In a stockpot or Dutch oven, combine chicken broth, celery, onion, and chicken breasts. Bring to a boil, then reduce heat and simmer, partially covered, for about 15 minutes, until chicken is cooked through.

While chicken cooks, whisk together flour, baking powder, and salt in a medium mixing bowl. Stir in milk just until combined into a shaggy dough.

Turn dough out onto a floured surface and roll to about 1/4 inch thickness. Use a pizza cutter to cut the dough into strips or squares about 1 to 2 inches in size.
04 -
Once chicken is cooked through, remove to a cutting board. Remove and discard onion chunk and celery pieces from broth.

Add dough strips to the simmering broth and cook for about 20-30 minutes, stirring occasionally, allowing dumplings to cook and broth to thicken to a gravy-like consistency.

While dumplings simmer, shred or chop chicken and return to the pot. Season with salt and pepper to taste, then serve warm.
