Preheat your oven to 450°F (232°C).

In a large mixing bowl, whisk together the all-purpose flour, baking powder, and salt until well mixed.

Add the chilled, cubed unsalted butter to the bowl. Using a pastry cutter or your fingertips, work the butter into the flour mixture until it resembles coarse crumbs.

Gradually stir in the milk until the dough starts to come together. Be careful not to overmix.

Turn the dough out onto a floured surface. Gently knead the dough 4-5 times until it is smooth. Roll it out to about 1-inch thick.

Use a biscuit cutter or a glass to cut out round biscuits from the dough. Place them on a baking sheet lined with parchment paper.

Bake in the preheated oven for about 12-15 minutes, or until the tops are golden brown.

Remove from the oven, let them cool slightly, and serve warm.
