonful of chicken mixture on the wide end of each triangle.
05 - Roll each triangle from wide end to tip, enclosing the filling completely. Pinch seams gently to seal.
06 - Place filled crescents in prepared baking dish, arranging them evenly. Spoon any remaining chicken mixture around the rolls.
07 - Sprinkle mozzarella cheese evenly over the crescents and exposed filling.
08 - Bake for 25-30 minutes until crescents are golden brown, cheese is melted, and filling is bubbly around edges.
09 - Allow dish to rest for 5 minutes before serving to let filling set and cool slightly.
