Preheat oven to 425 degrees.
Sift together flour, baking powder, and salt. Cut margarine in with a blending fork or dough blender until fat is the size of small peas. Add milk all at once. Stir until dough is all mixed and forms a ball.
Roll out on a lightly floured board to a thickness of about 1/4 inch. Cut with a 2 1/2-inch cutter or roll thicker and cut with a 2-inch cutter. Place 1 inch apart on a baking sheet. Bake 12 to 14 minutes.
