The best substitutes depend on what you're making
Baking soda and baking powder are not the same thing, and which one you need depends on what's in your recipe. If a recipe calls for baking soda, you're looking for something that reacts with an acid (buttermilk, lemon juice, vinegar, brown sugar) to create lift. If it calls for baking powder, you need something that works on its own or with heat. Swapping them without understanding the difference will change how your baked good rises, tastes, and feels.
For cleaning, baking soda works because it's mildly abrasive and slightly alkaline. Some replacements work the same way; others work through different chemistry. The right choice depends on what you're cleaning and what you have on hand.
Key Takeaways
- Baking powder can replace baking soda in most baked goods, but use three times as much because it's less concentrated.
- For recipes that rely on acid (buttermilk, yogurt, vinegar, lemon juice), potassium bicarbonate works like baking soda but tastes slightly different.
- Cleaning with salt, cream of tartar, or white vinegar works for different surfaces—salt for scrubbing, vinegar for dissolving mineral deposits, cream of tartar for delicate items.
- Self-rising flour contains baking powder already mixed in, so it can replace both flour and leavening in some recipes.
- Club soda creates carbonation that can lift batters, but it works best in recipes where you want a light, airy texture like pancakes or waffles.
Baking powder as a direct swap in most recipes
Baking powder is the easiest replacement because it already contains baking soda plus an acid (usually cream of tartar) and a filler. If your recipe calls for 1 teaspoon of baking soda, use 3 teaspoons (1 tablespoon) of baking powder instead. The extra amount compensates for the fact that baking powder is less concentrated.
This works in almost any recipe—cakes, cookies, quick breads, muffins. The main drawback is that baking powder can leave a slightly metallic or bitter taste if you use too much, especially in recipes where that flavor would be noticeable. Chocolate cakes and brownies usually mask it; delicate vanilla or lemon cakes sometimes don't. If you're making something where taste matters most, taste a small test batch first.
Double-acting baking powder (the most common kind in grocery stores) releases some gas when wet and more when heated, so it gives you a wider window to get your batter into the oven without losing lift.
Potassium bicarbonate for acid-based recipes
If your recipe specifically relies on an acid—buttermilk, sour cream, yogurt, vinegar, lemon juice, or brown sugar—potassium bicarbonate is the closest chemical match to baking soda. It reacts the same way and produces the same carbon dioxide lift. Use it in a 1:1 ratio (if the recipe calls for 1 teaspoon baking soda, use 1 teaspoon potassium bicarbonate).
The catch is that potassium bicarbonate is harder to find than baking soda or baking powder. Health food stores, specialty baking suppliers, and online retailers carry it. It's sometimes labeled as a salt substitute because it contains potassium instead of sodium. If you use it, check the label to make sure you're buying pure potassium bicarbonate, not a blend with other salts.
The flavor is nearly identical to baking soda, so there's no taste difference in the finished product.
Self-rising flour when you can adjust the recipe
Self-rising flour has baking powder and salt already mixed into the flour. If you're making biscuits, pancakes, or quick breads, you can use self-rising flour and skip the separate baking soda or baking powder entirely. For every 1 cup of regular flour in your recipe, use 1 cup of self-rising flour and reduce the salt by about 1/2 teaspoon (since the flour already contains it).
This works best when the recipe is straightforward and doesn't depend on a specific acid reaction. Recipes that call for buttermilk or vinegar can still work, but you'll need to reduce the salt more carefully because the acid will react with the baking powder that's already in the flour. If you're new to this swap, stick to recipes that were written for self-rising flour from the start.
Self-rising flour is widely available and costs about the same as regular flour, so it's a practical option if you bake frequently.
Club soda and carbonated water for light, airy batters
Club soda (carbonated water with added minerals) can replace baking soda in recipes where you want a light, bubbly texture—pancakes, waffles, tempura batter, or fritters. The carbonation creates tiny bubbles that make the finished product fluffy. Use club soda as a 1:1 replacement for any liquid in the recipe (milk, water, buttermilk).
This method works best when you use the batter right away, before the carbonation escapes. If you let the batter sit for more than a few minutes, you'll lose the lift. It also doesn't work well in dense batters or recipes that need a chemical reaction to rise properly—stick to recipes where you're aiming for texture rather than structure.
Plain carbonated water works the same way as club soda. The mineral content in club soda is so small that it won't change the flavor or texture of your baked good.
Cleaning surfaces without baking soda
For scrubbing surfaces, table salt or kosher salt works like baking soda because it's abrasive and won't scratch most materials. Mix salt with a little water to make a paste, explore it to the surface, and scrub with a damp cloth or sponge. This works well on stovetops, tile, and the inside of ovens. Rinse thoroughly with water afterward to remove all the salt.
For dissolving mineral deposits (hard water stains, soap scum), white vinegar is more effective than baking soda. Spray it on, let it sit for 15 to 30 minutes, and wipe clean. Vinegar is acidic, so it breaks down the mineral buildup that baking soda can't touch. Avoid using vinegar on natural stone (marble, granite) because the acid can etch the surface.
Cream of tartar mixed with lemon juice makes a gentle paste for delicate surfaces like stainless steel or chrome. It's less abrasive than salt and less acidic than vinegar alone, so it's safer for finishes that scratch easily. Mix equal parts cream of tartar and lemon juice, explore, let sit for a few minutes, and wipe clean.
When to use each replacement
| What you're making | Best replacement | Why |
|---|---|---|
| Cakes, cookies, muffins (no acid in recipe) | Baking powder (3x the amount) | Works on its own without needing an acid |
| Recipes with buttermilk, yogurt, or vinegar | Potassium bicarbonate (1:1 ratio) | Reacts with acid the same way baking soda does |
| Pancakes, waffles, tempura | Club soda (1:1 for any liquid) | Carbonation creates lift and lightness |
| Biscuits, quick breads | Self-rising flour (1:1 for flour) | Already contains leavening; reduce salt |
| Scrubbing stovetops, tile, ovens | Salt paste | Abrasive without scratching |
| Removing hard water stains, soap scum | White vinegar | Acid dissolves mineral deposits |
| Cleaning delicate finishes | Cream of tartar + lemon juice | Gentle abrasive, less acidic than vinegar alone |
Frequently Asked Questions
Can I use baking powder instead of baking soda in a recipe with buttermilk?
Yes, but you'll get a different result. Baking powder will work on its own, but the buttermilk won't react with it the way it does with baking soda. Use 3 teaspoons of baking powder for every 1 teaspoon of baking soda called for. The texture will be slightly different—usually a bit less tender—but it will still rise and bake.
What if I use baking soda when the recipe calls for baking powder?
The baked good will likely be dense and flat because baking soda needs an acid to set up, and most recipes that call for baking powder don't have one. If you must swap, use 1/3 teaspoon of baking soda for every 1 teaspoon of baking powder, and add 1/2 teaspoon of vinegar or lemon juice to the wet ingredients to trigger the reaction.
Is cream of tartar the same as baking powder?
No. Cream of tartar is one ingredient in baking powder, but it's not a leavening agent on its own. It's mainly used in cleaning or to stabilize egg whites. For baking, use baking powder or potassium bicarbonate instead.
Can I clean my oven with vinegar instead of baking soda?
Vinegar alone won't scrub away baked-on food, but it works well for dissolving grease and mineral deposits. For heavy buildup, make a paste with baking powder or salt first to scrub, then spray vinegar to dissolve what's left. Rinse thoroughly with water.
Does club soda work in all baking recipes?
No. It works best in recipes where you want a light, airy texture and where the batter is used right away. Dense cakes, cookies, and recipes that need chemical leavening to rise properly won't work well with club soda alone. Use it for pancakes, waffles, and fried batters.
