Is it necessary to keep peanut butter fudge in the refrigerator?

Yes, peanut butter fudge should be refrigerated to maintain its texture and freshness. Since fudge is a high-sugar, high-fat dessert, it can spoil easily if left at room temperature for too long. When stored in the refrigerator, the fudge will last for several days or up to a week. To avoid moisture and air from seeping in, it’s recommended to store the fudge in an airtight container or securely wrapped with plastic wrap. Allow the fudge to rest at room temperature for a few minutes before serving if you desire a softer texture. It’s important to note that if the fudge has any additional perishable ingredients like milk or cream, it should be refrigerated even more promptly to avoid spoilage.

What is the shelf life of fudge?

The shelf life of fudge depends on the type of fudge, the ingredients used, and how it is stored. Generally, fudge can last for up to two to three weeks if stored properly in an airtight container at room temperature. However, if the fudge contains perishable ingredients such as cream or milk, it should be refrigerated and consumed within a week. It’s important to note that fudge may lose its freshness and texture over time, and may become dry or hard if stored for too long. To keep fudge fresh for longer, store it in a cool, dry place and avoid exposure to direct sunlight, heat, or humidity.
