The most common mistake is overbaking. Pull the cookies when the centers still look slightly underdone — they will continue to set on the hot pan. For the best texture, use dark brown sugar and old-fashioned rolled oats. If you want to bake from frozen, add 2 minutes to the bake time. Stored in an airtight container, these stay soft for up to 5 days.
