Does baking powder have a long shelf life?

Baking powder generally lasts 6 months to a year after opening, but can be good longer if stored properly; unopened, it can last up to 18-24 months, though freshness declines over time, so test it with hot water—if it fizzes vigorously, it's still good, otherwise, replace it for light, fluffy baked goods.

Can you revive old baking powder?

Executive chef Leslie Chartier says that yes, you can use expired baking powder. While it's not harmful to use after it's expired, it may not make your baked goods rise.
