I make my own homemade baking powder to avoid some ingredients in store-bought baking powder. Homemade baking powder is very easy to make. You will need Cream of tartar and baking soda, and optional starch or arrowroot powder. You can mix up the ingredients and store your baking powder in a glass jar. However, I don’t mix them up and just use cream of tartar and baking soda separately following the proportions.
Most store-bought baking powders contain sodium aluminum sulfate. If you want to avoid aluminum in your baked goods, then making a homemade baking powder can be a solution. Because of aluminum store-bought baking powder usually tastes metallic. This is another reason to use a homemade one.
This homemade baking powder reacts with the fluids in a recipe. That’s why put your baked goods in the oven as soon as possible after you add the baking powder.
If you need a baking powder which reacts when it’s heated in the oven, then you can try the Rumford Baking powder, which is aluminum-free, non-GMO, and contains no additives or preservatives.
HOMEMADE BAKING POWDER with Cream of Tartar
- 2 teaspoons of Cream of Tartar
- 1 teaspoon of Baking soda
- 1 teaspoon of Potato starch or Arrowroot powder
How to make homemade baking powder:
1. Mix 2 teaspoons of cream of tartar and 1 teaspoon of baking soda until well combined. This mixture will give you one tablespoon or 3 teaspoons of baking powder.
2. If you want to store your baking powder, then add 1 teaspoon of potato starch or arrowroot powder to the mixture and stir well. The starch will absorb extra moisture and will prevent the baking powder from clumping or reacting. Store the baking powder mixture in an air-tight container.
If you want to make a bigger batch, mix 2 parts of cream of tartar, 1 part baking soda, and 1 part of starch. For example, 100 grams of Cream of tartar, 50 grams of baking soda, and 50 grams of starch.
The baking powder loses its potency over time, so make no more amount than you can use within a month.
