Learn how to make homemade baking powder using just three simple ingredients! This easy DIY recipe is a perfect substitute for store-bought baking powder.
Mix the Ingredients: In a small bowl, whisk together 2 teaspoons cream of tartar and 1 teaspoon baking soda until well combined.
Optional Step for Storage: If you’re making a larger batch or plan to store it, add 1 teaspoon of cornstarch. This absorbs moisture and keeps the baking powder from clumping.
Store: Transfer to an airtight container or small jar. Keep in a cool, dry place.
Notes
How to Use Homemade Baking Powder
Use your DIY baking powder in a 1:1 ratio in any recipe that calls for baking powder. For example, if a recipe calls for 1 tablespoon of baking powder, replace it with 1 tablespoon of homemade baking powder.
Tips for Success
Freshness Matters: Always check that your baking soda is still active for the best results.
Why Cornstarch? Cornstarch helps prevent clumping but isn’t necessary if you’re using it immediately.
Scale Up for Later: Make a larger batch to store for future recipes (triple or quadruple the ingredients).
