Homemade Baking Powder

INGREDIENTS

• 1 tsp baking soda
• 2 tsp cream of tartar
• 1 tsp ​cornstarch, optional

 

INSTRUCTIONS

1. Mix the baking soda and cream of tartar together until well combined. This will give you one tablespoon of baking powder.
2. Add a cornstarch to the mixture if you plan to store your baking powder.
3. Stir.
4. Store in an air-tight container between uses to keep the baking soda fresh.

Notes:  It’s aluminum-free. It doesn’t contain sodium aluminum sulfate, like most store-bought baking powders. Corn-free. Just leave the cornstarch out, or use arrowroot powder in its place, and your baking powder won’t contain corn. Gluten-free. If you add the cornstarch, it will contain corn gluten, but that’s not the type of gluten that affects people with Celiac disease or gluten sensitivity.
Your baking powder will only be as good as the ingredients that you put into it, so make sure your baking soda and cream of tartar are fresh. This will absorb any moisture from the air and prevent the baking powder from clumping or reacting before you need it. Want to make a bigger batch? Just stick to the ratio of two parts cream of tartar to one part baking soda, and it’ll come out great. Since baking powder loses its potency over time, it’s best to make no more than you can use in a month.
