Preheat the oven to 400 F.  Grease a baking sheet.

Combine the flour, baking powder and salt.  Cut in the butter or margarine until it has a fine crumb texture.

Stir in the milk with a fork to make a soft dough.  Knead 8 to 10 times, then roll out to the thickness of 1/2 inch.

Cut into rounds with a cookie or biscuit cutter.  Place on cookie sheet, and allow to rest for a few minutes.

Bake for 12 - 15 minutes.  Serve warm.
