Baking powder and baking soda are both leavening agents that help batter rise. You can use them interchangeably in most recipes, but there are a few key differences.

Baking powder and baking soda are both key ingredients in many recipes, but they are NOT interchangeable. Baking powder is a leavening agent that contains baking soda and an acid (such as cream of tartar). When mixed with liquid ingredients, it creates bubbles of carbon dioxide gas that cause batter to rise. Baking soda, on the other hand, is a single ingredient that only creates bubbles of carbon dioxide gas when combined with an acidic ingredient (such as vinegar or yogurt). In short, you need baking powder AND an acidic ingredient to create the desired chemical reaction in your recipe.
What is Baking Powder?
Baking powder is a replacement for yeast in cakes and quick breads. It’s a mixture of cream of tartar, a dry acid, and baking soda. Baking powder is manufactured with either sodium bicarbonate or potassium bicarbonate. When used with baking soda, it provides double action: an immediate release of CO2 when it comes into contact with moisture and heat, plus a slow reaction that continues during baking.
What is Baking Soda?
Baking soda is a white crystalline powder (NaHCO₃) better known to chemists as sodium bicarbonate, bicarbonate of soda, sodium hydrogen carbonate, or simply baking soda. When baking soda is mixed with an acidic ingredient (such as yogurt, chocolate, buttermilk, honey, or molasses), it reacts by producing carbon dioxide gas and water. This release of gas makes baked goods light and airy.
The Difference Between Baking Powder and Baking Soda
Baking powder and baking soda are both leavening agents, which means they help baked goods to rise. Baking soda is a single-ingredient leavener, while baking powder is a combination of baking soda and an acid. When used correctly, either can help baked goods to rise; however, they should not be used interchangeably.
Baking powder is made up of baking soda and an acid, usually cream of tartar. When moisture is added, the baking powder reacts and creates carbon dioxide gas. This gas helps baked goods to rise. Baking powder is a quick-acting leavener, which means that it starts working as soon as it’s added to the batter or dough. Because of this, quick breads and cakes made with baking powder should be baked immediately after mixing.
Baking soda is a form of sodium bicarbonate. When it’s combined with an acid, it creates carbon dioxide gas. This gas helps baked goods to rise. Baking soda is a slow-acting leavener, which means that it takes time for the carbon dioxide gas to be created. For this reason, recipes that call for baking soda often also include an acidic ingredient, such as buttermilk or yogurt. These acidic ingredients help to activate the baking soda so that the carbon dioxide gas can be created and the baked goods can rise appropriately.
Can I Use Baking Powder Instead of Baking Soda?
The short answer to the question is- no, you cannot use baking powder instead of baking soda. Baking powder is a combination of baking soda and an acidic salt. When combined with liquid, it starts to effervesce or bubble. The reaction between the baking soda and acid creates carbon dioxide gas, which is what makes baked goods rise. Baking powder also contains cornstarch, which prevents caking and keeps the powder dry.
So, can you use baking powder instead of baking soda? Baking powder can be used in place of baking soda, but there are a few things to keep in mind. Because it contains both an acid and a base, it will react with both acidic and basic ingredients, which means it has a neutralizing effect. That’s why it’s often used in recipes that call for both acidic and basic ingredients. If you use baking powder in place of baking soda, you will need to use twice as much baking powder for the same amount of leavening power. This is because baking soda is about four times as strong as baking powder. Finally, keep in mind that using too much baking powder can actually make your baked goods taste bitter, so be sure to follow the recipe and only use as much as is called for.
