Baking Powder Substitute

Replace baking powder with baking soda and cream of tartar.

About Baking Powder Substitute

Baking powder is baking soda plus an acid, so recreating it needs one-quarter the soda with half again as much cream of tartar. Running out of baking powder is common, and this substitution keeps batters rising when the two components are on hand.

Soda = powder x 0.25; cream of tartar = powder x 0.5
