about a week...but look at the mixture and make sure there isn't any bacteria or clumps
This is an ingredient that is added into boxed cake. It is meant to help keep the cake sticking together even after being in the box for awhile.
It means that the contents will still be fresh until the last date printed on the box. If a month is given, the contents will be fresh until the end of the month.
Each recipe can vary, but box cakes usually require one or two eggs, the boxed cake mix, some water, and some oil.
You will need about 1.5 boxed cake mixes, so it is best to prepare 2. Some tall cake pans will require 2 full cake mixes, too.
To make a box cake in the microwave, prepare the cake batter according to the instructions on the box. Then, pour the batter into a microwave-safe dish and cook it in the microwave on high for the recommended time. Check the cake for doneness by inserting a toothpick into the center if it comes out clean, the cake is ready. Let it cool before serving.
If it is still in the box (just the mix), then it can last for a week or two after the expiration date on the box. If the cake has already been prepared and baked, then it can last for a week or so if stored properly.
The past tense is boxed.
It is not clear whether the question refers to a box cake mix still in the package, or a cake made from a boxed mix, that has been frosted. In that case, the answer depends on the type of frosting. A cake prepared from a mix, frosted with buttercream type icing should be fine for three days, and longer, as long as it is kept covered and cool. It does not need refrigerated unless the room temperature is quite warm.
Check the expiry date.
