Question: 2 teaspoons cream of tartar equals how much baking powder?
Answer: When substituting for cream of tartar, you must also substitute for the baking soda. If your recipe calls for baking soda and cream of tarter, I would just use baking powder. One (1) teaspoon baking powder is equivalent to 1/4 teaspoon baking soda plus 1/2 teaspoon cream of tartar.
