I took my Mom’s Banana Bread recipe and turned it into an EASY Zucchini Banana Bread – this recipe was SO good and simple and it disappeared fast! The cinnamon sugar topping is a game changer – and it made this bread out of this world!

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!

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. The natural sweetness of the banana adds nice moisture and flavor to the bread, and the zucchini loosens up the batter because it’s wet when grated. It’s the perfect zucchini bread!

Ingredients & Substitutions

  • BANANAS: I like to use really overripe “tired” bananas. Did you know that when your ripe bananas get spotty you can freeze them? They turn brown, slimy and gross looking, but they work amazing in baked banana recipes. Just defrost before adding to the batter.
  • MILK: My mom’s recipe calls for sour milk. Since that’s not a thing anymore, I use regular milk and add vinegar to the batter. You can also use lemon juice. You can also use any kind of milk (dairy or nondairy milk).
  • 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.
  • ZUCCHINI: Shred your zucchini with a box grater. No need to ring it out unless it seems unusually wet or has been thawed from frozen. A medium zucchini is perfect.
  • EXTRAS: I add cinnamon sugar on top the bread, which can be optional. You can also fold in 1/2 cup chopped walnuts or pecans. You could also add chocolate chips.

How to make Zucchini Banana Bread

  1. Add the oil to a large bowl with granulated sugar, mashed banana, 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.
  2. 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.
  3. Bake until a toothpick comes out clean from the center of the bread.

Storage

Store bread covered with plastic wrap on the counter or freeze it tightly wrapped for several months.

FAQ

Why do you use sour milk/buttermilk?

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.

Do you squeeze water out of zucchini for bread?

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.

Why did my zucchini bread collapse?

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.

Recipe Notes

  • In place of vegetable oil you can also use 1/2 cup softened unsalted butter.
  • You can use dairy-free milk (i.e. almond milk) 
  • If you have lots of overripe bananas you can freeze them in their peels. When ready to bake, just thaw however many you need. The peels will be brown and the banana will be wet and (honestly) kind of unappetizing looking, but it will bake up just fine!
  • Store in an airtight container or bag on the counter for a few days. You can also freeze banana bread (whole or slices) wrapped well in plastic wrap.
