How lengthy Does Cake Mix Last

Cake mixes come v a shelf life of about 6 months to a year, yet you can safely usage them for months (or even years) past the best-by day on the label. Opened the package, assuming you’re going to save the leftovers properly, doesn’t shorten that period.

Here’s how:

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

I can not guarantee this trick will certainly work specifically as you would favor it to due to the fact that every cake mix is contempt different. But going with it should assist a same bit.


If your cake mix is more than 4 – 5 months past its date, don’t use it for a baking project that need to turn the end perfectly, e.g., a birthday cake or a rhubarb cake you make only when or twice a year. Instead, use it in a cooking recipes you wanted to check out throughout the weekend, therefore if things go south, it’s not a big deal.
