How long can I store a Duncan Hines cake mix?

Duncan Hines cake mixes can generally be stored for an extended period, often up to one year from the date of manufacture if kept in a cool, dry place. It is important to pay attention to the expiration date printed on the box. While cake mixes can still be used after this date, their quality may begin to decline, which could affect the texture and flavor of the final product. Proper storage is key to maintaining the mix's freshness, so it is advisable to keep the box tightly closed to avoid exposure to moisture and contaminants. If you notice any off odors, unusual discoloration, or changes in texture, it is wise to discard the mix. For specific guidelines regarding storage or any other concerns, one might find useful information on the official Duncan Hines website, where they provide detailed product information. Always trust your senses when determining the usability of a cake mix.
