We measured out what we thought was enough baking soda, then realized halfway through the bowl was nearly empty. Baking soda provides the alkaline lift that reacts with acids in batters and doughs, creating the bubbles that make cakes rise and cookies spread.
The right substitute depends on what the recipe needs-some swaps triple the volume, others change the liquid balance. Start with the closest match for your dish, then adjust liquid or acidity if the swap requires it.
| # | Substitute | Best For | Ratio | Key Note |
|---|---|---|---|---|
| 1 | Baking Powder | 🥧 Baking | 3:1 | Milder rise, slightly acidic |
| 2 | Potassium Bicarbonate | 🥧 Baking | 1:1 | Low-sodium option |
| 3 | Club Soda | ✨ Both | ½ cup per tsp | Reduce other liquids |
| 4 | Self-Rising Flour | 🥧 Baking | 1 cup flour mix | Contains salt and powder |
| 5 | Sourdough Starter | 🥧 Baking | ¼ cup per tsp | Tangy, adjust liquids |
| 6 | Whipped Egg Whites | 🥧 Baking | 2 whites per tsp | Airy, neutral flavor |
| 7 | Baking Ammonia | 🥧 Baking | 1:1 | Crisp cookies only |
| 8 | Arrowroot & Cream of Tartar | 🥧 Baking | ¼ teaspoon + ½ tsp | Gluten-free option |
| 9 | Vinegar & Baking Powder | 🥧 Baking | 1 teaspoon + ½ tsp | Adds tanginess |
Baking powder and potassium bicarbonate are top substitutes matching leavening and alkalinity. Focus on matching rise and acidity balance first. Adjust liquids slightly when using baking powder for best texture in sweet baking.
9 Easy Baking Soda Swaps for Cooking
Some swaps stay close to the original alkalinity, while others require small adjustments to liquid or acidity. Pick based on what you have and what the recipe demands-baking needs precision, but quick breads and batters forgive more.

1 - Baking Powder
Baking powder contains both an acid and a base, so it reacts without needing acidic ingredients like buttermilk or vinegar. The pan matters for texture and crust, so common Baking Powder swaps ranked keeps you in the right range for even leavening.
Use three teaspoons of baking powder for every teaspoon of baking soda the recipe calls for. The rise is gentler and the crumb slightly finer.
- Triple the volume - More powder needed to match the lift.
- No extra acid - Works in recipes without buttermilk or lemon juice.
- Slightly tangy - Adds a faint acidic note to the finished bake.
- Lower alkalinity - Less browning on crusts and cookies.
Skip if: the recipe already includes baking powder or needs strong browning.
Baking Powder
Works for: Cakes, muffins, and recipes without strong acids
Skip if: You want deep browning or crisp edges
Baking Soda
Works for: Recipes with buttermilk, vinegar, or citrus
Skip if: There's no acid to activate the rise
2 - Potassium Bicarbonate
Potassium bicarbonate behaves almost identically to baking soda but contains zero sodium. The alkalinity is the same, so browning and rise happen at the same rate.
Swap it in equal amounts-one teaspoon of potassium bicarbonate for one teaspoon of baking soda. If you're managing sodium intake, this is the cleanest match.
Skip if: potassium restrictions apply or you prefer the subtle flavor salt brings to baked goods.
3 - Club Soda
Club soda adds carbonation directly to batters, which creates lift as the bubbles expand in the oven. The swap depends on what Club Soda substitutes for cooking can do for quick breads and waffles.
Use half a cup of club soda for every teaspoon of baking soda, and reduce the other liquids in the recipe by the same amount. The texture stays light but the rise is less predictable than chemical leaveners.
- Reduce liquids - Cut milk or water by half a cup.
- Use immediately - Carbonation fades fast once mixed.
- Best for batters - Works in pancakes, waffles, and quick breads.
- Mild mineral taste - Some brands add salt or potassium.
Skip if: the recipe needs a dry leavening agent or you want consistent rise across multiple batches.
4 - Self-Rising Flour
Self-rising flour contains all-purpose flour, baking powder, and salt mixed in. It's built for cakes and biscuits where you want a balanced rise without measuring multiple leaveners.
Results vary by dish, so Self-rising Flour alternatives worth trying helps when texture and structure matter most.
Replace one cup of all-purpose flour plus one-quarter teaspoon of baking soda with one cup of self-rising flour. Reduce or skip any additional salt the recipe calls for, since the flour already includes it.
- Built-in leavening - No need to add baking powder separately.
- Adjust salt - The flour contains about half a teaspoon per cup.
- Softer crumb - Lower protein than bread flour, so biscuits and cakes stay tender.
Skip if: the recipe needs precise flour control or you're making yeast breads.
| Use | Ratio | Notes |
|---|---|---|
| Biscuits | 1:1 for AP flour + soda | Reduce salt by half |
| Quick breads | 1:1 for AP flour + soda | Skip extra baking powder |
| Pancakes | 1:1 for AP flour + soda | Watch for over-salting |
5 - Sourdough Starter (discard)
Sourdough discard adds natural acidity and fermentation, which reacts with other ingredients to create lift. The tangy flavor comes through, so it works best in breads and pancakes where that note fits.
Use one-quarter cup of sourdough starter for every teaspoon of baking soda, and reduce the liquid in the recipe by the same amount. The rise is moderate and the texture stays moist.
Skip if: you want a neutral flavor or the recipe doesn't call for fermented ingredients.
6 - Whipped Egg Whites
Whipped egg whites trap air, which expands in the oven to create lift. The method works best in light cakes and soufflés where structure comes from foam rather than chemical leaveners.
If you're short on egg whites too, White Pepper replacements that work covers the closest backup plan for airy textures.
Use two egg whites, whipped to stiff peaks, for every teaspoon of baking soda. Fold them in gently at the end to avoid deflating the foam.
What to expect:
- Delicate rise - Depends on how well the whites hold air.
- Neutral flavor - No chemical or acidic taste.
Skip if: the batter is too dense or the recipe needs a reliable chemical rise.
7 - Baking Ammonia (Ammonium Carbonate)
Baking ammonia delivers a strong rise and produces the crispest texture of any leavener. It's used in traditional European cookies and crackers where moisture evaporates completely during baking, leaving no ammonia scent behind.
Swap it one-to-one with baking soda. The ammonia smell is strong while baking but disappears once the cookies cool.
Here's what to know:
- Crisp cookies only - Moisture traps the ammonia smell, so avoid thick cakes.
- Strong odor - Ventilate the kitchen while baking.
Skip if: the baked good is thick, moist, or stored in an airtight container before fully cooling.
8 - Arrowroot Powder plus Cream of Tartar
Arrowroot powder is a neutral starch, while cream of tartar provides the acidity needed to activate the rise. Each substitute behaves differently, so Arrowroot Powder replacements that work narrows it to options that match gluten-free baking needs.
Mix one-quarter teaspoon of arrowroot powder with one-half teaspoon of cream of tartar to replace one teaspoon of baking soda. The combination works best in recipes where a mild rise is enough.
Skip if: the recipe needs strong alkalinity or you want maximum browning.
9 - Vinegar & Baking Powder
Combining vinegar and baking powder mimics the acid-base reaction that baking soda creates naturally. The tang from the vinegar comes through, so it fits best in recipes where a slight sourness works-quick breads, cakes with chocolate, or anything with fruit.
Different pans distribute heat differently, so if you're out of baking powder too, swaps when Baking Powder runs out helps you match the rise.
Use one teaspoon of baking powder plus one-half teaspoon of vinegar for every teaspoon of baking soda. Add the vinegar with the wet ingredients and mix quickly-the reaction starts immediately.
- Mix fast - Bubbles form as soon as vinegar meets baking powder.
- Tangy finish - White vinegar adds less flavor than apple cider.
Skip if: the recipe is sensitive to vinegar taste or you need a neutral rise.
Before You Swap Baking Soda
Most of these swaps work without major recipe changes, but the best choice depends on what you're making. For cakes and muffins, baking powder or potassium bicarbonate stay closest to the original.
For crisp cookies, baking ammonia delivers the best texture.
- Closest match - Potassium bicarbonate for identical alkalinity
- Easiest grab - Baking powder in triple the amount
- Dietary option - Arrowroot and cream of tartar for gluten-free baking
Frequently Asked Questions
Yes, but use three teaspoons of baking powder for every teaspoon of baking soda. The cookies will spread less and brown more lightly, so expect a softer, cakier texture.
Too much baking soda leaves a bitter, soapy taste. Stick to the recipe's amount, and make sure there's enough acid to neutralize the alkalinity-buttermilk, vinegar, or citrus all work.
Yes. Baking soda helps beans soften faster and creates crispier fried coatings. Use a pinch in bean-soaking water or mix it with flour for fried chicken batter.
The batter won't rise as much, and the texture will be denser. Cookies spread less, cakes sink in the center, and quick breads turn heavy.
Most people tolerate it fine, but those with kidney issues or potassium restrictions should check with a doctor before using it regularly in place of baking soda.
