Combine flour, baking soda, baking powder, and walnuts in a bowl. Stir gently until well blended
In another bowl, combine aquafaba, oil, yogurt, vanilla extract, sugar, and brown sugar. Mix until blended.
Add the mashed bananas and blend.
Slowly mix in the flour mixture.
Pour mixture into a greased loaf pan.
Bake until golden brown and check that a toothpick inserted into the center comes out clean (about an hour).
Allow to sit in the pan for about 10 minutes, then turn out onto a rack to cool.
Notes
I skipped the salt in this recipe because there was salt in the beans. If you use salt free bean brine you can add a ½ teaspoon sea salt if you'd like.
