Preheat your oven to 350
Add your bananas to a mixing bowl and mash
Add in your shredded zucchini, milk, vanilla, egg, and applesauce and mix until everything is combined
Add in your flour, baking powder, baking soda, cinnamon, and salt and mix until just combined (do not over mix)
Add your mixture to your mini muffin trays, I filled to the top for bigger muffins
Bake for 12-15 minutes until a toothpick inserted in the center comes out clean
Let cook in the mini muffin tray for 5 minutes then move to a cooling rack to cool completely
Serve and enjoy!
