Preheat oven to 450° F. In a medium bowl, combine the flour, salt, and baking powder. Whisk thoroughly to combine.
Cube the butter and stir into the dry ingredients. Using a pastry cutter, two knives, a food processor, or your hands, cut the butter into the flour until it resembles course crumbs.
Pour the milk into the bowl and stir to combine. When it comes together into a dough, knead it once or twice on a floured surface. Roll dough out until it's about a ½ inch thick. Using a biscuit cutter or a drinking glass, cut out biscuit rounds.
Place biscuits on an ungreased or silicone lined baking sheet and bake for 10 to 12 minutes.
