Homemade Baking Powder Substitute
Make your own baking powder substitute by combining three other pantry ingredients.
Cream of Tartar
Cornstarch (or Arrowroot Powder)
Mix the three ingredients together. This will equal one teaspoon of baking powder substitute.
This recipe can also be made in larger batches. Just remember the ratio of 1 part baking soda + 2 parts cream of tartar + 1 part cornstarch (or arrowroot powder).
