How To Tell if Your Baking Powder Has Expired

Image placeholder title

Baking powder is a key ingredient in many recipes, from cookies to cakes to muffins. But because we only use a scant amount at a time, it can be hard to know how long that tin has been opened in the cupboard, and whether it's still ready to give baked goods the lift they need. Use our handy guide to tell if your baking powder is expired, and avoid common baking problems.

Testing Baking Powder

Testing baking powder for activeness is actually fairly simple. Bring a cup of water to a boil. Put a teaspoon of the baking powder into a large bowl, and pour the boiling water over it. Why use a big bowl? Because if your baking powder is still good, the water will bubble violently, expanding about twice its volume.

A Quick Baking Powder Replacement
