Ingredients You’ll Need
The combination of mashed ripe banana, zucchini, plus dark chocolate will have you loving eating veggies for breakfast!
- Bananas: Ripe bananas to overripe. The uglier bananas, the sweeter the muffins. You can also use previously frozen bananas or here is how to ripen bananas fast.
- Zucchini: Shred on medium size hole grater and pack in the measuring cup. Do not squeeze.
- Dark chocolate bar: 100 grams or 3.5 oz dark chocolate bar. My kids loved banana zucchini muffins with 70% dark chocolate, I found them a bit too sweet and prefer unsweetened chocolate or 90% dark chocolate. You can use 1/2 cup chocolate chips, if preferred.
- Whole wheat or spelt flour: These are only 2 flours I would recommend to use because other flours act differently. Baking is a science and it is best to follow the recipe for favorable results.
- Maple syrup: Any liquid sweetener like honey, agave or brown rice syrup works. As long as it’s not sugar. Dry sweetener will offset the ratios and batter won’t work.
- Egg: Room temperature for best results.
- Oil: Any mild tasting oil works.
- Baking staples: Baking powder, baking soda, vanilla extract, and salt.
How to Make Healthy Banana Zucchini Muffins
Made in one bowl these healthy banana zucchini muffins couldn’t be easier to whip up!
Prep: Preheat oven to 375 degrees F and line muffin tin with parchment paper liners.
Chop the chocolate bar by running a chef’s knife through it on a cutting board. You want some small pieces but otherwise keep chocolate to larger chunks.
Also now it’s time to grate zucchini on a medium size hole of a box grater.
Make batter: In a large mixing bowl, lightly whisk the egg. Add bananas and mash well, using a masher or a fork.
Add grated zucchini, maple syrup, oil, vanilla extract, baking powder, baking soda and salt. Whisk to combine, you can also use same masher to stir the liquids. Now add flour and gently stir with spatula until well incorporated.
Last, add your reserved chopped chocolate and give a few more gentle stirs.
Fill muffin tin and bake: Fill tin almost full with batter. I like to use a trigger ice cream scoop as it distributes the batter evenly, quickly and without a waste.
Bake for 22 minutes or until a toothpick inserted in the centre comes out clean. Remember all ovens vary, so just check and play it by ear.
Then cool your healthy banana zucchini muffins for 5 minutes in the tin, then on a cooling rack for as long as you can resist. And enjoy!
- Make it egg free: Omit the egg and learn how to make a flax egg or chia egg for vegan banana zucchini muffins.
- Mini muffins: Set the time for 12 minutes, then test. If mini muffins are not done, add 3 minutes and so forth. Mini muffins can take anywhere from 15-18 minutes.
- Loaf: Reduce oven temp to 350F degrees and bake 50-60 minutes for a full sized 9×5 loaf or 25-30 minutes for miniature loaf.
- Oil free: You can try half oil and half applesauce to lower the amount of oil. This has only been reader tested. You may like these almond flour zucchini muffins which contain no oil.
- Yellow summer squash: Could be used instead of zucchini. Carrots could be tried, or make my healthy morning glory muffins instead.
- Swap berries for chocolate: I recommend fresh or frozen blueberries, or just make these healthy blueberry banana muffins.
Can I Substitute the Whole Wheat Flour?
Baking is a science and the only flours I tested in this healthy banana zucchini muffins recipe are whole wheat flour and spelt flour.
You may try to use all-purpose flour or gluten free flour blend with a total amount of 1 cup. You just need a tad less of it than of whole grain flour to avoid dry muffins.
I think you can get away with half whole wheat flour and half white flour, for sure.
White whole wheat and whole wheat pastry flour more likely will work 1:1 ratio. Please let me know if you try.
Coconut flour will not work as it is very “thirsty”. And almond flour is basically ground up almond and has no gluten, so it acts very differently too. Try my reader favorite almond flour banana muffins instead. Also these oat flour banana muffins are gluten free as well.
No. The skin of zucchini is thin and edible. Grating it on medium size hole makes zucchini barely noticeable. However, if selective eaters in your house turn their nose up at green flecks in their banana muffins with zucchini, by all means peel it and your zucchini becomes invisible.
Do not squeeze the water out of your zucchini for this muffin recipe! Shredded zucchini is what keeps these muffins moist. All recipes vary.
Yes! Just be sure to thaw them first and use the extra liquid as well. Got more bananas? Check out these 10 healthy banana snack recipes!
Previously grated and frozen, yes. Just thaw it a bit or completely and use the liquid as well.
How to Store
I like to store muffins covered with a towel on a kitchen counter for the first 2 days.
Since these are healthy banana zucchini muffins and contain minimal oil and natural sweetener, I transfer muffins to an airtight container and refrigerate for another 3 days.
Refrigeration helps muffins to retain moisture. If there are any leftovers, of course.
How to Freeze
Place cooled muffins in a gallon size Ziploc bag, let as much air as possible and freeze for up to 3 months. Mini quick breads take about 3 hours to thaw on a counter, muffins will thaw in less time.

These were a hit! I substituted some of the flour for protein pancake mix for a little extra protein and everyone had seconds. A win! How long will these stay on counter or in fridge?
Fantastic! Glad you enjoyed the recipe! There are full instructions on storage in the post.
Our favourite muffin recipe. Practically the only muffins we make now!
I’m so happy to read this! Thanks for your positive feedback!
These came out way too wet. Tried baking longer but no luck. Made it as the recipe, with spelt flour. Can you maybe provide a weight measurement for the zucchini? Or a picture what it’s supposed to look like when grated? I suspect mine was too fine and/or wet 🙁
Sorry to hear about that. Not sure why it happened, could be a few reasons. If your batter looked like in the photo, then muffins should turn out. Did you scoop and level flour? Did you make any recipe substitutions?
I had the same issue 🙁 any longer and the tops would be burnt, but the insides are still wet and soggy.
I have to say that must be an oven issue. Some ovens run hotter. In this case I would bake the muffins on a middle rack and reduce the oven temperature by 25° F.
