Remove one half of the chilled dough at a time. Use a 2-inch round cookie cutter to cut out 28 circles from each half, re-rolling scraps as needed. Place cookies on a parchment-lined baking sheet with minimal spacing. Bake at 350°F for eight minutes. Allow cookies to cool on the baking sheet for 5 minutes before transferring to a rack to cool completely.
