Baking Soda Substitute – What you use instead That Actually Works
Ever been halfway through baking cookies only to realize—you’re out of baking soda? Don’t worry, you’re not alone. Baking soda (also known as sodium bicarbonate) is one of those staple ingredients that always runs out right when you need it most.
After testing dozens of baking recipes and substitutes, I’ve learned what really works when you run out of baking soda—and what definitely doesn’t.
This guide covers the baking soda alternatives , how they work in different recipes, and the science behind why they do (or don’t) deliver the same rise and texture.
Whether you’re making pancakes, cookies, or quick breads, here’s everything you need to know about finding a reliable baking soda substitute for your next recipe.
What Is Baking Soda and What to Use Instead of Baking Soda in Baking ?
Before you start swapping, Let’s first understand what baking soda actually does.
Understanding how a baking soda substitute works can save your recipe from falling flat. Since baking soda (or bicarbonate of soda) is a crucial leavening agent, finding the right substitute for baking soda that replicates its chemical reaction is essential for perfect rise and texture.
Baking soda is a leavening agent
Baking soda is a leavening agent—a base that reacts with acidic ingredients like vinegar, lemon juice, or buttermilk to release carbon dioxide gas. This gas helps your batter expand, making baked goods light and fluffy.
Without baking soda
Without baking soda, your baked goods can turn out dense, flat, or unevenly browned. That’s why choosing the right substitute for baking soda matters—some replacements can mimic that rise, while others simply can’t.
Baking soda = rise + browning + texture.
In short: Baking soda = rise + browning + texture.
If you remove it, you must replace it with something that can react in a similar way.
Best Baking Soda Substitutes (with Measurements)
Here are 10 of the most effective and tested baking soda substitutes, including how to use them, when to avoid them, and what recipes they work best in.
The best baking soda substitutes and baking soda alternatives vary based on your recipe, but these tested options have you covered for bicarbonate soda substitute.
1. Baking Powder (The Most Common baking soda substitutes)
If you’re out of baking soda, baking powder is your best friend.
It actually contains both an acid and a base, which means it can leaven on its own.
Ratio:
Use 3 teaspoons of baking powder for every 1 teaspoon of baking soda.
When it works best: Pancakes, muffins, and cakes.
Pro Insight: Baking powder won’t make cookies as crisp as baking soda does—it gives a softer, cake-like texture.
Keyword tip: “Can I substitute baking powder for baking soda?” — Yes, but you’ll need more of it and may notice a milder taste.
2. Potassium Bicarbonate (Sodium-Free Option)
If you’re cutting sodium or following a low-salt diet, potassium bicarbonate is a nearly identical substitute for baking soda—without the sodium.
Ratio:
➡️ Use a 1:1 substitution for baking soda.
Pro Insight: Add a pinch of salt to balance flavor, since potassium bicarbonate doesn’t include any.
Works well in: Bread, muffins, and pancakes.
3. Self-Rising Flour | Bicarbonate of Soda Substitute Option
Self-rising flour is another sneaky way to replace baking soda. It already contains baking powder and salt, so it can lift your baked goods naturally.
Ratio:
➡️ Replace 1 cup of all-purpose flour + 1 tsp baking soda with 1 cup of self-rising flour.
When it works best: Biscuits, scones, and quick breads.
Quick Tip: Skip any extra salt in your recipe if using self-rising flour—it’s already included.
4. Whipped Egg Whites
For a completely natural baking soda substitute in baking, look no further than whipped egg whites. They trap air and add lift to cakes and soufflés.
Ratio:
➡️ Replace 1 teaspoon of baking soda with 2 whipped egg whites (soft peaks).
Pro Insight: Works best in recipes that already call for eggs—like sponge cakes or waffles.
5. Club Soda
Believe it or not, club soda contains carbon dioxide (CO₂) and a touch of baking soda, making it a surprisingly good substitute for baking soda in pancakes and cakes.
Ratio:
➡️ Replace any liquid portion in your recipe with the same amount of club soda.
When it works best: Pancakes, waffles, and light batters.
Pro Insight: Use it right before baking—the fizz fades quickly!
6. Baker’s Ammonia (Ammonium Carbonate) | Best Alternative for Baking Soda in Cookies and Cakes
This old-fashioned ingredient was used before modern baking powder. It produces carbon dioxide when heated.
Ratio:
➡️ Use ½ teaspoon baker’s ammonia for 1 teaspoon baking soda.
Pro Insight: Best for thin, crisp cookies—not suitable for cakes (strong smell when raw).
7. Yeast
Though not a direct chemical substitute, yeast can provide the lift needed in some recipes like bread or rolls.
Ratio:
➡️ Replace 1 teaspoon of baking soda with 1 packet (7g) of dry yeast, activated in warm water.
Pro Insight: Only suitable for yeast-based or bread-like recipes—skip it for cookies or cakes.
8. Lemon Juice + Baking Powder Combo
If you have baking powder but want extra lift, add a dash of lemon juice to activate it even more.
Ratio:
➡️ Mix 2 tsp baking powder + ½ tsp lemon juice per 1 tsp baking soda.
When it works best: Muffins, banana bread, and chocolate cakes.
9. Vinegar + Baking Powder
Vinegar (especially white or apple cider) can mimic the acidic reaction baking soda provides when mixed with baking powder.
Ratio:
➡️ Use 2 tsp baking powder + ½ tsp vinegar for 1 tsp baking soda.
Pro Insight: Great for chocolate cakes—vinegar enhances the cocoa flavor.
10. Plain Yogurt or Buttermilk
Both plain yogurt and buttermilk contain lactic acid, which naturally reacts with other leavening agents.
Ratio:
➡️ Replace 1 tsp baking soda with ¼ cup yogurt or buttermilk (and reduce other liquids accordingly).
Quick Tip: This adds moisture and tang—ideal for muffins or pancakes.

When to Avoid baking soda substitutes
Not every recipe tolerates substitution.
Here’s when to skip it:
- Crisp cookies: Substitutes often make them too soft.
- Recipes relying heavily on browning: Baking soda aids caramelization.
- High-acid recipes: Overdoing the acid can make the batter collapse.
Rule of thumb: If baking soda is more than ½ tsp per cup of flour, choose a strong chemical substitute (like baking powder or potassium bicarbonate) rather than a natural one.
Why Use a Baking Soda Substitute?
Many recipes call for baking soda as a leavening agent to help baked goods rise, brown, and develop texture. But sometimes you’re out of baking soda or need a different option due to dietary restrictions or flavor preferences. Knowing the right substitute for baking soda can help you continue baking without compromising your results. Whether you’re looking for a baking soda alternative for cookies, cakes, bread, or pancakes, the right substitute will react with your recipe’s acids and provide similar lift and flavor.
How to Substitute Baking Soda for Baking Powder (and Vice Versa)
These two ingredients often confuse even experienced bakers.
Here’s the difference:
- Baking soda = pure sodium bicarbonate (needs acid).
- Baking powder = sodium bicarbonate + dry acid + cornstarch.
To substitute baking soda for baking powder:
➡️ Use ⅓ tsp baking soda + 1 tsp vinegar or lemon juice for 1 tsp baking powder.
To substitute baking powder for baking soda:
➡️ Use 3 tsp baking powder for 1 tsp baking soda.
Pro Insight: Adjust the recipe’s salt and acid levels to balance flavor.
