Healthy Zucchini Banana Bread is the best way to use up fresh zucchini and over ripe bananas. Moistened and sweetened with fruit and veggies, you can't even tell zucchini is there!
Preheat oven to 350 degrees F and line 9" x 5" loaf pan with parchment paper or spray with cooking spray. Set aside.
In a large bowl, mash bananas with a fork. Add zucchini, egg, oil, maple syrup, vanilla extract, cinnamon, baking powder, baking soda and salt. Whisk well - sometimes if baking soda and baking powder have lumps, it takes a minute to let them sit and then whisk again.
Add flour and stir with spatula just until combined.
Transfer batter into prepared loaf pan, level with spatula and bake for 50-60 minutes or until toothpick inserted in the middle comes out clean.
Remove from the oven, let cool in a loaf pan for 10 minutes and then transfer onto the cooling rack to cool more. Cut with serrated knife into 12 slices and enjoy.
Notes
Update June 2025: I have retested the recipe in June 2025 for better results as per reader's feedback.
Store: If you are baking bread in summer, I highly recommend to refrigerate it in a container lined with double paper towel. During cooler months, store covered on a counter for 3-4 days.
Freeze: Past day 4, I recommend to freeze bread. Place in Ziploc bag and freeze for up to 3 months. Thaw on a counter for a few hours.
Use very ripe bananas: The more yellow with more brown spots your bananas are, the sweeter the bread will be.
