Preheat the oven to 450°F (230°C).

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

Add the cold, cubed butter to the flour mixture. Use a pastry cutter or fork to blend until resembling coarse crumbs.

Pour in the milk and stir gently until just combined.

Lightly flour your work surface and turn out the dough.

Roll the dough to about 1 inch thick.

Use a biscuit cutter to cut out rounds, pressing straight down.

Place the biscuits on a baking sheet and bake for 12-15 minutes until golden brown.
