How Long Does Opened Dulce De Leche Last?
Once opened, dulce de leche can last for about two weeks if it is stored in an airtight container and refrigerated. It may still be safe to eat after that point, but the quality may have deteriorated, and it’s best to discard it if it has an off odor or taste. To extend the shelf life, you can also store dulce de leche in the freezer for up to six months.
