Using Expired Cake Mix?

December 11, 2008

Cake batter being whisked in a bowl.Can baking powder be added to freshen a cake mix past it's expiration date? During my late husband's bout with cancer, a lot of food items didn't get used since he didn't have an appetite.

How old is it? I have used them past the date before and they were fine. It is all dry ingredents so that is in your favor. I would probably try to use as it is.

So sorry to hear about your husband. I hope you are doing all right. Check to see if the mix has any type of milk product or a product that can spoil. If it does, then throw it out. It's not risk getting sick since certain foods can become rancid. Best to you and be well.

I've been guilty of letting cake mixes stay in my pantry too long and have always had good results by adding a little baking powder or baking soda, depending on which ingredient is listed on the box. If the box is out of date by only a few months, I don't add anything.


If it's out of date by a year, I add the baking powder or soda. Once when I did this to an out-of-date angel food cake mix, it ended up being the highest cake I've ever baked--and it tasted fine.

I would try it also with just the cake, and so sorry to hear about your husband. I lost mine nearly 2 yrs ago with cancer also, and lots of food left but it won't hurt to try it alone. If it doesn't work then you know. Also you could call the cake manufacturer.

Thanks, it has been hard, he was only 51. I called the manufacturer and they said it might not rise, so I thought maybe add baking powder? They said there was no danger in eating them, but they don't recommend using them past the expiration date.


This one is 18 mos. past expiration. I have thrown them out before, but everything has gone up and I'm trying to make my dollars stretch.

I have never had any problem using out of date mixes. A little baking powder will not hurt. I am glad it's not only me that does this.

Please don't take the chance. I used to think it was safe to use after the expiration date also; but, then I read a news article about a lady who poisoned her family using a cake mix that was past the expiration date. The flour itself had gone bad (but, it didn't have an odor and it was not discolored). Her entire family became very ill and her teenage son (who ate the most) almost died and did have permanent kidney damage. I forget exactly what they said it was (bacteria, fungus, virus, etc); but, it is something that is normally found in flour in very small amounts and is killed by baking.


However, over time the concentration increases and the byproducts of this "thing" are toxic and not destroyed by baking.

Ever since then, I always check the expiration date on anything that contains flour and if it is past the date, I get rid of it. It is not worth the risk.

I have used them to past the expiration date with no problem. There was a rumor circulating on the internet about pancake mix awhile back but it turned out to be false. I have used expired bread mixes too but replaced the yeast packet.
