Baking Powder Substitute
Out of baking powder? Here's what actually works, and exactly how much to use.
Real substitutes for 1 teaspoon of baking powder
Baking soda + cream of tartar
1/4 teaspoon baking soda + 1/2 teaspoon cream of tartar per teaspoon needed
The most common substitute; mix right before using since it starts reacting immediately.
Baking soda + lemon juice or vinegar
1/4 teaspoon baking soda + 1/2 teaspoon lemon juice or vinegar per teaspoon needed
Works similarly, but adjust other liquid in the recipe slightly since this adds a little.
Frequently Asked Questions
What can I use instead of baking powder?
Mix 1/4 teaspoon baking soda with 1/2 teaspoon cream of tartar for every teaspoon of baking powder the recipe calls for. Mix it right before using, since the reaction starts as soon as the two combine with moisture.
Can I use baking soda alone instead of baking powder?
No — baking soda needs an acid to react and produce lift, while baking powder already contains that acid. Using baking soda alone in a recipe designed for baking powder will leave it flat and can taste metallic.
Does homemade baking powder work exactly the same?
It works for immediate lift the same way single-acting baking powder does, but commercial baking powder is usually double-acting (it reacts once when wet and again when heated) — homemade substitutes react mostly right away, so bake promptly after mixing.
