Does freezing cocoa powder keep it fresher longer?

No, freezing cocoa powder does not keep it fresher longer. Cocoa powder is a dry ingredient that does not require freezing to maintain its freshness. In fact, freezing and thawing cocoa powder can introduce moisture and cause the cocoa powder to clump or lose its flavor. To keep cocoa powder fresh, store it in a cool, dry place, such as a pantry or cupboard.
