Preheat the oven to 450 degrees

In a food processor, combine flour, baking powder, salt and butter.  Pulse until the mixture resembles a coarse meal.

Add the buttermilk and process until combined... about 15 pulses in the food processor.  The mixture should be lumpy and thick.  Do not overmix

Scoop the biscuits using tablespoon or 1/4 cup measuring spoon. I like to put 2 tablespoons of biscuit mix in each.  Press down slightly on the biscuits in the pan so that they have smooth tops.

Brush with buttermilk and bake in the heated oven for 18 to 22 minutes until the biscuits are golden brown on top.
