Question: how to replace baking soda in banana bread?
Answer: Baking powder is a great substitute for baking soda in banana bread. 1/4 teaspoon baking soda = 1 teaspoon baking powder. I adapted this recipe from my ever so popular banana bread recipe for 2 bananas and all I did was replace the 1 teaspoon of baking soda with 4 teaspoons of baking powder.
