If you’ve got some baking powder in your pantry that’s been sitting there for a while, you might be wondering if it’s still good to use. Will your baked goods still rise, or will they end up flat and dense? Let me explain everything.
Baking powder helps things rise when baking. It releases carbon dioxide when mixed with liquid and heat, which creates bubbles that make your cakes, muffins, and pancakes light and fluffy. Without it, your treats will come out heavy and dense.
When baking powder expires, it loses its effectiveness. It won’t work as well when mixed with your ingredients, and that means your cakes might turn out more like bricks or your cookies might be harder than usual. Using expired baking powder won’t hurt you, but it won’t give you that nice rise you’re expecting.
How to Test If Your Baking Powder is Still Good
To check if your baking powder is still good, you can do a simple test. Take a teaspoon of baking powder and mix it into a small amount of warm water. If it bubbles and fizzes right away, it’s still good to go. If there’s little or no reaction, it’s time to toss it.
How Long Does Baking Powder Last?
Baking powder typically lasts about 6 months to a year after opening. Always check the expiration date provided by the manufacturer and store it in a cool, dry place to keep it fresh. Baking powder is made up of an acid (usually cream of tartar), a base (often baking soda), and a starch (like cornstarch). These ingredients work together to create the chemical reaction that helps your baked goods rise. Over time, the reaction weakens, which is why expired baking powder won’t work as effectively.
Can You Use Expired Baking Powder?
You can use expired baking powder, but if you want your baked goods to rise the way they should, it’s best to use fresh baking powder. If you’re making something that really needs to be light and fluffy, like a cake or soufflé, don’t risk it.
By the way, you might be wondering about the difference between baking powder and bicarbonate of soda, also known as baking soda. While both help baked goods rise, they work differently. Baking powder contains both an acid and a base, while baking soda needs an acidic ingredient like vinegar or lemon juice to activate. Just to clarify, bicarbonate of soda is the same as baking soda. The name difference comes from where you are, baking soda is used in North America, while bicarbonate of soda is more common in the UK and other parts of the world.

Alternatives to Expired Baking Powder
If you’re in a pinch and don’t have fresh baking powder, you can make your own. For every teaspoon of baking powder needed, use 1/4 teaspoon of baking soda, 1/2 teaspoon of cream of tartar, and 1/4 teaspoon cornstarch (to prevent premature reaction). If you don’t have cream of tartar, you can use baking soda with an acid like lemon juice or vinegar. Just adjust the amounts so they match the recipe.
Is baking powder bad for you?
In normal baking amounts, there’s really no need to worry. It’s safe to use, but like anything, moderation is important. If you used a lot of baking powder, it could upset your stomach due to its alkaline properties disrupting your stomach acid balance, but that’s not something you’ll usually deal with when baking at home.
So, while using expired baking powder won’t harm you, it’s not going to give you the best results. It’s always better to use fresh baking powder or swap it out with something else if yours has expired. That way, you’ll get the perfect rise every time!
