Mix flour, baking powder, and salt.
2 c. all-purpose flour, 2 1/2 tsp. baking powder, 1/2 tsp. salt
Cut in the butter, using a pastry blender, until particles are about the size of small peas.
2/3 c. butter or shortening
Add the milk and press together gently, working the dough only enough to hold it together. Do not overmix. If the dough is too dry and doesn't want to hang together, add more milk until it becomes cohesive.
3/4 c. milk
Sprinkle your clean countertop with flour and roll out the dough as you would for a pie. But you want to roll it out into about a 17 x 12 1/2" rectangle instead of a circle.
Cut the rectangle into six equal-sized squares. Place a whole apple onto each square, and gather the dough up over the apple. Moisten the top edges with a bit of cold water and fasten them securely at the top of the apple. You will want to try to create a seal. Although some of mine will crack open a bit sometimes when baking, and it's not a big deal.
Spread the six dumplings into a greased 9 x 13" baking dish.
