No Baking Powder Substitute: A Quick Homemade Mix That Works

A no baking powder substitute you can mix in minutes uses baking soda, cream of tartar, and a little cornstarch. Use it in the same volume as baking powder, then get the batter into the oven promptly for the best rise.

Ingredients

3/4 teaspoon (3.5 g) baking soda
1 1/2 teaspoons (4.5 g) cream of tartar
3/4 teaspoon (2 g) cornstarch

This makes 1 tablespoon (about 12 g) of substitute, enough to replace 1 tablespoon of baking powder in a recipe. The measurements are small, so use level measuring spoons rather than estimating by eye. Cream of tartar supplies the acid that reacts with baking soda; cornstarch helps keep the powders dry and free-flowing. If you do not have cornstarch, you can leave it out and use the mix right away.

Instructions

Measure the powders. Spoon the baking soda, cream of tartar, and cornstarch into a small, completely dry bowl. Break up any lumps in the baking soda or cream of tartar with the back of a spoon.
Whisk thoroughly. Stir for about 30 seconds, scraping the bottom and sides so the ingredients are evenly dispersed. This matters: a pocket of baking soda can leave a bitter, soapy taste, while a pocket of cream of tartar may not provide even leavening.
Use it in place of baking powder. Measure the amount your recipe calls for, using this mix one-for-one by volume. For example, replace 2 teaspoons of baking powder with 2 teaspoons of the homemade mix. This batch makes 1 tablespoon, or 3 teaspoons.
Mix the batter and bake promptly. Add the substitute with the dry ingredients, combine the wet and dry ingredients as directed, and put the batter in the oven without an unnecessary wait. The acid and baking soda begin reacting as soon as they become damp. The homemade blend gives a useful lift, but it does not have the same controlled, two-stage release as many commercial baking powders.

This is a dry mix, not a separate step to add to the wet ingredients. Keeping it with the other dry ingredients helps spread the leavening evenly through a cake, biscuit, pancake, muffin, or quick-bread batter. Follow the original recipe’s mixing method and oven temperature; the substitute cannot correct an oven that is too cool or a batter that has been overmixed.

Tips

Make only what you need. The proportions scale easily: for each teaspoon of baking powder, combine 1/4 teaspoon baking soda, 1/2 teaspoon cream of tartar, and 1/4 teaspoon cornstarch. Measure carefully, especially when scaling down, because too much baking soda can make baked goods taste alkaline.
Keep every tool dry. A damp spoon or wet bowl can start the reaction before the mix reaches the batter. If you are preparing several batches, mix each in a clean, dry bowl and do not return unused powder to a container that may be damp or contaminated.
Do not wait after mixing. Unlike many commercial double-acting baking powders, this homemade version relies on an acid that reacts quickly when wet. Have the oven preheated and the pan ready before you combine wet and dry ingredients.
Check whether the recipe already has an acid. Yogurt, buttermilk, citrus juice, vinegar, and some natural cocoa powders are acidic. The cream of tartar in this formula supplies the acid for the baking soda, so the mix is straightforward in most recipes. If a recipe was specifically balanced around an acidic ingredient and baking soda, changing its leavener can affect flavor and texture; follow a tested version of that recipe rather than adding extra baking soda by guesswork.

Serving Suggestions

This substitute is designed to go into a baking recipe, rather than be served on its own. Use it in pancakes or waffles for a quick breakfast, muffins for a snack, or a simple cake or quick bread for dessert. It can also work in many biscuit and scone recipes, although those recipes often depend on cold fat and careful handling as well as leavening. The finished food should be served according to its own recipe: pancakes are best warm, while cakes and quick breads are usually easier to slice after they have cooled.

For pancakes, measure the replacement into the dry ingredients and cook the batter soon after mixing. For muffins, distribute the powder through the flour before adding the wet ingredients to avoid isolated bitter spots. In biscuits, avoid kneading more than the recipe calls for; extra handling can make them firm even when the leavening is correctly measured. This blend does not add flavor intended for a topping, so choose toppings that suit the baked item, such as fruit, syrup, butter, or a simple glaze.

Variations

Make a smaller, single-use amount: For 1 teaspoon of baking powder, mix 1/4 teaspoon baking soda with 1/2 teaspoon cream of tartar and 1/4 teaspoon cornstarch. Whisk them together well and use the full teaspoon in one recipe. This is handy when you are short on baking powder but do not want to store a larger batch.

Skip the cornstarch: If you have no cornstarch, combine the baking soda and cream of tartar in the same proportions and use the blend immediately. Cornstarch is mainly there to absorb small amounts of moisture and help the dry mix stay loose; it is not the ingredient that creates the lift. Without it, avoid storing the mixture because it is more vulnerable to clumping.

Use an egg-white method for suitable batters: Some sponge cakes and certain pancakes can get lift from whipped egg whites folded gently into the batter. This is not a direct substitute for baking powder in every recipe: it adds air rather than using a chemical acid-and-base reaction, and it changes the texture. Use it only when the recipe’s style and method support whipped whites, and fold carefully so you do not knock out the air.

Consider self-rising flour when appropriate: Self-rising flour contains flour, salt, and leavener, so it can help when a recipe already allows you to change the flour. It is not a spoon-for-spoon replacement for baking powder. You must adjust the flour and salt amounts to match a recipe written for self-rising flour; simply adding it on top of the listed flour can make the proportions wrong.

Try carbonated water only in a narrow case: Club soda can provide some bubbles in a thin batter, such as a light pancake batter, if you replace part of the recipe’s liquid with it and cook promptly. It is less dependable than this measured dry mix, loses carbonation as it sits, and will not work well for every cake, biscuit, or dense quick bread. It should be treated as a recipe-specific adjustment, not a universal replacement.

Storage and Reheating

For the most dependable lift, make this substitute just before using it. If you have leftover dry mix, keep it in a clean, airtight container in a cool, dry cupboard and label it with the ingredients and date. Use it within about 1 month for best results, and discard it if it becomes damp, hard, or develops an unusual smell. Do not store it in a container that has held a wet spoon or been placed near steam from a kettle or stovetop.

The substitute itself is not cooked, so it does not need reheating. If you have leftover baked goods, follow the storage directions for that particular food. As a general rule, refrigerate perishable baked items within 2 hours; many cooked leftovers keep 3–4 days in the refrigerator. Reheat leftovers to 165°F (74°C), checking with a food thermometer where appropriate. Plain, shelf-stable baked goods may have different storage needs, so use the original recipe’s directions.

Frequently Asked Questions

Can I replace baking powder with baking soda alone?
No, not in a one-for-one swap. Baking soda needs an acid to react, and using it alone can leave a strong alkaline taste and produce poor rise. This blend includes cream of tartar to provide the acid, which is why it is a more dependable direct substitute.

How much homemade substitute replaces 1 teaspoon of baking powder?
Use 1 teaspoon of the finished mix. To make that amount, combine 1/4 teaspoon baking soda, 1/2 teaspoon cream of tartar, and 1/4 teaspoon cornstarch. The full recipe above makes 1 tablespoon, enough to replace 1 tablespoon of baking powder.

Will this make my baked goods rise exactly like commercial baking powder?
Not always. The mixture provides the key acid-and-base reaction, but commercial baking powders are often double-acting, releasing gas both when wet and as they heat. This homemade version reacts quickly once liquid is added, so prompt baking is important. Delicate cakes or recipes that require a specific commercial product may have a different texture or height.

Can I use lemon juice or vinegar instead of cream of tartar?
They can provide acid in some baking recipes, but they are liquids and are not a simple equal-volume replacement for cream of tartar in this dry mix. A recipe’s liquid and acid balance matters, and an improvised swap may change the crumb or flavor. If using an acid-and-baking-soda method from another recipe, follow its specific quantities and reduce other liquid only as instructed.

Can I make this substitute ahead?
You can, but it is most reliable when freshly mixed. Store any extra in a tightly sealed, dry container for up to about 1 month, then check that it is still loose and dry before measuring. If you are unsure whether it has absorbed moisture, make a fresh batch rather than risking a weak rise.

What if I do not have cream of tartar?
There is no equally reliable dry, one-for-one version of this particular substitute without an acid ingredient. If your recipe allows a suitable acidic liquid, look for a recipe-specific baking soda and acid conversion. Otherwise, consider a suitable recipe that uses whipped egg whites or self-rising flour, rather than adding baking soda alone and hoping it will work.
