In a large pot, add the chicken breasts, chicken broth, salt, pepper, and garlic powder. Bring to a boil, then reduce the heat and simmer for about 20-25 minutes until the chicken is cooked through and tender. Remove chicken, shred it into bite-sized pieces, and set it aside. Keep the broth for later.
In a mixing bowl, combine flour, baking powder, and salt. Stir in milk and melted butter to form a soft, sticky dough. Avoid overmixing to keep the dumplings tender.
Dust a clean surface with flour. Roll the dough out to about 1/4-inch thickness, then cut into 1-inch squares. Set aside the dumpling pieces for cooking.
Bring the chicken broth back to a gentle boil. Drop the dumplings into the pot one at a time, stirring gently to prevent sticking. Cover and let them simmer for 10-15 minutes until the dumplings are cooked and fluffy.
Return the shredded chicken to the pot with the dumplings, stirring to combine. Simmer for another 5-7 minutes, letting the flavors meld together. Taste and adjust seasoning if needed.
Serve the chicken and dumplings warm. Enjoy the comfort of this Cracker Barrel favorite from the comfort of home!
