#starch-retrogradation

We first have to answer the question: What actually causes cookies to go stale? Well, it's due to a chemical process called starch retrogradation; once baked goods leave the heat of the oven, the starch molecules recrystallize - a process that's expedited by exposure to air. The most logical solution, of course, is not to leave your cookies sitting out on a plate. But to preserve their texture even more, you may want to reach for that roll of paper towels.
