You should keep foods out of the danger zone to prevent bacteria from forming on foods. Bacteria can form on foods in the danger zone after just an hour. The danger zone is under 145 degrees and over 45 degrees.

Does a box cake mix with icing spoil after three days?

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.


How long for buttercream to go hard?

The time required for buttercream to develop a firm crust depends on a number of factors, including the proportion of ingredients used, the temperature of the ingredients when combined, and the temperature and humidity of the room. Generally, if you want to be certain the buttercream crusts over fully, you should leave the cake uncovered overnight. It will crust more quickly in the refrigerator, but will still take several hours. > It would take several days for buttercream frosting to become completely hard all the way through. Even then it will be quite soft. Hard icing decorations are not made out of buttercream but out of royal icing.

The same lengh of time as the use-by date on the cream cheese, provided the frosting is kept in the refridgerator.

Can you leave a cake frosted with cream cheese frosting at room temperature?

If you want my personal thought, which may not be correct, I think maybe in the next day it will ROT and stink. If it's a type of cheese, yeah, it will stink and rot. Cream cheese should not sit out at room temperature for more than 2 hours. Less time is better.
