Preheat your oven to 425°F (220°C).
In a large bowl, whisk together the flour, baking powder, and salt.
Add the cold, cubed butter to the flour mixture.
Using a pastry cutter, blend the butter until the mixture resembles coarse crumbs.
Make a well in the center and pour in the milk.
Stir until just combined; do not overmix.
Turn the dough onto a lightly floured surface and knead gently.
Pat into a 1-inch thick circle and cut out biscuits with a round cutter.
Place biscuits on a baking sheet.
Bake for 12-15 minutes or until golden brown.
