Even if your whipped cream is stored and stabilized correctly, it — like all dairy products — will eventually spoil. As such, it is important to keep an eye out for signs that the cream has spoiled in order to avoid consuming pathogens that could make you sick. Keep an eye out for signs of expiration to determine if you should throw out your whipped cream. If the cream shows significant changes in color or texture, such as a yellowish hue or lumpiness, or if it has a sour smell, it is best to dispose of it rather than eating it.
If you need to further extend the shelf life of your whipped cream, it is possible to make it last for up to several months by freezing it. Simply place the whipped cream into an airtight container, such as a sealable plastic bag, and then stick it into the freezer. You can then thaw the whipped cream when you are ready to use it, and it should retain the majority of its flavor and texture.
