In this article we will learn everything about Cake Mix, including the shelf life of Cake Mix, how to store Cake Mix and when it expires.

Let’s see more about all this!

How Long Does Cake Mix Last

How long is the shelf life of Cake Mix? Cake Mix has a shelf life of up to 6 months and can even last a year. However, after the expiration date it can still last for months and you can use it safely for months or even a year.

If you have opened the packaging, you should store it properly so you can extend its shelf life to the maximum.

The best-by date stated on the label is the expiration time, this is an estimate of how much Cake Mix can maintain its quality. So, after the expiration date, you can still eat it safely.

Now that you know that expired cake mix can still be used, the question that arises is:

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

Cake mix is still good after 4 to 6 months. The best-by or best-before date is listed and it is still considered safe to use. However, its quality and potential are decreasing.

Using Expired Cake Mix

Usually, dry cake mixes contain leavening ingredients such as baking powder or baking soda, and these are ingredients that can increase the volume of the dough.

However, baking soda and baking powder, over time, they will lose their potency. So, even if the dough is 5 years old, it is still safe to use, and most likely the cake will just be flat.

How do I fix it, whether by adding more baking soda or baking powder?

Let’s see how to do it below!

Here’s how:

Try checking whether your mix uses baking soda or baking powder.

Then figure out how much base you need, and find a cake recipe that is similar in texture and size to what you want to bake with your mix. Use the same developer.

Also see how many ingredients are needed in the recipe. Mix this DIY cake with one tablespoon of baking powder for every 4 cups of mix.

Add baking soda or baking powder to your dry mix. If your mix is more than 6 months past the expiration date, then use 1/4 of that amount. Also when your mix has been expired for more than a year, then use 1/2 of the amount. If it is 2 years or more from the expiration date, then use it all. The longer the expiration date, the more you have to add.

This is a trick that some people have tried, we cannot guarantee that this trick will work for you too or that you will be successful using it. The reason is because every cake has a different dough, but using this trick can help you a little.


If your cake mix is more than 4-5 months out of date, then don’t use it for your cake making projects that require you to make a perfect cake. You can use the method above if the purpose of your cake mix is for you to eat together at home with your family.

For example, if you are making a birthday cake or rhubarb cake that you only make once a year, then don’t use a cake mix that has expired. But if you want to use cake mix in a test recipe or are learning to make cakes, then you can use one that has expired.
