If you are out of baking soda, baking powder is the best substitute, but because it is milder you need about three times as much. So for 1 teaspoon of baking soda, use around 3 teaspoons of baking powder. Keep in mind this adds extra acid and salt, which may slightly change the taste and texture.
1 tsp baking soda = about 3 tsp baking powder. Baking powder is milder, so you need roughly three times the amount.
Using Baking Powder Instead
Baking soda is pure and strong, while baking powder already contains acid and starch, so it is weaker. Triple the amount to get a similar rise: three teaspoons of baking powder for each teaspoon of soda. Because you are adding more, expect a little extra saltiness and a possible change in texture.
Keep the Recipe Balanced
Since baking soda usually reacts with an acid in the recipe, switching to baking powder can leave that acid, like buttermilk, unbalanced, so results vary. For the full picture, see baking soda vs baking powder. Precise measuring spoons keep the ratio right.
Frequently Asked Questions
Can I use baking powder instead of baking soda?
Yes, but use about three times as much, since baking powder is milder. It may add a slightly salty taste and change the texture a little.
Why is baking soda stronger than baking powder?
Baking soda is pure sodium bicarbonate, while baking powder is diluted with acid and starch, so a smaller amount of soda produces more lift.
