Fudge is considered candy, and candies have a high percentage of sugar and very low moisture, which means they do not spoil very fast. If you make and store it properly, you can use it anytime you need to make or bring a treat. Fudge is a perfect treat to make in large batches, just for gifting. It will last several weeks in the refrigerator tucked in an airtight container and about two weeks at room temperature. Ensure that it is not exposed to the environment and stays inside a container so it doesn't dry out. Getting dry is one of the reasons we usually throw the fudge away.
