Preheat the oven to 450°F (232°C).

Line a baking sheet with parchment paper or grease it lightly.

In a mixing bowl, whisk together the flour, baking powder, and salt.

Add the cold, cubed butter to the dry ingredients and cut in until the mixture resembles coarse crumbs.

Pour in the milk and stir gently until just combined.

Turn the dough onto a lightly floured surface, pat into a rectangle about 1 inch thick.

Fold the dough over itself a few times for extra flakiness.

Use a biscuit cutter or glass to cut out rounds from the dough.

Place the biscuits on the prepared baking sheet, leaving space between them.

Bake for 12-15 minutes or until golden brown.
