Step 1

Combine the ice water and vinegar in a liquid measuring cup and set aside in the refrigerator. In the bowl of a stand mixer fitted with a paddle attachment, combine the flour, sugar, and salt. Mix on low speed until combined.

Step 2

Dice the cold butter into 1-tablespoon pieces. Add the butter to the mixer bowl and turn the mixer on low (cover the bowl with a towel if flour starts to spill out). Let the paddle cut the butter into the flour for about 30 seconds. There should still be large chunks of butter visible in the flour, with most of them the size of a walnut.

Step 3

With the mixer running, slowly stream half of the chilled water mixture into the dough. Mix until most of the dough comes together around the paddle, adding more water as needed, and then immediately shut off the mixer to avoid overworking the dough. Remove the dough from the mixer bowl and transfer it to a work surface. The dough should hold together easily when handled. Quickly shape the dough into a 1-inch-thick rectangle and wrap tightly in plastic wrap.

Step 4

Transfer the dough to the refrigerator and let it rest for at least 2 hours. If your kitchen is warm, you may want to let it rest longer to fully chill.

Step 5

Unwrap the dough and place it on a lightly floured work surface. Use a rolling pin to roll the dough, dusting with flour if necessary, into a 16-by-10-inch rectangle. Brush off any excess flour from the surface of the dough with a dry pastry brush.

Step 6

Fold the dough in half from the long side, forming a long, skinny rectangle. Then, fold one of the short sides over by about ⅓. Repeat folding over the opposite short side to form a thick, mostly square, layered piece of dough. Please see the step-by-step photos above or the video for a visual tutorial, if needed.

Step 7

Roll out the dough into a rectangle about 8 inches in length. Cut the dough in half to form two pieces of pie dough. If desired, the dough can be shaped into a circle at this point, or left as a square. Wrap each piece tightly in plastic wrap and let the dough chill for at least 30 minutes or up to 2 days. It is easiest to roll out the dough if it has chilled and rested overnight.

Step 8

When ready to use, roll out each piece of pie dough to a thickness of about ¼-inch and use as desired or directed in a recipe. See the notes in the post above for more information on how to store, freeze, use, and bake with this flaky pie dough!
