How long does an unopened package of cocoa powder last at room temperature? When properly stored and kept free from contaminants, an unopened package of unsweetened cocoa powder has an indefinite shelf life.
Is unopened cocoa powder safe to use after the "expiration" date on the package? Yes, provided it is properly stored and the package is undamaged - commercially packaged unsweetened cocoa powder will typically carry a " Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the unsweetened cocoa powder will remain at peak quality.
How can you tell if unsweetened cocoa powder is bad or spoiled? The best way is to smell and look at the cocoa mix: if unsweetened cocoa powder develops an off odor, flavor or appearance, or if insects appear, it should be discarded.
