Easy Baking Powder Drop Biscuits

Preheat an oven to 450 degrees F (230 degrees C).
Mix flour, baking powder, salt, and sugar in a bowl. Cut in the cold butter with a knife or pastry blender until the mixture resembles coarse crumbs. Add milk a little at a time, stirring lightly between additions.
Drop the batter by spoonfuls onto a cookie sheet, and bake for 12 to 15 minutes, until the tops are golden.
