Why You’ll Love These Muffins
I have so many muffins and breads made with bananas, zucchini or a combination of both, I lost count! These healthy banana zucchini muffins is a recipe back from circa 2017 that I just re-tested.
It all started with perfecting my healthy banana zucchini bread, then healthy chocolate zucchini bread, then healthy zucchini bread and now no one can stop me!:)
What I like about these banana zucchini muffins is that there is no refined sugar (except a tiny bit in a dark chocolate bar), just a little bit of oil instead of 1 cup like in traditional recipes, plus they are filled with fruits and veggies. And made in one bowl!
Yes, this banana zucchini muffins recipe is a bit more heavy because of whole wheat flour but I give you a conversion for an all-purpose flour or you can use white whole wheat flour.
Ingredients for Healthy Banana Zucchini Muffins
- Bananas: Use ripe to overripe bananas. 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 of a box grater, pack in a measuring cup and then squeeze dry. No need to peel. You can also use yellow squash. Also can use previously grated and frozen zucchini, just thaw first, measure and squeeze.
- Flour: Whole wheat flour or spelt flour has been tested in this recipe. White whole wheat and whole wheat pastry flour more likely will work 1:1 ratio. I also give a conversion for an all-purpose flour in the recipe card below. I think you can get away with half whole wheat flour and half white flour, for sure.
- Maple syrup: I like the taste of maple syrup. Any liquid sweetener like honey, agave or brown rice syrup works. As long as it’s not dry sugar because it will offset the ratios in the batter.
- Egg: Acts as a binder. I think you can safely try to use a flax egg or chia egg instead.
- Oil: I actually like the taste of extra virgin olive oil in zucchini banana muffins. But avocado oil, melted coconut oil or melted butter are great contenders.
- Baking staples: Baking powder, baking soda, vanilla extract, and salt.
- Dark chocolate bar: 3.5 ounces dark chocolate bar. You can also use 1/2 cup of chocolate chips, if preferred.
How to Make Healthy Banana Zucchini Muffins
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, then squeeze the excess moisture well.
Make batter: In a large mixing bowl, add bananas and mash well, using a masher or a fork.
Add grated and dry zucchini shreds, an egg, maple syrup, oil, vanilla extract, baking powder, baking soda and salt. Whisk to combine. 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: Divide the batter. I like to use a trigger ice cream scoop as it distributes the batter evenly, quickly and without a waste.
Bake for 21 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!
Tips for Best Results
- Make sure of no white lumps: I am a strong believer in one bowl muffin batter if you mix baking powder and baking soda well. Make sure they are not lumpy before adding, and then just whisk well.
- Don’t overmix the batter: Especially when it comes to whole wheat flour, the more you mix, the more dense muffins will be because mixing activates the gluten in flour. Mix just enough.
- Measure flour correctly: Scoop and level the flour into the measuring cup with a spoon, then level with a knife at the top.
- Don’t overbake: Remove muffins from the oven as soon as toothpick inserted in the center comes out clean. Dry muffins are overbaked muffins.
Variations
- Mini muffins: Set the time for 12 minutes, then test. If mini muffins are not done, add 3 minutes and so forth.
- Additions: Add up to 1/3 cup of chopped walnuts or pecans, or coconut flakes.
- Swap berries for chocolate: I recommend fresh or frozen blueberries, or raisins.
How to Store
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.
Freeze: Place cooled muffins in a gallon size Ziploc bag, let as much air as possible and freeze for up to 3 months. Muffins take about 2 hours to thaw on a kitchen counter.
