Combine flour, sugar, and salt in the bowl of a food processor. Pulse 4-5 times. Add the butter and pulse until pea-sized crumbs form.
Slowly stream in the ice water and process the dough until a ball forms, approximately 30 seconds.
Turn the dough out onto a lightly floured work surface.
Knead the dough until it is completely smooth and the butter is incorporated.
Divide the dough into two equal pieces and form into a disk.
Wrap each disk in plastic and refrigerate for 1 hour or up to 3 days.
