Preheat your oven to 450°F (230°C).
In a large mixing bowl, whisk together the flour, baking powder, and salt.
Using a pastry cutter or your fingers, cut the cold butter into the flour mixture until it resembles a coarse meal.
Pour in the buttermilk and mix until the dough comes together.
Turn the dough out onto a lightly floured surface and gently knead it a few times until it is smooth.
Pat the dough out to a thickness of about 1 inch. Using a biscuit cutter or a glass, cut the dough into circles and place them on a baking sheet.
Bake the biscuits for 10-12 minutes, or until they are golden brown on the outside.
Serve the biscuits warm, with butter and your choice of toppings. Enjoy!
