2. In a small bowl, use a fork to finely mash bananas (I used 3). Set aside.
3. In a large bowl, sift flour, sugar, baking soda and salt together. Stir in brown sugar.
4. In another bowl, use a whisk to combine eggs, buttermilk (or sour cream), oil, applesauce and vanilla extract.
8. Bake bread for about 1 hour. Check the done-ness of your bread by sticking a toothpick or knife into the center. It should come out clean. If it isn't, leave the bread in for more time.
Recipe updated February 2024: Includes tiny edits I have used for the last 10 years. Recipe no longer includes 1 tsp. lemon juice and has the option of using buttermilk or sour cream.
