Why this is the BEST Zucchini Banana Bread
If you’ve ever wondered can bananas be put in zucchini bread or can zucchini be put in banana bread, then this is the recipe for you!
Regardless of whether you have a garden or not, you can make this easy banana bread with zucchini!
Cinnamon sugar zucchini banana bread is so easy to make and delicious to eat!
I started this recipe with my mom’s banana bread recipe and combined the idea of zucchini with my cinnamon sugar blueberry banana bread recipe. I love quick bread recipes – I have so many on this site and love each and every one.
It was easy to switch my normal banana bread recipe to a zucchini banana bread: all I needed to do was reduce the banana and add shredded zucchini. This results in a delightfully tasteful banana bread with a hint of zucchini. The zucchini is a vegetable which makes this bread a vegetable, yes?
Ingredients in Zucchini Banana Bread
- BANANAS: I like to use really overripe “tired” bananas. Did you know that when your bananas get spotty you can freeze them? I cleaned out my freezer the other day and found about 2 dozen frozen bananas. They turn brown, slimy and gross looking, but they work amazing in baked banana recipes. Just defrost before adding to the batter.
- SOUR MILK: I love using sour milk in my banana bread. This just means you need to add some vinegar to your milk beforehand, to make it “sour”. You can also use buttermilk instead, or if you can even use almond, coconut, or soy milk. In that case, just add vinegar to the mixture to help activate the baking soda.
- SUGAR: I prefer granulated sugar, just like my mom uses.
- OIL: I love making quick bread with vegetable oil – it makes it so easy to mix up. You can also substitute melted butter.
- FLOUR: This recipe uses all-purpose flour but you can use a combination of AP and whole wheat flour.
- BAKING SODA: This is the leavened in the recipe – it’s activated by the sourness of the milk.
- ZUCCHINI: Shred your zucchini with a box grater. No need to ring it out unless it seems unusually wet.
How to make Zucchini Banana Bread
- Add the oil (or melted butter) to a large bowl with granulated sugar, eggs, and vanilla extract. Stir until smooth.
- Add baking soda, cinnamon, salt, milk, and vinegar and stir until batter is combined.
- Stir in shredded zucchini.
- Add to a 9×5-inch loaf pan (or an 8×4-inch) and top with cinnamon sugar. The cinnamon sugar topping – that’s the best part. It gets crunchy in the oven and adds so much delicious flavor to the top of the bread.
- Bake until a toothpick comes out clean from the center of the bread.
Tip From Dorothy
- Zucchini shreds easiest using a box grater. You’ll need 1 large or 2 small for this recipe.
- If you have an abundant amount of zucchini you can freeze the shreds – or make extra zucchini bread with chocolate chips or even blueberry zucchini bread.
- You can skip the cinnamon sugar topping but don’t – it’s SO good!
- Zucchini Banana Bread is done when a toothpick comes out clean from the center of the loaf.
The sourness of the milk (the acid in the buttermilk) activates the baking soda, helping the bread to rise. If you don’t have buttermilk make your own by adding vinegar or lemon juice to milk.
Yes, you can substitute any non-dairy milk, but you need to add 1 tsp vinegar or lemon juice to activate the baking soda.
I never have to, it seems that the zucchini isn’t too wet. But if yours seems wetter then normal, then go ahead, it won’t hurt.
You may have over mixed it or mixed too vigorously. Is it baked all the way? If you didn’t bake it all the way it will collapse as it’s cooling.
Do the toothpick test in the center of the bread. It should come out with just a few crumbs stuck to it when it’s done.
Yes! Add 1 cup of either to the bread before it goes into the pan.
Yes – I’ve had success substituting Bob’s Red Mill one to one gluten free AP flour (in the light blue bag).
