If it is a "cold ice cream cake", it will be kept at 18 to 22 degrees for one day, and it will definitely melt after more than one day.
The cake itself should be eaten on the same day, and the taste will be much worse the next day. The cream on the next day will be sour (there will be bacteria if it has been eaten), and the moisture will be reduced and it will be easy to dry. Most people will throw it away the next day. The shelf life is very short.
Extended data:
1, ice cream cakes are usually kept in the freezer, and they should be eaten as soon as possible, and the time should not exceed 1 day, otherwise they will all melt away and go bad.
2. In addition, because the cake is thin, it is easy to be damaged when it is taken out, so do this: first spray oil on the baking tray, then spread a layer of wax paper, and then spray another layer of oil on the wax paper. After baking, take out the paper directly and tear it off, so it won't be damaged. This method is also very suitable for making cake rolls.
