In a medium bowl, whisk together the flour, baking powder, salt, garlic powder, and dried parsley.
In another bowl, whisk together the egg, milk, and melted butter until combined.
Add the wet ingredients to the dry ingredients and stir gently until just combined. The dough will be thick.
Add Dumplings to the Soup:
Using a spoon, drop spoonfuls of the dumpling dough into the simmering soup. Make sure not to overcrowd the pot.
Cover the pot with a lid and let the dumplings cook for 10-15 minutes without lifting the lid (they should puff up and become light and fluffy).
Serve:
Once the dumplings are cooked through, taste the soup and adjust the seasoning as needed.
Serve hot, garnished with chopped fresh parsley.
Enjoy your cozy Chicken and Dumpling Soup!
