Moldy chocolate is a term used to describe chocolate that has shown signs of mold growth. Although rare, mold may form on chocolates if you expose them to too much moisture.

Why does chocolate get moldy?

The most common cause of moldy chocolate is improper storage. Mold spores are present in the atmosphere, but chocolate doesn’t contain enough moisture to support their growth.

When you leave your chocolate in a wet or humid environment, such as on your kitchen sink or in your bathroom, the moisture content of the chocolate will rapidly start to increase.

This allows the mold spores present in the atmosphere to contaminate your chocolate and thrive on it. Once this happens, your chocolate will start to change color and develop other signs of mold growth.
