Baking Soda Substitutes – 5 Best Leavening Options
The best substitute for baking soda is Baking Powder at a 1 tsp baking soda = 3 tsp baking powder ratio. It works best for cookies, quick breads, muffins. There are 4 other alternatives below, each with exact ratios and usage notes.
Best Substitute
Baking Powder
1 tsp baking soda = 3 tsp baking powder
Baking powder already contains an acid, so no additional acid is needed. Use 3x the amount but note that it may affect taste if too much is used.
Flavor & Texture Change
Slightly less browning and spread in cookies. Baked goods may taste very faintly different because baking soda alkalinity helps browning and flavor development.
When Not to Use
You need 3x as much baking powder as baking soda. This adds extra ingredients (cream of tartar, cornstarch) to your recipe, which can affect texture in delicate recipes. Too much baking powder creates a bitter, metallic taste.
Which Baking Soda Substitute Should You Use?
Best Overall
Baking Powder
Use 3x the amount of baking powder (1 tbsp baking powder per 1 tsp baking soda). Most universal substitute.
Best for Sensitive Diets
Potassium Bicarbonate
Sodium-free alternative that works identically to baking soda. Found in health food stores.
Best for Cookies
Baking Powder
Cookies will still brown and spread, just slightly less than with baking soda. Triple the amount.
Best for Flatbreads
Whipped Egg Whites
Mechanical leavening that works without any chemical agents. Fold into batter for lift.
What are the other substitutes for baking soda?
Potassium Bicarbonate
1 tsp baking soda = 1 tsp potassium bicarbonate
A 1:1 sodium-free substitute. Doesn't contain sodium, making it ideal for low-sodium diets. May need to add salt separately.
Flavor/texture:Virtually identical to baking soda. No flavor difference in the final product. Leavening power is the same.
Avoid when:Works 1:1 but does not contain sodium, so you may need to add a pinch of salt to your recipe. Less commonly available. Check health food stores or order online.
Baker's Ammonia (Ammonium Carbonate)
1 tsp baking soda = 1 tsp baker's ammonia
Traditional leavener for thin, crisp baked goods. The ammonia smell bakes off completely. Only use in flat, thin items.
Flavor/texture:Creates exceptionally crispy, light textures. The ammonia smell disappears completely in thin baked goods. Traditional leavener for European cookies and crackers.
Avoid when:Produces a strong ammonia smell during baking that must fully dissipate. Only use for thin, crispy items (crackers, cookies) where gas can escape completely. Never use in thick cakes or breads.
Self-Rising Flour (replace regular flour)
Replace all-purpose flour with self-rising flour, omit baking soda and salt
Self-rising flour contains leavening and salt already. Omit baking soda, baking powder, and salt from the recipe.
Flavor/texture:No flavor difference. Provides similar leavening to baking soda + baking powder combined.
Avoid when:Only works if the recipe also uses flour. You are replacing both the flour and the baking soda. Reduce salt in the recipe since self-rising flour contains salt.
Whipped Egg Whites
Fold 2-3 stiffly beaten egg whites into the batter
Provides lift through trapped air rather than chemical reaction. Works best in lighter batters. Fold gently to maintain volume.
Flavor/texture:No chemical leavening flavors. Creates a lighter, airier texture but without the characteristic chewy/crispy contrast that baking soda gives cookies.
Avoid when:Only provides mechanical lift, not the chemical browning and flavor that baking soda provides. Cookies will not spread or brown the same way. Fold gently to preserve the air bubbles.
What should you know before substituting baking soda?
Baking soda reacts immediately when combined with acid, so get batters into the oven quickly. It also promotes browning in cookies and pretzels. Never use more than specified-excess baking soda creates a soapy, metallic taste.
How do you substitute baking soda in a recipe?
Sodium bicarbonate, a leavening agent that reacts with acids to produce carbon dioxide gas, causing baked goods to rise. Also used for browning and tenderizing.
The best substitute for baking soda depends on what role it plays in your recipe. Our top recommendation is Baking Powder (1 tsp baking soda = 3 tsp baking powder), which works well for cookies, quick breads, muffins.
If you need a different option, Potassium Bicarbonate (1 tsp baking soda = 1 tsp potassium bicarbonate) is another reliable choice. A 1:1 sodium-free substitute. Doesn't contain sodium, making it ideal for low-sodium diets. May need to add salt separately.
When substituting baking soda, consider the flavor profile, texture, and cooking method of your recipe. For vegan alternatives, look for the options marked with the vegan badge above.

What can you use instead of baking soda in specific recipes?
Frequently Asked Questions
Can I use baking powder instead of baking soda?
Yes, use 3 times the amount of baking powder (3 tsp baking powder per 1 tsp baking soda). The results may be slightly different in texture and taste with large amounts.
What happens if I leave out baking soda?
Without baking soda, baked goods won't rise properly and will be dense and flat. Baking soda also promotes browning, so items may be paler without it.
Is baking soda the same as baking powder?
No. Baking soda is pure sodium bicarbonate and needs an acid (like buttermilk or vinegar) to activate. Baking powder contains baking soda plus its own acid and works in any batter.
