In the work bowl of a food processor, pulse flour, sugar, and salt until combined. Add cold butter, and pulse until mixture is crumbly. With processor running, add cold buttermilk in a slow, steady stream until a dough forms.
Divide dough in half, and shape each half into a disk. Wrap tightly in plastic wrap, and refrigerate for at least 30 minutes or overnight.
