As tempting as eating a whole batch of fudge can seem, it's probably best to store some of it for later. Whether home-made or store-bought, fudge has a relatively long shelf life. With proper wrapping, it will last for weeks or even months.
Wrapping and Containers
Whether you're going to freeze your fudge, store it in a refrigerator or keep it at room temperature, the process begins with proper wrapping. Wrap each piece of fudge in waxed paper, then place the pieces in an airtight container such as a sealable plastic bag or box. The wax paper will prevent the fudge pieces from sticking together. Alternatively, you can wrap your fudge in plastic wrap or aluminum foil to protect it.
Room Temperature Storage
Although the exact length can vary, most fudge will keep for up to two weeks at room temperature. To extend its shelf life as much as possible, take some basic precautions. Keep the fudge in an area with a stable temperature. In particular, avoid direct sunlight. Fudge won't melt even in hot sunlight, but it will soften. If this happens, simply move the fudge to a cooler area and it will gradually become firm again.
Fudge freezes well; simply wrap and package the pieces, then place the container in your freezer. Your fudge should last for several months. When you're ready to bring your fudge out, take the wrapped pieces from the freezer and leave them at room temperature for two hours. A sheen of moisture may form on the surface of the fudge as it "sweats." Once the sheen is gone, the fudge is ready to eat.
Fudge in the Fridge
You can refrigerate fudge, although it's not the best storage method. Fudge will keep for several weeks in the refrigerator. However, fudge can dry out when refrigerated, losing some of its color and texture. Different fudges can vary in how they respond to refrigeration, so test your fudge to see how well it handles being cooled.
Allow refrigerated fudge to come back to room temperature before serving.
