⭐ Baking Soda and Cream of Tartar (Best Gluten-Free Option)
1/4 teaspoon baking soda + 1/2 teaspoon cream of tartar per 1 teaspoon baking powderBaking powder is essentially a mixture of baking soda (a base) and an acid (often cream of tartar). When combined with moisture and heat, they produce carbon dioxide gas that leavens the bread. Using baking soda and cream of tartar separately replicates this reaction precisely.
To ensure success, mix the two powders thoroughly before adding to the batter to avoid uneven rising. Avoid overmixing the batter after adding to preserve the gas bubbles.
The final quick bread will have a similar rise, crumb, and flavor profile compared to using commercial baking powder, making this the closest and most reliable substitute.
