Got overripe bananas sitting on the counter and zucchini taking over the garden? This banana zucchini bread solves both problems at once — and it's the best quick bread I've ever made. I've been making it on repeat every summer since I developed it, and it earns requests every single time.
This zucchini banana bread recipe is moist, warmly spiced, and made with a blend of whole wheat and all-purpose flour for extra fiber and staying power. The bananas add natural sweetness and incredible moisture, the zucchini melts into the batter leaving only gorgeous green flecks, and the result is a loaf that stays tender for days. It's a genuinely fun baking project — my toddler loves helping mash the bananas — and one that works just as well for breakfast as it does for an afternoon snack.

Zucchini + Banana = 😍
Most quick bread recipes solve one overripe or abundant produce problem. This one solves two.
Overripe bananas are the backbone of every great banana bread — the spottier the better. They mash easily, add natural sweetness that reduces the need for added sugar, and create a moist, tender crumb that regular bananas simply can't replicate.
Garden zucchini is the secret weapon. It adds moisture and body to the batter, keeps the loaf tender for days longer than a traditional banana bread, and melts into the crumb—leaving only tiny green flecks and no zucchini flavor. It's the hidden vegetable win that makes this feel slightly more virtuous than regular banana bread.
Together, they create a loaf that's more moist, more flavorful, and more interesting than either ingredient alone.
The Banana Guide
The ripeness of your bananas makes or breaks this recipe.
|
How Ripe is Ripe Enough? |
Very ripe. Look for bananas that are deeply spotted or mostly black. The more spotted, the sweeter and more flavorful. Under-ripe bananas make dense, not-as-sweet bread. |
|
How to Quickly Ripen Bananas |
Place unpeeled bananas on a baking sheet and bake at 300°F for 15–20 minutes until the skins turn black and the flesh is soft. Cool before mashing. |
|
Can I use Frozen Bananas? |
Yes, as long as they were overripe when frozen. Thaw completely and drain the excess liquid before mashing. |
|
How Many Bananas |
2 large overripe bananas (or 1 cup mashed) |
How to Prep the Zucchini
Getting this right makes the loaf tender and moist, not gummy:
- Do you need to squeeze zucchini for banana bread? Not for standard medium zucchini—the butter-rich batter handles moisture well. If you're working with very large, end-of-season zucchini that seem unusually watery, a light squeeze in a clean kitchen towel adds extra insurance. You don't need to wring it dry — just a gentle press.
- How to shred: Use the large holes of a box grater. No peeling needed — the skin is thin and melts into the batter, leaving only pretty green flecks. A food processor with a shredding attachment works too for faster prep.
- How much zucchini: 1¼ cups shredded or about 1 medium zucchini.
The Whole Grain Difference
This banana zucchini bread uses a blend of all-purpose and whole wheat flour — and it's worth talking about why.
All-purpose flour keeps the texture light and tender. Whole wheat flour adds fiber, a slightly nutty depth of flavor, and keeps you full longer (it's almost never a bad thing to add a touch of wholesomeness, I figure!) The combination gives you the best of both: a moist, tender crumb with more nutritional value than a straight white-flour loaf.
- Can you use all whole wheat flour? Yes, the loaf will be slightly denser but still delicious, with more fiber and a heartier texture. For a lighter texture, use all whole wheat pastry flour.
- Can you use just all-purpose flour? Yep, the loaf will be lighter and slightly less nutritious, but still 100% delish. Use 2¾ cups (330g) total.
More Important Ingredients and Substitutions
Unsalted butter — Softened to room temperature, not melted. Creaming softened butter with the sugar creates a light, tender crumb. For dairy-free, use ½ cup softened virgin coconut oil or vegan butter in its place.
Greek yogurt — Adds moisture and tenderness. Full-fat gives the richest result. For dairy-free, use ⅓ cup mayonnaise (avocado oil, olive oil, or light mayo all work).
Brown sugar — Packed light or dark. Dark brown sugar adds a deeper molasses note. Don't swap all white sugar — the moisture content matters for texture.
Allspice — The subtle warm spice alongside cinnamon that gives this loaf its depth and classic zucchini bread flavor. Use just ¼ teaspoon, and don't skip it.
Recipe Variations
This banana zucchini bread recipe is wonderful as written, but you're always welcome to make it your own:
- Chocolate Chip — Fold in ½ cup mini chocolate chips before pouring the batter into the pan. An extra touch of decadence for the whole family!
- Walnut or Pecan — Fold in ½ cup of chopped walnuts or pecans for crunch and a classic banana bread feel.
- Double Chocolate — Substitute ¼ cup of flour with unsweetened cocoa powder and add ½ cup of chocolate chips.
- Cream Cheese Swirl — Beat 4 oz. softened cream cheese with 2 tablespoons sugar, then swirl it into the top of the batter before baking.
- Muffin Version — Scoop batter into lined muffin cups using ½-cup scoops, and bake at 350°F for 22–26 minutes. For a slightly more wholesome variation, check out my Banana Zucchini Muffins recipe.
- Gluten-Free — Substitute a 1:1 GF flour blend for both flours (2¾ cups / 330g total), let the batter rest at room temperature for 30 minutes before baking, and cool it entirely before enjoying.
How to Make Zucchini Banana Bread
For the complete recipe and measurements, scroll to the recipe card at the bottom of this post.
Prepare: Preheat the oven to 350°F. Grease an 8x4-inch loaf pan with nonstick spray or butter.
Step 1: In a large mixing bowl with a hand mixer or stand mixer, cream the softened butter, brown sugar, and granulated sugar together until smooth and creamy, scraping down the sides as needed.
Step 2: Beat in the eggs until smooth and light yellow in color.
Step 3: Beat in the Greek yogurt, vanilla extract, and mashed bananas until combined. The batter may look slightly curdled — that's normal.
Step 4: In a separate bowl, whisk together the all-purpose flour, whole wheat flour, baking soda, salt, cinnamon, and allspice.
Step 5: Slowly beat the flour mixture into the butter mixture until the streaks of flour just disappear.
Step 6: Add the shredded zucchini and gently beat on low until just combined.
Step 7: Pour the batter into the prepared loaf pan. Bake 1 hour 10 minutes to 1 hour 25 minutes until a toothpick or knife inserted in the center comes out clean. Start checking at 1 hour 10 minutes.
Step 8: Cool on a wire rack until completely at room temperature before slicing.
Chelsea's Recipe Pro-Tips
- Use very ripe bananas — Heavily spotted or mostly black bananas are sweeter, mash more easily, and make a more flavorful, moist loaf. Under-ripe bananas result in a denser, less sweet bread.
- Large or watery zucchini? — Give it a light squeeze in a kitchen towel before adding. Standard medium zucchini goes straight in — no squeezing needed.
- Don't overmix — Once the flour goes in, beat until the streaks just disappear. Overmixing develops gluten and makes the loaf dense and tough.
- The batter will look curdled — When you add the bananas to the creamed butter mixture, the batter looks a bit broken. It's fine. It comes together once the flour goes in.
- Cool completely before slicing — The crumb needs time to set. Slicing warm leads to a gummy, compressed texture.
- Tent with foil if browning too fast — If the top is getting dark before the center is done, tent loosely with aluminum foil for the remainder of the bake time.
Storage Directions
- Storing: Keep covered at room temperature for 2–3 days, or refrigerate in an airtight container for 4–5 days.
- Freezing: Cool completely, then freeze whole or pre-sliced in a freezer-safe bag for up to 2–3 months. Pre-sliced is the move for easy grab-and-go breakfasts — thaw individual slices at room temperature for 30–60 minutes or microwave for 20–30 seconds.
Serving Suggestions
This banana zucchini bread is the kind of loaf that disappears fast. It's equally perect for a quick weekday breakfast or a weekend baking treat. Serve a warm slice with a Protein Coffee for a satisfying start to a busy day, or pair it with Scrambled Eggs with Cottage Cheese for a balanced, protein-forward breakfast that keeps everyone full.
Banana Zucchini Bread Recipe FAQs
Very ripe — deeply spotted or mostly black. The riper the banana, the sweeter and more flavorful the bread. Under-ripe bananas make a denser, less flavorful loaf. If your bananas aren't ripe enough, bake them unpeeled at 300°F for 15–20 minutes until the skins turn black.
Not for standard medium zucchini — the butter-rich batter handles the moisture well without squeezing. If you're working with very large, end-of-season zucchini that seem unusually watery, a light squeeze in a clean kitchen towel adds extra insurance.
Most likely caused by a very large or watery zucchini, underbaking, or too much flour from scooping directly from the bag. For oversized zucchini, a light squeeze in a kitchen towel before adding helps. Always weigh or spoon-and-level the flour, and test doneness with a toothpick in the very center — it should come out clean.
Yes — freeze for up to 2–3 months. Cool completely first, then wrap tightly or freeze pre-sliced for grab-and-go convenience. Thaw at room temperature or microwave a slice for 20–30 seconds.
Yes — fold ½ cup of mini chocolate chips into the batter before baking.
Yes — scoop batter into lined muffin cups using ½-cup scoops, and bake at 350°F for 24–26 minutes, until a toothpick comes out clean.
A toothpick or knife inserted in the very center should come out completely clean. The top should be deep golden brown and spring back slightly when pressed. Start checking at 1 hour 10 minutes — ovens vary and this loaf can take up to 1 hour 25 minutes.
Yes, as long as they were overripe when frozen. Thaw completely and drain the excess liquid before mashing.

Banana Zucchini Bread (Moist, Wholesome & 10 Min Prep Time!)
Ingredients
- ½ cup unsalted butter softened to room temperature
- ½ cup packed brown sugar light or dark
- ½ cup granulated sugar
- 2 large eggs
- ⅓ cup plain Greek yogurt 2%, 4% or full-fat
- 1 teaspoon pure vanilla extract
- 1 cup mashed bananas from about 2 large overripe bananas

- 1 ¼ cup (155g) whole wheat flour
- 1 teaspoon baking soda
- ¼ teaspoon salt
- 2 teaspoons ground cinnamon
- ¼ teaspoon allspice
- 1 ¼ cup shredded zucchini unpeeled
Instructions
- Preheat oven to 350°F. Grease an 8x4-inch loaf pan with nonstick spray or butter.
- In a large bowl with a hand mixer or stand mixer, cream the butter, brown sugar, and granulated sugar until smooth and creamy. Scrape down sides as needed.
- Beat in the eggs until smooth and light yellow in color.
- Beat in the Greek yogurt, vanilla extract, and mashed bananas until combined. Batter may look slightly curdled — that's normal.
- In a separate bowl, whisk together the all-purpose flour, whole wheat flour, baking soda, salt, cinnamon, and allspice.

Notes
- Weigh the flour —all-purpose: 190g, whole wheat: 155g. Or spoon into cup and level off the top. Never scoop directly from the bag; it can add up to 30% more flour, which makes the loaf dense and heavy.
- Squeezing zucchini — not needed for standard medium zucchini. For very large or watery zucchini, a light squeeze in a kitchen towel adds extra insurance.
- Curdled batter — normal when bananas meet creamed butter. It comes together with the flour.
- Tent with foil — if the top browns too fast before the center is done, tent loosely with aluminum foil for the remainder of the bake time.
- Gluten-free — use 2¾ cups (330g) of a 1:1 GF flour blend.
- Dairy-free — use ½ cup virgin coconut oil or vegan butter instead of butter and ⅓ cup mayonnaise instead of Greek yogurt.
- Chocolate chips — fold in ½ cup, tossed in 1 tablespoon flour to prevent sinking.
- Muffins — scoop ½ cup batter into lined muffin cups; bake at 350°F for 24–26 minutes.
- Chocolate chips — fold in ½ cup mini chocolate chips before baking.
- Storage — room temperature for 2–3 days, refrigerate in an airtight container for 4–5 days, freeze for up to 2–3 months.
