Pre-heat the oven to 450°F.
In a large mixing bowl, whisk together the flour, baking powder and salt.
Using a pastry cutter or your fingers, cut in the butter until the mixture resembles coarse sand.
Make a well in the center of the mixture and pour in the buttermilk.
Stir just until the dough comes together.
Turn the dough out onto a lightly floured surface and knead it gently a few times.
Pat the dough out into a 1-inch thick rectangle.
Using a 2-inch biscuit cutter, cut out as many biscuits as you can and place them on a baking sheet.
Gather the scraps and pat them out again, cutting out additional biscuits until all the dough has been used.
Place in the pre-heated oven and bake the biscuits for 12 to 15 minutes or until golden brown; serve warm.
