How lengthy Does Cake Mix Last

Cake mixes come v a shelf life of around 6 months to a year, however you deserve to safely usage them because that months (or also years) previous the best-by day on the label. Opened the package, suspect you’re walk to store the leftovers properly, doesn’t shorten the period.

The best-by day on the brand isn’t an expiration date. It’s an estimate of how long the cake base will certainly retain peak quality.

Here’s just how Duncan Hines puts the in their FAQ (DH):

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

Cake mix: day on label
Now the you understand you can use one expired cake mix, the noticeable question pops up.

How long is cake mix great after the “expiration” date?

4 to 6 month after the best-by or best-before day on the label is a pretty safe bet, but your cakes must turn out good for lot longer. All you require is to include some baking powder or baking soda to make up for the raising agent that lost its potency.

Let’s talk around that.

Using Expired Cake Mix

The dry mix usually contains a leavening agent choose baking flour or baking soda. These room responsible for raising the volume of the dough.

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

The fix?

You guessed the – adding more baking powder or soda back in.

Here’s how:

Check if your mix uses baking powder or baking soda (sodium bicarbonate). In many cases, it’s the former.Add the baking soda or powder to her dry mix. If her mix is 6+ months after that date, usage one-fourth the the amount. If it’s an ext than a year, use half. 2 years or more? usage three-fourths or also the totality amount (if it’s “expired” for like three years). The older the mix, the more of the elevating agent us add.

I cannot guarantee this trick will work precisely as you would choose it to due to the fact that every cake mix is contempt different. However going v it should aid a fair bit.


If your cake mix is more 보다 4 – 5 months previous its date, don’t usage it for a baking task that have to turn the end perfectly, e.g., a birthday cake or a rhubarb cake you do only once or double a year. Instead, use it in a recipe you wanted to check out throughout the weekend, so if points go south, it’s not a huge deal.

Now, if the mix is old, the worse that deserve to realistically take place is a bunch that cupcakes or muffins the are level (if you didn’t include the elevating agent) or taste no as an excellent as they provided to.
