Baking Powder (Cake flour)

Baking powder is a key ingredient in many cake, cookie and bread recipes; but that doesn’t mean you have to pay someone else to make it. Here’s how to make your own baking powder:


  • 1 teaspoon baking soda
  • 2 teaspoons cream of tartar
  • 1 teaspoon corn starch (optional)


  1. Mix the baking soda and cream of tartar together until well combined. Use immediately.

Note: Yield – One tablespoon of baking powder.

To store baking powder:

Add a teaspoon of corn starch to the mixture, and stir. This will absorb any moisture from the air, and prevent the baking powder from reacting before you need it. Store in an air-tight container.

Did You Know?

Most commerically-produced baking powder contains aluminum–sodium aluminum sulfate to be exact. Make your own baking powder, and keep your baked goods aluminum-free.
