Other storage rules to consider

Generally, an airtight container can be stored at room temperature as long as it is kept away from sunlight and hot spots, such as near the oven. However, donuts filled with jelly, cream, or dairy should be refrigerated to prevent mold growth. While storing regular donuts in the fridge can extend their freshness, it may also result in a chewier texture.
For longer-term storage, donuts can be frozen for up to three months without spoiling. Any type of donut can be frozen, but plain ones tend to freeze better than those with heavy frosting. Before enjoying your leftover donuts, it's wise to inspect them for edibility. If you notice any mold or smell something off, it's best to throw them away.
While it's nearly impossible to replicate the taste and texture of a freshly baked donut, microwaving a day-old donut for about twenty seconds can come close. Additionally, stale donuts can be a fantastic ingredient for other desserts, such as donut bread pudding or a donut ice cream sundae.
