Baking powder is a leavening agent that helps baked goods rise, giving them a light and fluffy texture - who doesn't love a soft and fluffy cake? It's a mixture of baking soda and an acid (usually cream of tartar) that's designed to release gas when it comes into contact with liquid ingredients. This magic happens when you mix and bake, resulting in a delicious treat that's sure to put a smile on your face!
Now, back to the question at hand: how long is baking powder good for after opening? The answer is, it depends on how well you store it! If you keep it in a cool, dry place, away from direct sunlight and moisture, it can last for up to six months to a year. But, if you don't store it properly, its potency can decrease, and your baked goods might not turn out as expected.
