Preheat the oven to 425°F (220°C).

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

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

Pour in the milk and stir gently until just combined.

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

Using a biscuit cutter, cut out rounds of dough and place them on a baking sheet lined with parchment paper.

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

Remove from the oven and let cool slightly before serving.
