Preheat your oven to 425°F.
In a large mixing bowl, whisk together the flour, baking powder, and salt until well combined.
Add the cold, cubed butter to the flour mixture.
Using a pastry cutter or your fingers, work the butter into the flour until the mixture resembles coarse crumbs.
Make a well in the center and pour in the milk.
Stir gently until just combined; do not overmix.
Turn the dough out onto a lightly floured surface and knead gently 3-4 times until it comes together.
Pat the dough into a 1-inch thick rectangle.
Cut out biscuits using a round cutter or a glass.
Place the biscuits on a baking sheet lined with parchment paper, ensuring they are touching for soft edges.
Bake for 12-15 minutes or until golden brown.
Remove from the oven and let cool slightly before serving.
