What to Do With Expired Baking Powder: Don’t Toss It Just Yet!

Baking powder is a kitchen staple. It helps baked goods rise and become light and fluffy. But what happens when your baking powder reaches its expiration date? Don’t toss it out automatically! There are many ways to use expired baking powder that can save you money and reduce waste.

In this article, we’ll explore several creative ways to put expired baking powder to good use around the house. We’ll cover using it for cleaning, deodorizing, and even in some beauty treatments. So, the next time you find an expired container of baking powder in your pantry, think twice before throwing it away!

Can You Use Expired Baking Powder for Baking?

Let’s address the baking question first. Baking powder loses its leavening power over time. This means it won’t be as effective in making your cakes and cookies rise. If your baking powder is just a few months past its expiration date, it might still be okay to use. However, you may need to use slightly more than the recipe calls for.

Here’s a simple test to see if your baking powder is still active: Add ½ teaspoon of baking powder to ¼ cup of hot water. If it fizzes briskly, it’s still good. If there’s little to no fizz, it’s time to replace it.

However, if you’re particular about the texture and rise of your baked goods, it’s always best to use fresh baking powder.
