Grease one 9x5-inch loaf pan (or spray sides and bottom of loaf pan).
In the bowl of you mixer, cream together the butter and sugar until light and fluffy; add eggs and mix until blended. Stir in the mashed bananas and the sourdough starter. Stir in the vanilla extract or orange zest; set aside.
In another bowl, combine the flour, baking powder, baking soda, cinnamon, nutmeg, and salt.
Add the flour mixture, chopped nuts, and shredded zucchini squash to the prepared sourdough mixture, stirring just until blended.
Pour batter into prepared loaf pan and let the filled loaf pan aside for 15 to 20 minutes before baking. This is not your usual sourdough bread recipe where you let the dough rise until doubled. You only let it rest for approximately 20 minutes.
Preheat oven to 350 degrees F. Adjust oven rack to middle position.
Bake approximately 60 to 65 minutes (it took me 65 minutes to achieve the proper temperature) or until a toothpick inserted in the center comes out clean. Be sure and poke the toothpick already to the center of the loaf.A good check is to use an instant digital thermometer to test your bread. The internal temperature of the bread should be at 200 degrees F. when done.
This is the type of cooking and meat thermometer that I prefer and use in my cooking. I get many readers asking what cooking/meat thermometer that I prefer and use in my cooking and baking. I, personally, use the Thermapen Thermometer shown in the photo on the right. To learn more about this excellent thermometer and to also purchase one (if you desire), just click on the underlined: Thermapen Thermometer.
Remove from oven and cool on a wire rack 10 minutes; remove from pan. Cool completely before slicing.
Storage: Breads that contain fruit, nuts, or butter may be stored for 2 or 3 days, well wrapped in plastic wrap or aluminum foil. May be frozen for longer storage. After thawing frozen breads, reheat them in a 400 degree F. oven for a few minutes before serving.

Ultimate Banana Bread
This recipe for banana bread fascinated me, as it takes 6 bananas in the recipe. Also the bananas are heated, juiced, and the juice reduced! I had never heard of this technique before, so I just had to give it a try. I very slightly adapted a few instructions in the recipe from the Cooks Illustrated Magazine, America's Test Kitchen, Season 11.
