I have a hard time keeping my home-baked cookies from getting soft. I stack them in an airtight container, but they tend to stick together. I tried using plastic wrap between the stacks, but that makes them really soft. I have even more trouble with drop cookies. Can you help? —M.M., Longview, Texas
For crisp cookies, the general rule is to store them in a container with a loose-fitting cover. If you prefer soft cake-like cookies, store in a container with a tight-fitting cover. However, if the weather is humid, you should store crisp cookies in a container with a tight-fitting cover. Using waxed paper between the layers should keep them separate and from sticking together. If you are currently using plastic wrap, it may be that it does not allow enough air to circulate, which is why the cookies are sticking together.
Remember to always cool cookies completely before storing them. Warm cookies stored in a sealed container can cause an entire batch to soften from the steam they create. And don’t mix soft and crisp cookies in the same container. The moisture from the soft cookies will cause the crisp cookies to soften. Try keeping all of these things in mind the next time you store a batch. If your crisp cookies still become soft, place them on a baking sheet and warm them at 300° for 3-5 minutes.
