How to Make It
Preheat oven to 375°F with racks in upper and lower thirds. Stir together all ingredients in a medium bowl until evenly combined. Divide dough into 22 balls, and place 2 inches apart on 2 parchment-lined baking sheets. Gently flatten cookies with a fork, making a criss-cross pattern. Bake, rotating sheet 180° and top to bottom just until tops are dry, 8 to 10 minutes. Transfer cookies to a wire rack, and cool completely, about 1 hour.
