Of course, the shelf life of cake mix will be shortened if the mix is not stored properly. Remember that most baking products usually have a best before date and not a use by date or expiration date. Because of this distinction, you may safely use "expired cake mix" for your baking needs after the best before date has lapsed according to the table above. See below for more details.

How to tell if Cake Mix is bad, rotten or spoiled?

Practicing proper hygiene and food safety techniques will help prevent foodborne illness.

When cake mix gets wet (by adding eggs, oil and water), the leavening agent contained in the mix gives off carbon dioxide which makes the cake rise. If a cake mix has gone bad the leavening agent will have expired and will not work as well as it should. This means that the resulting cake will not rise as high as it would have prior to the eat by date.

There are, of course, certain health risks associated with spoiled foods so always remember to practice food safety and enjoy your foods before their shelf life has expired!

How to store Cake Mix to extend its shelf life?

The best way to store cake mix is in its original unopened container in a cool dry pantry, at a constant temperature and away from heat sources. Cake mix will have a shorter shelf life in a humid environment or at high altitudes. Humid environments affect many different foods while high altitudes seem to especially pick on baked goods.

Some benefits of proper food storage include eating healthier, cutting food costs and helping the environment by avoiding waste.

How long is Cake Mix good for when prepared in a dish?

How long does cake mix last? That depends. How long do eggs last? In general, any dish lasts only as long as its quickest expiring ingredient.
