Expiration & Storage Tips
When does cake mix expire?
Unopened cake mixes can last anywhere from 9 months to a year past the 'best by' date printed on the package, thanks to their dry nature and typically airtight packaging. Once the package is opened, if stored correctly, it can generally still be used for another 4 to 5 months. Freezing the dry mix isn't typically necessary or recommended due to the long shelf-life of the product.
How do you tell if cake mix is bad?
When cake mix has gone bad, it might develop an off smell, changes in color, or the texture may become clumpy. If the mix has been exposed to moisture, it can begin to develop mold. Remember, if you are ever in doubt, it's better to be safe and throw it out!
Tips for storing cake mix to extend shelf life
• Keep the cake mix in a cool, dark and dry area, such as a pantry.
• Once opened, consider transferring the mix to an airtight container or resealable bag to prevent exposure to air and moisture.
• Label containers with the date you opened the mix and try to use it within four to five months.
• Don't store your cake mix, or other similar dry ingredients, near strong smelling foods or cleaning products to avoid absorbing those odors.
