The fastest substitutes for baking powder

The best replacement depends on what else is in your recipe. If your batter already contains an acidic ingredient—buttermilk, yogurt, lemon juice, vinegar, or brown sugar—use baking soda alone. Use one-third the amount of baking soda that the recipe calls for in baking powder. For example, if the recipe needs 1 teaspoon of baking powder, use ⅓ teaspoon of baking soda.

If your recipe has no acidic ingredient, make a substitute by mixing baking soda with an acid. The most reliable method is baking soda plus cream of tartar: mix 1 part baking soda with 2 parts cream of tartar. This ratio mimics commercial baking powder. You can also use baking soda mixed with lemon juice, vinegar, or buttermilk, though these work best when mixed just before you add them to the batter.

For recipes that need multiple teaspoons of baking powder, having cream of tartar on hand is worth the small cost. It stores indefinitely and works in nearly every baked good. If you do not have it, the acid-and-soda method still works—you just need to work faster so the reaction does not happen before the batter hits the oven.

Key Takeaways

  • Baking soda alone works in recipes with acidic ingredients like buttermilk, yogurt, or vinegar, using one-third the amount the recipe calls for in baking powder.
  • Baking soda mixed with cream of tartar (1 part soda to 2 parts tartar) creates a substitute that works in any recipe and stores for months.
  • Mixing baking soda with lemon juice or vinegar works but must be done just before adding to the batter so the reaction does not happen too early.
  • Recipes that rely on baking powder for rise will not work without a leavening agent, so substitutes are necessary—skipping it entirely will produce dense, flat results.

Using baking soda when your recipe already has acid

Check your ingredient list for buttermilk, sour cream, yogurt, brown sugar, molasses, honey, lemon juice, vinegar, or cocoa powder. Any of these creates the acid needed to set up baking soda. When you find one, you can replace baking powder with baking soda at a 1-to-3 ratio: one-third teaspoon of baking soda for every teaspoon of baking powder the recipe calls for.

This works because baking powder is already a mixture of baking soda and acid (usually cream of tartar or sodium aluminum sulfate). When you add baking powder to a wet batter, the acid and soda react when ready, creating carbon dioxide bubbles that make the batter rise. If acid is already present in your recipe, the soda alone will do the same job—you just need less of it because you are not wasting any on a second acid source.

The timing matters. Baking soda reacts as soon as it touches liquid, so mix your dry ingredients into your wet ingredients quickly and get the batter into the oven within a few minutes. If you let it sit, the bubbles will escape and your cake or muffins will be dense.

Making a baking powder substitute with cream of tartar

Mix 1 teaspoon of baking soda with 2 teaspoons of cream of tartar, then use this mixture as you would baking powder—measure it at a 1-to-1 ratio. If a recipe calls for 1 teaspoon of baking powder, use 1 teaspoon of your soda-and-tartar mix. This ratio is the same as most commercial baking powders, so it works in any recipe without adjustment.

You can make a larger batch and store it in an airtight container for up to three months. Mix 1 tablespoon of baking soda with 2 tablespoons of cream of tartar, then add 1 tablespoon of cornstarch or arrowroot powder if you want to prevent clumping. Label the container and keep it away from moisture. This homemade version works identically to store-bought baking powder in cakes, cookies, quick breads, and pancakes.

Cream of tartar is inexpensive and lasts years in the pantry, so buying a small container is practical if you bake regularly. It is sold in the spice aisle of most grocery stores and online. One container will make dozens of batches of homemade baking powder.

Using baking soda with lemon juice or vinegar

If you have neither cream of tartar nor an acidic ingredient already in your recipe, you can create the acid on the spot. Mix ⅓ teaspoon of baking soda with ¾ teaspoon of lemon juice or white vinegar. Let it sit for 30 seconds—you will see it bubble and foam. Then add this mixture to your batter when ready and get it into the oven right away.

This method works, but the timing is tight. The reaction starts as soon as the acid and soda meet, and it peaks within seconds. If you wait too long before adding the batter to the oven, the bubbles will escape and your baked good will not rise properly. For this reason, it is best used in recipes where you can mix and bake quickly, like pancakes or waffles, rather than in doughs that need to rest.

The flavor impact is usually minimal because the amount of lemon juice or vinegar is small, but taste-sensitive recipes like angel food cake or delicate sponge cakes may pick up a slight tang. If that concerns you, cream of tartar is the safer choice.

What not to use as a substitute

Self-rising flour is not a substitute for baking powder because it already contains salt and flour mixed in. If you use it, you will throw off the salt balance and the flour ratio of your recipe. Yeast is not a substitute either—it works differently, takes hours to rise, and produces a different texture. Baking soda alone without acid will not work in recipes that have no acidic ingredient, because the soda needs acid to set up and create lift.

Whipped egg whites can add some lift to cakes and soufflés, but they do not replace baking powder. They work through a different mechanism (air trapped in foam) and are used alongside leavening agents, not instead of them. If a recipe relies on baking powder for rise, you need a chemical leavening agent to get the same result.

Timing and oven temperature when using substitutes

Homemade baking soda-and-acid mixtures react faster than commercial baking powder, so work quickly once you mix them into your batter. Get the batter into a preheated oven within 5 to 10 minutes. If you are making pancakes or waffles, cook them when ready after mixing.

Oven temperature does not need to change. Use the temperature the original recipe calls for. The substitute will work at the same heat—it just needs to get into the oven before the bubbles escape. If you are worried about your baked good browning too quickly, you can tent it loosely with foil for the first half of baking, then remove the foil to finish browning.

One exception: if you are using a large amount of baking soda (more than ½ teaspoon), the batter may brown too quickly because baking soda promotes browning. If this happens in your first attempt, lower the oven temperature by 25 degrees Fahrenheit and add a few minutes to the baking time.

Substitutes for specific baked goods

Cakes and cupcakes: Use the cream of tartar method (1 part soda to 2 parts tartar) at a 1-to-1 ratio with the original baking powder amount. This gives you the most reliable rise and crumb structure. If your cake recipe includes buttermilk or sour cream, you can use baking soda alone at one-third the baking powder amount.

Cookies: Baking soda with cream of tartar works well. If your cookie dough includes brown sugar, molasses, or honey, use baking soda alone. Cookies are forgiving because they do not rely on a tall, even rise the way cakes do.

Quick breads and muffins: These almost always contain acidic ingredients like buttermilk, yogurt, or fruit. Use baking soda alone at one-third the baking powder amount. Muffins and quick breads bake quickly, so the timing is less critical than with cakes.

Pancakes and waffles: These contain buttermilk or yogurt, so baking soda alone works. Use one-third the baking powder amount. Cook them when ready after mixing so the bubbles do not escape before they hit the griddle.

Frequently Asked Questions

Can I use baking soda and vinegar instead of baking powder in any recipe?

Yes, but you need to work quickly. Mix ⅓ teaspoon baking soda with ¾ teaspoon vinegar, let it bubble for 30 seconds, then add it to your batter and bake when ready. The reaction happens fast, so this method works best for pancakes, waffles, and quick breads rather than cakes that need time to set before baking.

What if I do not have cream of tartar or any acidic ingredients?

Lemon juice or white vinegar will work in a pinch. Mix ⅓ teaspoon baking soda with ¾ teaspoon of either one, let it sit for 30 seconds, then add to your batter right away. If you have neither, you can order cream of tartar online or check a nearby grocery store—it is inexpensive and lasts for years.

Will my baked good taste different if I use a substitute?

Not usually. Baking soda with cream of tartar tastes identical to commercial baking powder. Baking soda with lemon juice or vinegar may add a slight tang if you use a lot, but the amount needed for leavening is small enough that most people do not notice it.

How much baking soda do I use if my recipe calls for double-acting baking powder?

Double-acting baking powder reacts twice—once when wet and again when heated. A homemade substitute with cream of tartar mimics this behavior closely enough for home baking. Use the cream of tartar method at a 1-to-1 ratio: if the recipe calls for 2 teaspoons of baking powder, use 2 teaspoons of your baking soda and cream of tartar mix.

Can I make a big batch of baking soda substitute and store it?

Yes, if you use cream of tartar. Mix 1 tablespoon baking soda with 2 tablespoons cream of tartar and store in an airtight container for up to three months. Add 1 tablespoon of cornstarch to prevent clumping. Do not make large batches with lemon juice or vinegar—these need to be mixed fresh because the reaction starts when ready.
