This Easy Zucchini Banana Bread is light and fluffy, courtesy of whipped egg whites folded into the batter. It’s an old fashioned recipe that’s perfect with a cup of coffee or tea.
Moist and rich, with mashed ripe bananas and flecks of fresh zucchini, this Easy Zucchini Banana Bread recipe is seriously GOOD!
It’s the perfect mash-up of zucchini bread and banana bread. And, it uses a special technique to get a soft and fluffy loaf: the addition of beaten egg whites, stirred into the batter right before baking.
It’s quick bread at its finest, and it’s delightful as a quick breakfast or easy afternoon snack.
It’s also a great way to enjoy the abundance of summer zucchini in July and August. My Chocolate Chip Zucchini Cake is another way!

- Make sure that the zucchini is wrung out well before adding it to the batter. More tips on that below!
- When whipping the egg whites, make sure there are no yolks in the bowl. If there is any trace of the yolks, the whites won’t whip up like they should.
- You can easily double this recipe to make 2 loaves. Click the “2X” on the recipe card to get the exact amounts.
- You’ll need 2 ripe bananas (ones with brown spots are perfect) and 2 small zucchini. You can substitute 1 medium to large sized zucchini instead.
- A little bit of sour cream makes this loaf extra moist. You can also substitute Greek yogurt.
- We’ll use both baking powder and baking soda for leavening.
- All of the other ingredients are your baking standards: flour, sugar, butter, eggs, vanilla, and salt.
How to make Easy Zucchini Banana Bread
Most quick breads are easy recipes, requiring just a bowl and a spoon. Since we’ll be whipping egg whites, we’ll use a stand mixer to make this recipe extra easy. You can also use a hand mixer.
Start by grating the zucchini. I used a box grater. Place the zucchini in a colander and press on it with a spatula to release the liquid from the zucchini.
Next, place 2 egg whites in the bowl of a stand mixer. Make sure there are NO egg yolks in there, since the whites won’t whip up if there are yolks.
Whip the egg whites until light and fluffy.
Place the egg whites in another bowl.
In the now-empty stand mixer bowl (no need to clean it out), place the butter and sugar. Cream the butter and sugar together until light and fluffy.
Add the egg yolks, sour cream, vanilla, bananas, and grated zucchini. Mix until combined.
There’s no need to mash the banana before adding it, because the mixer will do it for you.
Add the flour, baking powder, baking soda, salt, and cinnamon. Mix just until combined, taking care not to over mix it.
Finally, fold in the beaten egg whites with a spatula. This addition will make the loaf light and fluffy instead of overly dense.
Bake the zucchini banana bread for 50–60 minutes at 350°F, or until a toothpick comes out clean.
Let the loaf cool for at least 10 minutes before removing from the pan.
Can I make zucchini banana bread ahead of time?
This easy Zucchini Banana Bread is perfect for making ahead. You can bake this loaf up to 48 hours in advance of serving it. Wrap it tightly in foil and store at room temperature.
Can I freeze zucchini banana bread?
To freeze, wrap the loaf in aluminum foil and place in a resealable freezer bag. Freeze for up to 2 months.
Defrost at room temperature overnight.
Frequently Asked Questions

2) Wring it out in a clean kitchen towel
