This zucchini banana bread combines shredded zucchini and mashed ripe bananas in one moist, lightly spiced loaf that tastes sweet without hiding a hint of vegetable.
The zucchini disappears into the crumb and adds moisture, while cinnamon gives the loaf a warm background flavor. You only need two bowls, a box grater, and about fifteen minutes of active work.

Why This Zucchini Banana Bread Recipe Works
Zucchini is mostly water, so it keeps the loaf moist for days without extra oil, and its mild flavor lets the bananas and cinnamon stay in front.
Two ripe bananas add natural sweetness and structure, which means you can use a modest amount of sugar and still get a loaf that tastes rich.
Vegetable oil coats the flour better than butter in a loaf this wet, so the crumb stays tender and slices cleanly even after a night on the counter.
Ingredients for Zucchini Banana Bread
- 2 ripe bananas, mashed
- 1 small zucchini, shredded and pressed dry
- 180 g all purpose flour, about one and a half cups
- 1 cup sugar
- 2 large eggs
- 1/2 cup vegetable oil
- 1 teaspoon baking soda
- 1 teaspoon cinnamon
- 1/4 teaspoon salt
Bananas. Use fruit with brown freckled peels. Riper bananas mash smoother, taste sweeter, and bake into a loaf that stays soft instead of turning dry.
Zucchini. Shred a small zucchini on the large holes of a box grater and skip peeling. The green flecks add color and the skin softens fully while baking.
Sugar. White sugar gives a clean sweetness, while brown sugar adds a slight molasses note and a softer crumb. Either one works in the same amount.
Vegetable oil. Neutral oil keeps the crumb moist. Melted coconut oil works too, though it can add a faint coconut flavor to the finished loaf.
Cinnamon. One teaspoon gives a gentle warmth. Skip it if you prefer a plain loaf, or add a pinch of nutmeg for a deeper spice note.
How to Make Zucchini Banana Bread
1. Heat the oven Heat the oven to 350 degrees F and grease a 9 by 5 inch loaf pan, or line it with parchment paper for easy removal later.
2. Prep the produce Mash the bananas in a large bowl. Shred the zucchini, then press it between paper towels to remove extra moisture so the loaf does not turn gummy.
3. Mix the wet ingredients Stir the zucchini, sugar, oil, and eggs into the mashed bananas until the mixture looks even and the sugar begins to dissolve.
4. Whisk the dry ingredients In a second bowl, whisk the flour, baking soda, cinnamon, and salt so the leavening and spice spread evenly through the flour.
5. Combine gently Add the dry mixture to the wet mixture in two parts and fold just until combined. Pour the batter into the pan and smooth the top.
6. Bake and cool Bake for about 60 minutes, until a toothpick comes out clean. Cool in the pan for ten minutes, then turn the loaf onto a wire rack.
How to Serve Zucchini Banana Bread
Serve thick slices plain or with a little butter. The loaf suits a breakfast table beside bacon and cheese crustless quiche and a cold glass of fresh pineapple lemonade. For an afternoon spread, add sheet pan apple crisp or a dish of baked cottage cheese eggs.
How to Store and Reheat Zucchini Banana Bread
Wrap the cooled loaf in foil or keep it in an airtight container at room temperature for up to three days. The moist crumb also freezes well, so wrap slices in plastic wrap and foil and freeze them for two to three months.
Tips and Variations for Zucchini Banana Bread
Dry the zucchini. Squeeze the shredded zucchini in paper towels until it stops releasing liquid. Extra water makes the center heavy and can leave a gummy streak near the bottom.
Skip the peeling. Zucchini skin is thin and tender, so leave it on. It adds color and saves a step without changing the texture of the baked loaf.
Stop mixing early. Fold the dry ingredients in just until combined. A few flour streaks will disappear as the batter rests, and extra stirring makes the loaf tough.
Add optional extras. Fold in chocolate chips, chopped walnuts, or blueberries for a different texture, and add a pinch of nutmeg if you want more spice.
Use a toothpick. Ovens vary, so check the center at 55 minutes. Keep baking in five minute steps if the toothpick comes out with wet batter.
Flag the allergens. The loaf contains wheat and egg, and walnuts are a tree nut, so label the loaf clearly and check every ingredient before serving guests.
Skip the raw batter. Do not taste the batter, because it contains raw egg and uncooked flour, and both can carry bacteria that cause illness.
Check trusted guidance. For general information on keeping food safe at home, read the Texas AgriLife Extension food safety guide.
