Place the flour, baking powder, salt, pepper, and dried parsley in a medium-sized bowl.
Add the butter pieces and cut them into the flour using two knives or a pastry cutter, until it resembles sand.
Add the milk and mix until a soft dough forms.
Flour the kitchen counter and place the dough on the counter.
Roll the dough into a ¼- inch thin sheet using a roller dusted with flour.
Cut the sheet into 2-inch squares using a knife or pizza cutter.
Make sure all surfaces are well covered or coated with flour because the squares might stick.
Place the chicken broth in a large pot and bring it to a soft boil.
Carefully pick up the squares of dough using a spatula dusted with flour and drop them into the boiling broth one by one.
Once all the dumplings are in the pot, carefully mix in the shredded chicken and cook until warmed through. Serve with freshly chopped parsley on top.
