In a bowl, mix together the flour, salt, and baking powder and cheese. Add part of the milk and stir. You may not need quite all of it, so judge as you go. Keep adding milk until you can bring the dough together. Turn it out onto a lightly floured surface. Knead the dough until all of the ingredients are incorporated, about 1 minute.
Using your fingers, press the dough out into a 1/2 inch thick circle or square. Cut the dough with a knife or use biscuit cutters to make the desired shapes. Place the biscuits on a cookie sheet. Brush the tops with melted butter and sprinkle the remaining cheese on top.
Bake about 15 minutes at 425 degrees.
