Preheat the oven to 350 degrees F ( 176 degrees C). Grease a bread loaf pan.
In a large bowl, blend the banana, applesauce, sugar, oil, and vanilla. Add the flour, baking powder, baking soda, salt, and cinnamon; mix just to combine. Stir in the peaches. Pour the batter halfway into the prepared bread pans.
Place them into the preheated oven and bake for about an hour. Check to see if it’s fully baked by placing a toothpick or fork into the middle of the loaf, if it comes out clean, it’s finished. If it has batter on it, bake for another 15 minutes.
