Place bacon in a large skillet over medium-high heat to cook. Remove bacon from the pan and reserve the grease.
Stir together flour and baking powder in a medium bowl. Stir in potatoes to make a sticky dough.
Bring a large pot of water to a boil and add salt. Shape potato mixture into 6 or 7 dumplings, or your desired size. Drop carefully into the boiling water. Simmer for 45 to 60 minutes. Remove to a platter with a slotted spoon.
Serve with bacon grease brushed over the top and crumbled bacon.
