In a bowl combine the flour, sugar, salt and baking powder. Cut in the butter with a pastry knife until crumbly. Stir in the milk with a fork and stir until a soft dough forms. You may need to add more milk. Once it resembles dough, you can use your hands to mix it together, then turn out on a floured surface and pat or roll out to 3/4" thick and cut out rounds with a 2" cutter.
