5 Best Baking Soda Substitutes for Waffles

Quick tip: Using baking powder can slightly increase the batter’s acidity and may yield a slightly softer texture but maintains good rise and flavor.

Baking powder contains both an acid and a base, allowing it to release carbon dioxide when moistened and heated, which leavens the waffle batter effectively. This makes it the most straightforward substitute for baking soda in waffles.

To ensure success, use about three times the amount of baking powder as baking soda, since baking powder is less concentrated. Avoid overmixing the batter to preserve the leavening gas bubbles.

Compared to baking soda, baking powder may produce waffles with a slightly different crumb structure—often a bit fluffier and less crisp—but overall the texture and rise remain very acceptable.

Quick tip: Potassium bicarbonate provides similar leavening without sodium, resulting in waffles with comparable texture and rise but a slightly different mineral taste.

Potassium bicarbonate is chemically similar to baking soda (sodium bicarbonate) and reacts with acids in the batter to produce carbon dioxide gas, which leavens waffles effectively.

When substituting, use it in a 1:1 ratio. Since potassium bicarbonate lacks sodium, it may taste slightly different, so balancing with a pinch of salt in the recipe can help.

The final waffles will have a similar rise and crumb to those made with baking soda, with minimal impact on texture or flavor when adjusted properly.

Quick tip: Incorporating whipped egg whites adds aeration and lightness but requires careful folding to avoid deflating the batter.

Whipped egg whites introduce physical leavening by trapping air bubbles, which expand during cooking to lighten the waffle texture. This method compensates for the lack of chemical leavening from baking soda.

For best results, separate eggs and whip the whites to soft peaks, then gently fold into the batter just before cooking. This requires more technique and may not fully replicate the rise from baking soda.

Waffles made this way tend to be lighter and airier but may lack the characteristic crispness and uniform rise baking soda provides.

Quick tip: Sourdough starter adds natural acidity and fermentation gases, contributing to leavening and flavor complexity but may alter waffle taste.

Sourdough starter contains wild yeast and lactic acid bacteria that ferment the batter, producing carbon dioxide and acids that react with any alkaline components to leaven waffles.

Using discard starter in place of baking soda introduces natural leavening but requires adjustments in liquid content and possibly resting time to allow fermentation.

The resulting waffles will have a tangier flavor and a denser crumb compared to baking soda waffles, with a unique texture that some may find desirable.

Quick tip: This combination mimics baking soda’s leavening but can slightly increase acidity, affecting flavor subtly.

Cream of tartar is an acid that can react with baking powder’s base to release carbon dioxide, providing leavening similar to baking soda’s acid-base reaction.

Mixing these in the stated ratio approximates the leavening power of baking soda, but care must be taken to balance acidity to avoid sourness.

Waffles made with this combo will rise well but may have a slightly tangier taste and softer texture compared to those with baking soda.
