Generally, yes, although that might depend on what kind of cake it was.
It depends on the conditions. Usually, it will last for about 4 to 5 hours. If the weather or surrounding are very hot, humid, raining, next to a heater, under hot lights, or in direct sunlight, then it will last maybe only 2 or so hours.
I wouldn't store baked salmon in the frig. any longer than 3 days.
If it is kept cool it will last about three or four days.
about 3 or 4 days
If you leave a cake out on the counter for several days, it may become stale as it loses moisture and its texture changes. Depending on the ingredients and environmental conditions, it could also develop mold or spoil, especially if it contains perishable items like dairy or fruit. To maintain freshness, it's best to store the cake in an airtight container or refrigerate it if it won't be eaten within a day or two.
A sponge cake is soft and is suitable for flat cakes, also it has a shelf life of about two days. A Madeira cake is a firmer more textured cake, suitable for cake sculptures and has a shelf life of up to two weeks!
A sponge will last (at most) 5-7 days since it was baked. However icing with cream, cream cheese or raw/semi cooked eggs expire after 3 days in the fridge. So it's whichever expires first - the sponge or the icing that affects how long the cake will last.
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.
Within 3 days unless it is a fruit cake that has been preserved with alcohol. You can eat the cake after this time but unfortunately bacteria is already taking hold of the ingredients even if it is kept in the fridge. But outside of the 3 days the cake is drying out and is not enjoyable to eat.
Since there are no answers from the UK, then this is from Canada. A wedding cake should be stored in a cool place such as a spare fridge (but not for more than a couple of days) or a dark cool place like a cellar being sure that the cake is well covered. To preserve a soft cake if the icing is stiff to harder this will preserve the moisture in the cake.
Baked beans can last in a fridge for about five days. Baked beans can last in a freezer for about a year.
It doesn't have to be but it does need to be well covered and sealed or it will dry out. And if it wont be eaten within the next couple of days then yes refridgerate.....but yet, freeze it. It will taste almost as good as fresh baked if you microwave it for a few seconds after it has been sitting out, refriderated, or even frozen. depending on how long it will be before it is eaten, you can keep it in any one of these ways as long as it is properlly sealled.
