Running out of baking soda while making banana bread can be frustrating, but there are some simple substitutes you can use to get that perfect rise. One of the easiest alternatives is baking powder. If your recipe calls for 1 teaspoon of baking soda, just use 3 teaspoons of baking powder instead.
Another great option is to incorporate buttermilk or yogurt into your batter. Both of these ingredients provide moisture and the acidity needed for leavening. If you choose this route, remember to slightly reduce the other liquid ingredients in your recipe. A helpful guideline is to replace 1 teaspoon of baking soda with about 1 cup of buttermilk or yogurt, adjusting the other liquids as necessary.
Finally, if you have cream of tartar on hand, you can mix it with baking powder to create a baking soda substitute. For every teaspoon of baking soda, combine 2 teaspoons of cream of tartar with 1 teaspoon of baking powder. This will help keep your banana bread light and fluffy without needing to run to the store.
