How lengthy Does Cake Mix Last

Cake mixes come through a shelf life of about 6 months to a year, however you can safely use them for months (or even years) previous the best-by date on the label. Opened the package, suspect you’re going to keep the leftovers properly, doesn’t shorten the period.

The best-by date on the label isn’t one expiration date. It’s an estimate of just how long the cake base will certainly retain top quality.

Here’s just how Duncan Hines puts that in your FAQ (DH):

Once this time period has lapsed, we deserve to no much longer ensure that the all at once experience of the product will be what is needed.

Using Expired Cake Mix

The dried mix usually has a leavening agent favor baking flour or baking soda. These space responsible for raising the volume that the dough.

Unfortunately, both baking powder and baking soda lose potency over time. Therefore while a five-year-old mix could be perfectly safe to use, the cake will certainly most likely turn the end flat.

The fix?

You guessed it – adding much more baking flour or soda earlier in.

Here’s how:

Check if your mix offers baking flour or baking soda (sodium bicarbonate). In most cases, it’s the former.Add the baking soda or flour to your dry mix. If your mix is 6+ months after that date, usage one-fourth the the amount. If it’s more than a year, usage half. 2 years or more? usage three-fourths or also the totality amount (if it’s “expired” for prefer three years). The older the mix, the much more of the raising agent we add.

I cannot guarantee this trick will certainly work exactly as friend would like it to due to the fact that every cake mix is slightly different. But going v it should aid a same bit.


If your cake mix is more than 4 – 5 months past its date, don’t use it because that a baking task that should turn the end perfectly, e.g., a date of birth cake or a royal tree cake you do only when or double a year. Instead, usage it in a cooking recipes you want to test out during the weekend, for this reason if things go south, it’s not a large deal.

How To keep Cake Mix

Cake mix (or cake base, as some bakeries speak to it) doesn’t require much in terms of storage. All it needs is a cool and also dry place (DH).

And by cool I median that room temperature is good enough, as lengthy as that doesn’t sit near any type of sources of heat. It’s the same as with storing sprinkles.
