Substitute for baking soda

Here’s how to substitute baking soda in recipes. The formula is using triple the quantity of baking powder to equal the same amount of baking soda.

1 teaspoon baking soda = 3 teaspoons of baking powder

Make sure that the baking powder is not past its use-by date. Keep in mind that adding triple the baking powder can sometimes add a little bitterness to baked goods. If at all possible, head to the store and grab that baking soda instead!

What is baking soda vs baking powder?

Here’s a really quick breakdown! Baking soda (sodium bicarbonate) and baking powder are both leaveners, which means they’re used to make baked goods rise. What’s the difference?

  • Baking soda is a base. When combined with an acid (lemon, buttermilk, vinegar, yogurt) in a recipe, it produces carbon dioxide bubbles and makes the baked good rise. It’s about 3-4x stronger than baking powder.
  • Baking powder is a mix of baking soda, plus an acid (like cream of tartar). Since it already has the acid, it doesn’t rely on acid in the recipe to provide lift to baked goods.

Frequently asked questions

What is baking soda, and what does it do?

Baking soda (sodium bicarbonate) is a chemical leavening agent that reacts with acids to produce carbon dioxide gas, causing baked goods to rise. It’s commonly used in recipes that also contain acidic ingredients like buttermilk, yogurt, or vinegar.

Will using a substitute affect the taste or texture of my baked goods?

Some substitutes may slightly alter the taste or texture of your baked goods. For example, using baking powder may result in a slightly more acidic flavor. Use the real thing if at all possible.
