Prepare the chicken by shredding it into bite-sized pieces and set aside.
In a large pot, combine shredded chicken, cream of chicken soup, chicken broth, and 1 cup of milk. Stir well and heat over medium heat for 5-7 minutes.
In a separate bowl, mix Bisquick, 1/2 cup milk, garlic powder, onion powder, salt, and black pepper until just combined to create the dumpling dough.
Drop spoonfuls of dumpling batter onto the chicken mixture, cover, and simmer on low heat for 15-20 minutes without lifting the lid.
Let the dish sit for a few minutes after cooking, garnish with parsley, and serve.
