How to Tell if Expired Baking Powder Is Still Viable

Baking powder is the leavening agent that gives the rise and fluffiness to your baked goods. Even when stored in a cool, dry place as directed, it is sensitive to the moisture and humidity in your home and will lose its effectiveness within 6 to 12 months. Test your baking powder to make sure it is still viable before using it in baking.

Things You'll Need

  • 1/2 cup hot water
  • 1/4 teaspoon baking powder
  • Spoon
  • Bowl

Instructions

  1. Pour 1/2 cup hot water into a bowl.

  2. Stir 1/4 teaspoon baking powder into the water.

  3. Observe the reaction. Active baking powder will bubble immediately. If there are just a few bubbles, it's losing its effectiveness. If there is no bubbling, the baking powder will not give your baked goods a rise.
