sheets in staggered rows and separating them by 1-1/2". The ends of each finger should be fatter than the center, like a dumbbell. Bake, 1 sheet at a time, until the cookies are lightly browned around the edges but still pale in the center, about 6 to 10 minutes. Slide the cookies onto a wire rack using a metal spatula and let cook to room temperature. Store in a covered airtight cookie jar or tin for up to 1 week.
