Place 1 cup flour into a food processor with the blade attachment. Sprinkle frozen butter cubes over flour.

Cover with remaining 1 cup flour, sugar, and salt. Pulse in short bursts until butter is broken down into small pieces, about 1 minute.

Drizzle in ice water. Pulse with longer pulses until mixture turns pale yellow and resembles bread crumbs, 10 to 12 seconds. Scrape down the sides with a spatula. Pulse 1 to 2 more times.

Transfer mixture onto a work surface and gather into a ball. Flatten slightly and wrap in plastic wrap. Chill in the refrigerator for at least 1 hour to overnight before rolling out.
