Ingredients Needed
- Cream of Tartar When combined with baking soda and moisture, cream of tartar creates carbon dioxide gas bubbles that help baked goods rise and become light and fluffy.
- Baking Soda Baking soda is the alkaline ingredient that reacts with the (acidic) cream of tartar. This chemical reaction produces the leavening power needed to lift cakes, muffins, biscuits, and other baked treats.
- Cornstarch. While Cornstarch is optional, it is recommended as but it absorbs moisture and helps prevent the cream of tartar and baking soda from reacting prematurely during storage. It also keeps the mixture free-flowing and easy to measure.

Tips for making the best DIY baking powder.
Use fresh ingredients to make this recipe. Also, it is a good idea to the expiration dates close to one another so that you do not waste fresh ingredients when part of the baking powder expires.
More helpful tips for you.
- Measure your ingredients carefully. Accurate measurements ensure the proper balance between the acidic and alkaline ingredients.
- When whisking the ingredients together, make sure the ingredients are evenly and well combined so the baking powder performs consistently in your recipes.

FAQ
- How much homemade baking powder equals store-bought baking powder?
Use this homemade baking powder as a 1:1 substitute for store-bought baking powder. If a recipe calls for 1 teaspoon of baking powder, use 1 teaspoon of this homemade version. - Can I make homemade baking powder without cornstarch?
Yes. Cornstarch is optional and primarily helps absorb moisture and prevent the ingredients from reacting during storage. If you leave it out, store the mixture in an airtight container and use it relatively quickly. - Can I use baking soda instead of baking powder in recipes?
I do not recommend it. Baking soda requires an acidic ingredient, such as lemon juice, vinegar, or buttermilk, to activate. Baking powder already contains both an acid and a base, making it suitable for recipes without additional acidic ingredients. These ingredients also leaven differently. - How do I know if my homemade baking powder is still active?
Add 1 teaspoon of baking powder to ⅓ cup hot water. If it fizzes and bubbles immediately, it's still active and ready to use. - Is homemade baking powder aluminum-free?
Yes, as long as you stick to the 'aluminum-free' ingredients. This homemade baking powder contains only cream of tartar, baking soda, and optional cornstarch, making it naturally aluminum-free
Variations.
- Cornstarch-Free Homemade Baking Powder. Spoiler... you can skip the cornstarch if you plan to use the baking powder right away. The cream of tartar and baking soda will still provide the leavening power needed for baking.
- Make this into Arrowroot Baking Powder by replacing the cornstarch with an equal amount of arrowroot powder. This is a great option if you are avoiding corn products.
- Or make this into a Tapioca Starch Baking Powder. Substitute the cornstarch with tapioca starch for a similar moisture-absorbing effect and longer shelf life.

How to store baking powder.
This homemade baking powder should keep for up to six months when stored in an airtight container and in a cool, dry pantry. If it becomes clumpy or loses its fizzing power, make a fresh batch. To check potency, whisk in a teaspoon of baking powder into ⅓ cup of hot water. If it bubbles vigorously, it is still active and ready to use.
