1Whisk together AP flour and baking powder in a medium bowl.
2Add cold butter to dry ingredients and cut butter in with 2 forks or a pastry blender until a crumbly flour mixture is achieved.
3Pour milk into the flour mixture and stir together until well combined.
4Turn your dumpling dough out onto a countertop that has been generously dusted with flour. Sprinkle the top of your dumpling dough with flour before rolling out with a well-floured rolling pin. Roll dumpling dough out to a 1/4 inch thickness. If your dumpling dough is too sticky, add additional flour as needed to keep the dumpling dough from sticking to the countertop and rolling pin.
5Cut dumplings into 2-inch squares with a pizza cutter or sharp knife. Lightly dust the top of the cut dumplings with flour.
6Bring chicken broth to a boil. Once boiling, add shredded chicken to the chicken broth and stir.
7Reduce heat to medium and add dumplings, one at a time, to the pot, stirring occasionally to ensure the dumplings do not stick together.
8Allow dumplings to cook over medium heat for about 15-18 minutes. The broth thickens as the dumplings cook. To test a dumpling for doneness, take one out and taste it. It should not taste doughy once thoroughly cooked. Serve immediately!
