Common questions

How long does baking powder last in the pantry?

6–18 months from the date of purchase. 3–6 months after opening.

How can I tell if baking powder has gone bad?

Throw it out if it smells off, feels slimy or sticky, shows mold, or has changed color. Storage times assume it was handled safely and kept cold the whole time.
