16. Cocoa Powder
Unopened cocoa powder can last for years without going bad. Its low moisture content means it’s not prone to mold or bacteria. Even after opening, it can still be good for a long time if stored properly. Keep it in a tightly sealed container in a cool, dark spot, and you’re good to go. It may lose some flavor after a few years, but it won’t spoil. Whether you’re baking brownies or making hot cocoa, having cocoa powder in your pantry is always a win.
