In a large bowl, sift together dry ingredients. Cut in butter until mixture resembles coarse oatmeal. Make a well in the center of the dry mixture and pour in the milk. Stir until dough begins to pull together then turn out onto a lightly floured surface.
Press dough together and then roll out until 3/4 inch thick. Cut into 2 inch round biscuits and place on an ungreased baking sheet.
Bake in preheated oven for 10 minutes, or until golden.
