Mix the dry ingredients. Pulse all-purpose flour, salt, and sugar together in a food processor.
Pulse in half of the butter. Scatter half of the butter cubes over the flour mixture and pulse until the butter is cut up into pieces no larger than a pea.
Add ice water and the remaining butter. Drizzle in ice water and scatter the remaining butter cubes into the food processor. Pulse until very small lumps form, and it holds together when squeezed.
Form the dough into discs and chill. Dump the mixture out onto a work surface and gather the lumps together and form into 2 portions. Shape each into a disk, wrap in plastic wrap, and refrigerate for at least 1 hour before rolling out.
