Preheat your oven to 450°F (230°C).
In a large bowl, combine flour, baking powder, and salt.
Add the cold, cubed butter to the flour mixture.
Using a pastry cutter, mix until the mixture resembles coarse crumbs.
Pour in the milk and stir until just combined.
Turn the dough onto a floured surface and knead gently.
Roll out the dough to about 1-inch thickness.
Use a biscuit cutter to cut out biscuits.
Place the biscuits on a baking sheet lined with parchment paper.
Bake for 12-15 minutes or until golden brown.
