Your best substitutes for baking powder
The fastest replacement is baking soda plus an acid. Mix one-third teaspoon of baking soda with one-half teaspoon of cream of tartar, and use that mixture in place of one teaspoon of baking powder. The acid in the cream of tartar reacts with the baking soda to create the lift that baking powder would have provided. This works in almost any recipe — cakes, muffins, pancakes, biscuits.
If you don't have cream of tartar, use baking soda with lemon juice or vinegar instead. Mix one-quarter teaspoon of baking soda with one-half teaspoon of lemon juice or white vinegar, let it sit for a few seconds until it stops fizzing, then add it to your batter right away. The reaction happens fast, so work quickly once you've mixed them.
For recipes where you need a gentler rise or where the acid flavor matters less, self-rising flour can replace both baking powder and salt. One cup of self-rising flour contains about one and a half teaspoons of baking powder already mixed in. If your recipe calls for one cup of all-purpose flour and one teaspoon of baking powder, use one cup of self-rising flour instead and skip the baking powder.
Key Takeaways
- Baking soda mixed with cream of tartar (one-third teaspoon soda to one-half teaspoon cream of tartar) replaces one teaspoon of baking powder in any recipe.
- Baking soda with lemon juice or vinegar works the same way but requires you to mix and use it when ready because the reaction starts right away.
- Self-rising flour already contains baking powder, so you can swap it directly for all-purpose flour if your recipe calls for baking powder.
- Whipped egg whites add lift to cakes and soufflés but work differently than baking powder and won't work in all recipes.
When baking soda alone is enough
If your recipe already contains an acidic ingredient — buttermilk, yogurt, sour cream, lemon juice, vinegar, brown sugar, or molasses — you may not need cream of tartar at all. Baking soda reacts with the acid that's already in the batter. Use one-quarter teaspoon of baking soda for every one-half cup of acidic liquid in the recipe.
This is why recipes for pancakes made with buttermilk or sour cream often call for baking soda alone rather than baking powder. The buttermilk provides the acid. If you use this method, mix the baking soda into the dry ingredients first, then combine everything else. Don't let the batter sit — the reaction starts when ready and the bubbles will escape if you wait.
Self-rising flour as a one-to-one swap
Self-rising flour is all-purpose flour with baking powder and salt already mixed in. One cup contains roughly one and a half teaspoons of baking powder and one teaspoon of salt. If your recipe calls for one cup of all-purpose flour and one teaspoon of baking powder, you can use one cup of self-rising flour and reduce the salt elsewhere in the recipe.
This works well for biscuits, muffins, and quick breads. It's less useful for recipes where the amount of baking powder is much higher than what self-rising flour contains, or where you need to control the salt level precisely. Always check the label on your self-rising flour — brands vary slightly in how much baking powder they include.
Whipped egg whites for cakes and soufflés
Whipped egg whites create lift through air bubbles rather than a chemical reaction. Separate the eggs, beat the whites until stiff peaks form, then fold them gently into your batter at the end. This method works for angel food cakes, chiffon cakes, and soufflés where the structure depends on trapped air.
Whipped egg whites don't work in recipes that need baking powder's chemical rise — they won't help a dense batter rise evenly, and they break down if you stir the batter too much after folding them in. Use this method only for recipes designed around it or for cakes where you're comfortable with a denser crumb.
Potassium bicarbonate for low-sodium baking
Potassium bicarbonate is a salt substitute that works like baking soda but without the sodium. Use it in a one-to-one ratio in place of baking soda, then pair it with an acid the same way you would with regular baking soda. One-third teaspoon of potassium bicarbonate plus one-half teaspoon of cream of tartar replaces one teaspoon of baking powder.
This option costs more than baking soda and is harder to find — health food stores and online retailers carry it more often than supermarkets. It's useful if you're on a sodium-restricted diet and bake frequently. The flavor is nearly identical to regular baking soda.
What doesn't work as a replacement
Yeast is not a substitute for baking powder. Yeast ferments and creates carbon dioxide over hours, while baking powder reacts in minutes. Yeast also creates a different flavor and texture — bread made with yeast has a completely different crumb structure than a cake made with baking powder.
Club soda and other carbonated liquids add temporary bubbles but won't create the sustained rise that baking powder provides. The bubbles escape too quickly. Some recipes use club soda as an extra ingredient alongside baking powder to lighten the texture, but it can't replace baking powder on its own.
How to measure and mix your substitute
The most reliable substitute is baking soda plus cream of tartar. For every one teaspoon of baking powder your recipe calls for, use one-third teaspoon of baking soda and one-half teaspoon of cream of tartar. Mix them together in a small bowl before adding them to your dry ingredients.
If you're using baking soda with lemon juice or vinegar, mix one-quarter teaspoon of baking soda with one-half teaspoon of acid in a small cup. Watch it fizz for a few seconds, then add it to your batter when ready. Don't wait — the reaction is already happening and the bubbles will be gone in a minute or two.
For recipes with acidic ingredients already in them, measure one-quarter teaspoon of baking soda for every one-half cup of buttermilk, yogurt, sour cream, or other acidic liquid. Mix the baking soda into your dry ingredients, then combine everything and bake right away.
Frequently Asked Questions
Can I use baking soda alone without an acid?
No. Baking soda needs an acid to create the chemical reaction that produces lift. Without an acid, it won't rise. If your recipe has no acidic ingredients, you must add cream of tartar, lemon juice, or vinegar to make baking soda work.
Does the substitute change the taste of my baked goods?
Baking soda with cream of tartar tastes the same as baking powder. Baking soda with lemon juice or vinegar may leave a slight tang if you use too much, so measure carefully. Self-rising flour contains salt, so you may need to reduce salt elsewhere in the recipe to avoid oversalting.
Can I make a batch of baking powder substitute ahead of time?
Yes, for baking soda and cream of tartar. Mix them together and store in an airtight container for up to a month. Don't make a batch with lemon juice or vinegar — the reaction starts when ready and the mixture won't keep. Mix that one fresh each time you bake.
What if I only have baking soda and no acid at all?
If your recipe contains buttermilk, yogurt, sour cream, brown sugar, molasses, lemon juice, or vinegar, you can use baking soda alone with those ingredients. If your recipe has none of those, you'll need to get cream of tartar, lemon juice, or vinegar before you can bake.
Does the substitute work the same in all recipes?
Baking soda with cream of tartar works in cakes, muffins, pancakes, biscuits, and most quick breads. Whipped egg whites work only in recipes designed for them, like angel food cake. Self-rising flour works for biscuits and quick breads but not for recipes where you need precise control over salt or baking powder amount.
