The recipe calls for walnuts but did not specify an amount. I substituted 1/4 cup flax seed and it work out well. Also, depending on the size of the bananas used, the mixture may come out too thin. I used large bananas and that was the case. I just added more bran to get the proper consistency. Perfect muffins for the church function, left overs went to work where they disappeard in an hour, with people asking for the recipe.
Mixed and kneeded in the Kitchen Aide with a dough hook for 10 minutes. Texture came out great. Not a large second rise in the bread pan, but the finished texture was right for a heavier bread and the taste was great. I am going to try adding gluten next time to see if the rise is better.
