Baking soda and baking powder are often used interchangeably, but they are actually two very different ingredients. Baking soda is a pure leavening agent, while baking powder is a leavening agent that contains other ingredients, like cream of tartar.

Baking powder is a raising agent that is commonly used in baking. It is a mixture of an acid and a base and reacts with other ingredients in the batter or dough to produce carbon dioxide gas, which causes the dough or batter to rise. Baking soda is also a raising agent but it works differently to baking powder and should not be used as a direct replacement.
What is Baking Soda?
Baking soda is a white crystalline powder (NaHCO3) better known as sodium bicarbonate, bicarbonate of soda, sodium hydrogen carbonate, or simply baking soda. It has an alkaline taste and is often used as a leavening agent in baking. When used in cooking, it reacts with other ingredients to release carbon dioxide gas, which causes foods to rise. Because of its reaction with other ingredients, it should be added last to batters.
What is Baking Powder?
Baking powder is a leavening agent used in baking. It’s a combination of baking soda, an acid (usually cream of tartar), and a filler (such as cornstarch). When combined with moisture and heat, the baking powder reacts to produce carbon dioxide gas, which helps to leaven or rise the dough.
The Difference Between Baking Soda and Baking Powder
Baking soda and baking powder are often used interchangeably, but they are actually quite different.
Baking soda is a leavening agent that is activated by an acid, typically in the form of yogurt, buttermilk, citrus juice, or cream of tartar. Baking soda produces carbon dioxide gas as it bakes, which helps to leaven baked goods. It is best used in recipes that also call for an acidic ingredient.
Baking powder is also a leavening agent that is activated by an acid. However, it contains both an acid and a base (usually in the form of sodium bicarbonate), which react with each other to produce carbon dioxide gas. Baking powder does not require an acidic ingredient to be activated and can be used in recipes that do not contain one.
Can I Use Baking Soda Instead of Baking Powder?
Baking soda is a leavening agent that is used in baking to promote rise, or expansion, of the batter or dough. When used in combination with an acidic ingredient (such as yogurt, chocolate, buttermilk, honey), baking soda releases carbon dioxide gas bubbles, which causes the batter or dough to rise. Baking powder is a mixture of baking soda and an acid (usually cream of tartar). When dissolved in liquid, it releases carbon dioxide gas bubbles and expands the batter or dough.
In conclusion, you can use baking soda in place of baking powder only if you increase the amount of acid in the recipe–which you’ll need to do if you want to avoid a bitter taste. You can use lemon juice, buttermilk, or yogurt to do this.
