Is it Safe to Use Expired Pancake Mix?

If you want to make pancake mix last, you might want to use some past its expiration date. Search the package and look for any dates stamped on it.

But is it safe? Yes and no.

  • If you don’t seal the product tightly, mites could get in.
  • If it’s damp outside, the box can begin growing mold.

Will Expired Pancake Mixes Make Me Sick?

If you have an allergic reaction to mold or the powder was contaminated somehow, old pancake mix won’t make you sick. (*)

Should you get a stomachache after eating pancakes that came from a box mix, you may have some type of food intolerance.

A Trial Run

Two pancakes will reveal all you need to know.

  • Add more leavening
  • Add more flavor (like vanilla), or
  • Invest in a new box of mix.

How to Store a Package of Pancake Mix

The way you store your package directly impacts the taste and quality of your pancakes, as well as whether or not the pancake mix spoils more quickly than expected.

Storage Tips:

Commercial package is an ideal candidate for your kitchen pantry. The flour component itself has a 6-8 month shelf life in a sealed container. (*)

Freeze it!

If you’re getting to the end of a box’s expiration date, consider making up what’s left and put it in your freezer.

Just make sure the powder has a tight seal. Dampness and pancake mix before you intend to make it can become the culprit for mold buildup.

In batter form, your pancake mix can last up to 3 months in the freezer (32 degrees F). (*)

How To Tell Pancake Mix Is Bad?

In some ways, a pancake mix package is like cake mixes or bags of flour. There’s a tendency to think they will remain good nearly indefinitely.

Worse, dry components are sneaky. It’s not always easy to spot problems.

If you’re wondering if the mix is safe to eat, here are some signs for which to watch:

  • Obvious mold
  • Mites (these aren’t easy to see, so look close!)
  • Oxidized, stale taste. The powder isn’t necessarily bad, but it isn’t pleasant either.
  • A weird odor you’ve never encountered before
  • Wet clumps

As always, when in doubt, throw it out. (*)


Does quality suffer as pancake mix ages?

The long life of pancake mix doesn’t mean it’s perfect. Over time, quality absolutely decreases even when stored and sealed carefully.
When the shelf life of pancake mix passes, the main thing that suffers is the leavening (baking powder or baking soda), and who really wants “flat” pancakes?

How long does pancake mix last past the best-by date?

From a manufacturer’s point of view, the best by date has to do with quality. Most dry products like pancake mix can easily outlast those dates by half a year. (*)
So, in our opinion, the best-by date is not a solid measure of whether or not your pancake mix is bad. In fact, the package may retain its quality and flavor for months when properly stored.
