So, what makes baking powder go off in the first place? It turns out, it's all about the chemical reaction that happens when you mix baking powder with liquid ingredients. It's like a tiny volcano eruption in your mixing bowl, except instead of lava, you get fluffy, delicious baked goods.
But, when baking powder is exposed to moisture, heat, or light, the chemical reaction can start to happen prematurely, making it less effective. That's why it's essential to store baking powder in a cool, dry place, like a pantry or cupboard. Don't go storing it in your basement or attic, unless you want to end up with a batch of flat, sad baked goods.
Now, you might be wondering, how can you tell if your baking powder has gone off? Well, there's a simple test - just mix 1 teaspoon of baking powder with 1/2 cup of hot water. If it fizzes and bubbles, it's still good to go. But, if it just sits there, looking all flat and boring, it's time to get a new can.

Another way to check is to look for the expiration date on the can. Most baking powder cans have a best by date, which is usually about 6 months from the date of manufacture. But, even if it's past the expiration date, it might still be usable - just do the fizz test to be sure.
