Easy Banana Zucchini Chocolate Chip Muffins made with sweet bananas and fresh summer zucchini make a delicious quick breakfast, afternoon snack, or addition to packed lunches!

*I updated this post with new photos and an improved layout for a better user experience. This is the original recipe. 😊
If you ask my kids, the best part of zucchini season is all the yummy baked goods you can make with it, haha!
These muffins are like banana bread muffins made with zucchini, if that makes sense. You really can't taste the zucchini- trust me!
What sets this recipe apart from other zucchini muffin recipes is that it's made with whole-grain flour, mashed bananas (for natural sweetness), and less added sugar.
And, as for the chocolate chips - they are a make-it-or-break-it if for muffins made with zucchini and bananas. Sort of like when you make bliss balls or sheet pan cookies. Just saying. 💁♀️

Why You'll Love This Recipe

Dietitian Tips
Tip 1 Muffins are a great way to help you eat more whole grains, fruit AND veggies, especially on busy mornings!
Tip 2 While these muffins do contain fiber, they are not high in protein. For this reason, I either serve them with a baked egg, glass of milk, or yogurt to help balance out the meal or snack.
Ingredient Notes
Notes on a few key ingredients for making these delicious muffins:
- Zucchini Adds fiber, vitamins (like vitamin C, vitamin B-6, and folate), and minerals (like potassium and manganese).
- Bananas Bananas are full of fiber and potassium. They also serve as a fabulous sweetener, especially over-ripe bananas.
- Flour Golden Wheat Flour (white whole wheat flour) and oat flour are used to provide the perfect consistency and flavor. Both are made from whole grains, which means they are excellent sources of fiber. Can use all-purpose flour instead.
- Chocolate Chips Use semi-sweet or dark chocolate chips. Reserve some of the chocolate chips so you can place them on top of the filled muffin cups before baking.

Helpful Tips
- Do not overmix the batter.

- Use either use a fork or a kitchen utensil like a hand-held meat or potato masher to mash the over-ripe bananas. It's easy!
- Shred the zucchini as you would shred a block of cheese. I use a box grater. A food processor or mandolin would work as well. Just be sure to wash the zucchini and trim both ends off first
- If using freshly grated zucchini, you do not need to ring it out first.
- Once cooled, store muffins in airtight container at room temperature for up to three days.
- Refrigerate or freeze muffins you don't anticipate eating within 3 days.
- For mini muffins, reduce the baking time.
Questions You May Have
While I haven't tried it myself, this recipe should work if you replace all of the flour with a 1:1 gluten-free flour substitute.
Make your own oat flour by blending rolled oats in a blender or food processor. I did this when I made the muffins pictured in this post because I had run out of store-bought oat flour.
Oat flour softens these muffins that would otherwise be a little denser if made with white whole wheat flour alone.
While I haven't tried it, you should be able to substitute milk with water or a dairy-free milk alternative. The consistency will be a little different, but it should still work.
If you make these muffins dairy-free, please let me know how they turn out!
Yep! To turn this into a quick bread, pour the batter into a loaf pan, reduce the baking temperature to 325 degrees, and increase the baking time to about one hour.

Really good, easy to make, I used half coconut oil and half olive oil, honey instead of sugar and I did not have oat flour so I used spelt flour. Great way to use up my banana stash and those ever present zucchini .
