In a large pot, combine the chicken, water, onion, carrots, celery, garlic, bay leaves, salt, and pepper.
Bring it to a boil over medium-high heat.
Reduce the heat and let it simmer for about 45 minutes, just until the chicken is cooked through and tender.
Remove the chicken from the pot and shred it into pieces.
While the chicken cools, prepare the dumplings.
In a bowl, mix flour, baking powder, milk, and melted butter until a dough forms.
Roll the dough out on a floured surface and cut it into small pieces.
Return the shredded chicken to the pot and bring the broth back to a simmer.
Drop the dumpling pieces into the broth one by one.
Allow them to cook for about 15 minutes, until they’re fluffy and cooked through.
Stir gently to combine everything well, ensuring the dumplings don’t stick to the pot.
Keep simmering until the mixture thickens slightly and the flavors meld nicely.
