Gather ingredients and equipment.
Whisk flour, flour, sugar, and salt in large mixing bowl. Then, add butter and rub in with fingertips until small pea-size clumps form.
Add 5 tablespoons of ice water; mix lightly with fork until dough holds together when small pieces are pressed between fingertips, adding more water by teaspoons if dough is dry.
Gather dough together; divide into two pieces. Form each piece into ball, then wrap in plastic. Refrigerate for at least 30 minutes. Keep chilled. Let dough soften slightly before rolling out.
