Cooling muffins for the right amount of time can help preserve their texture during storage. If you allow your muffins to cool too long, they'll begin to drown in their own steam, turning soggy. But if you try to extract your steaming, freshly baked muffins from a hot pan, they'll fall apart in your hand.
Cooling Time for Muffins
As a general rule, allow muffins -- even those with fresh fruit -- to cool inside the pan for a minimum of five minutes but no more than a half hour. Transfer the muffins from the pan to a baking rack and allow them to cool for an additional 10 to 15 minutes. At this point, you can enjoy the muffins or store them in your fridge or freezer in a resealable plastic container.
