Best Baking Powder Substitute in Bagels

5 tested options with exact ratios, science-backed explanations, and tips for success.

Quick Answer

The best substitute for Baking Powder in Bagels is Baking Soda combined with Cream of Tartar because this combination replicates the leavening action of baking powder by providing both an acid and a base, ensuring proper rise and texture in the dense bagel dough.

Detailed Guide: Each Baking Powder Substitute in Bagels

Baking Soda + Cream of Tartar (Best Option)

1/4 teaspoon baking soda + 1/2 teaspoon cream of tartar per 1 teaspoon baking powder
Vegan Gluten-Free Dairy-Free Fat-Free Nut-Free
Quick tip: This combination closely mimics baking powder’s leavening, maintaining bagel texture and rise without altering flavor significantly.

Baking powder is essentially a mix of baking soda (a base) and an acid, often cream of tartar, which react to produce carbon dioxide gas that leavens dough. By combining baking soda with cream of tartar, you recreate this acid-base reaction, enabling the bagel dough to rise properly during baking.

To ensure success, mix the baking soda and cream of tartar thoroughly before adding to the dough to achieve even leavening. Avoid adding extra acidic ingredients as this can cause excessive bubbling and off textures.

Compared to commercial baking powder, this substitute offers nearly identical leavening power and results in bagels with the expected chewiness and slight puff without a metallic or bitter aftertaste.

Buttermilk + Baking Soda

1/2 cup buttermilk + 1/4 teaspoon baking soda per 1 teaspoon baking powder (reduce other liquids accordingly)

Quick tip: Adds slight tanginess and moisture, which can enhance bagel flavor but may slightly soften the crust.

Buttermilk is acidic and reacts with baking soda to produce carbon dioxide gas, providing leavening similar to baking powder. The acidity also tenderizes the dough slightly, which can complement the dense texture of bagels.

When using this substitute, reduce other liquid ingredients to compensate for the added buttermilk to maintain dough consistency. Monitor dough hydration carefully to avoid overly soft dough that can affect bagel shaping.

The final bagels may have a subtle tang and a slightly softer crust compared to those made with baking powder, but the chew and rise remain acceptable.

Yogurt + Baking Soda

1/2 cup plain yogurt + 1/4 teaspoon baking soda per 1 teaspoon baking powder (reduce other liquids accordingly)
vegetarian Gluten-Free Nut-Free
Quick tip: Yogurt provides acidity and moisture but can impart a mild dairy flavor and slightly softer crumb.

Similar to buttermilk, yogurt’s acidity activates baking soda to produce leavening gas. The moisture content also helps hydrate the dough, which can be beneficial in bagel recipes.

Adjust liquid amounts downward to maintain dough firmness typical of bagels. Use plain, unsweetened yogurt to avoid unwanted flavors.

Bagels made with this substitute may have a slightly tangier taste and softer texture, which can deviate from the traditional dense and chewy bagel but remain palatable.

Potassium Bicarbonate + Cream of Tartar

1/4 teaspoon potassium bicarbonate + 1/2 teaspoon cream of tartar per 1 teaspoon baking powder
Vegan Gluten-Free Dairy-Free Fat-Free Nut-Free
Quick tip: Good for low-sodium diets, with similar leavening but may have a slightly different aftertaste.

Potassium bicarbonate functions similarly to baking soda but contains potassium instead of sodium, making it suitable for sodium-restricted diets. When combined with cream of tartar, it produces carbon dioxide gas for leavening.

Mix thoroughly and use in the same manner as baking soda and cream of tartar. Watch for subtle flavor differences, as potassium bicarbonate can impart a mild bitter note if overused.

The bagels will rise and have a texture close to those made with baking powder, though the flavor may be slightly altered.

Whipped Egg Whites

2 large egg whites whipped to soft peaks per 1 teaspoon baking powder

Quick tip: Adds lift and lightness but can change bagel texture and increase protein content.

Whipped egg whites incorporate air into the dough, providing mechanical leavening rather than chemical. This can help lighten the dense bagel dough somewhat.

Careful folding is required to maintain air bubbles. This method does not produce carbon dioxide and thus leavening is less consistent and less durable during boiling and baking.

Bagels made with this substitute may be lighter but less chewy and dense than traditional bagels, altering the classic texture significantly.

❌ What NOT to Use as a Baking Powder Substitute in Bagels

Yeast

Yeast is a poor substitute for baking powder in bagels because bagels rely on yeast for fermentation and structure, while baking powder provides immediate chemical leavening. Using yeast alone cannot replace the quick rise effect of baking powder, potentially resulting in denser, less tender bagels.

Self-Rising Flour

Self-rising flour is not ideal because it contains baking powder and salt in fixed amounts, which may disrupt the precise balance of ingredients in bagel dough. Bagels require tight control over leavening and salt for their characteristic chew and crust, so self-rising flour can cause inconsistent texture and flavor.

Baking Soda Alone

Baking soda alone is ineffective as a substitute because it requires an acid to activate. Bagel dough typically lacks sufficient acidic components to trigger baking soda's leavening, leading to poor rise and potential off-flavors.
