Banana Zucchini Olive Bread
There's something deeply comforting about a loaf that tastes like cake but bakes like bread-this Banana Zucchini Olive Bread is that magical hybrid. Home cooks adore it because it turns two humble ingredients, bananas and zucchini, into a treat so moist and flavorful that no one would guess it's secretly wholesome. Perfect for lazy weekend breakfasts, afternoon tea with friends, or a lunchbox surprise, this bread stays fresh longer than most and improves with a quick toast. The olive oil adds a subtle richness, while the walnuts and chocolate deliver just the right crunch and indulgence.
What Makes This Recipe Special
- Olive oil replaces butter, lending a fruity, slightly peppery note that elevates the banana and zucchini flavors without heaviness.
- Grated zucchini is pressed lightly to remove excess moisture before folding in, ensuring a tender crumb and preventing a soggy loaf.
- Dark chocolate chips and walnuts are folded in at the end to preserve their texture and prevent sinking during baking.
- A touch of almond milk balances the richness of the olive oil and ensures a smooth, pourable batter without over-mixing.

Instructions
1
Preheat your oven to 175°C (350°F) and grease or line a loaf pan with parchment paper.
2
In a large mixing bowl, mash the bananas until smooth. Add grated zucchinis, sugar, olive oil, almond milk, and vanilla extract. Stir until fully combined.
3
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and a pinch of salt.
4
Gradually fold the dry ingredients into the wet ingredients until just combined. Avoid overmixing. If using add-ins, fold in the dark chocolate chips and/or chopped walnuts.
5
Pour the batter into the prepared loaf pan, spreading evenly. Bake for about 60 minutes, or until a toothpick inserted into the center comes out clean.
6
Allow the banana zucchini bread to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Slice and serve.
Essential Tips
Press zucchini dry
After grating, place zucchini in a clean kitchen towel and squeeze firmly to remove excess water. This prevents a gummy texture and helps the loaf bake evenly and rise properly.
Use very ripe bananas
Look for bananas with plenty of brown spots-they're sweeter and mash more easily, contributing deeper flavor and natural sugar without needing extra sweetness.
Don't overmix the batter
Fold dry ingredients in just until no flour streaks remain. Overmixing develops gluten, resulting in a tough, dense loaf instead of a tender crumb.
Add-ins at the end
Fold chocolate chips and walnuts in the last step to keep them visible and prevent them from sinking to the bottom during baking.
Check bake early
Start checking doneness at 50 minutes with a toothpick. The loaf can over-brown on top even if the center is still slightly wet due to the moist ingredients.
Smart Swaps & Variations
Vegan Banana Zucchini Bread
Replace almond milk with oat milk and use vegan chocolate chips. Ensure chocolate is dairy-free and use flax egg (1 tbsp ground flax + 3 tbsp water per egg) if avoiding eggs.
Nut-free version
Omit walnuts and add ½ cup sunflower seeds or pumpkin seeds for crunch and healthy fats.
Lower sugar
Reduce sugar to ⅓ cup (65g) and add 1 tsp cinnamon to enhance sweetness naturally.
Whole grain boost
Swap half the all-purpose flour for white whole wheat flour or oat flour for added fiber and nuttiness.
Spiced twist
Add ½ tsp ground cinnamon and ¼ tsp nutmeg to the dry ingredients for a warm, autumnal flavor.
What to Serve With This
- Warm slices with a schmear of whipped cream cheese or mascarpone and a drizzle of honey.
- A cup of strong brewed coffee or a latte, perfect for weekend brunches or afternoon pick-me-ups.
- A dollop of Greek yogurt and fresh berries for a light, protein-rich breakfast.
- Packed in lunchboxes with a thermos of chai tea for a satisfying mid-day treat.
Storage & Reheating
Storage
Wrap cooled loaf tightly in plastic wrap or store in an airtight container at room temperature for up to 4 days. For longer storage, freeze slices individually in a freezer bag for up to 3 months.
Reheating
Toast slices directly from frozen or thaw overnight in the fridge. Warm in a toaster or toaster oven to restore moisture and crispness-avoid the microwave, which can make the loaf gummy.
Expert Chef Tips
- Toast walnuts lightly before folding in to deepen their flavor and prevent raw bitterness.
- Use a microplane to zest half a lemon into the batter for a bright, citrusy lift that cuts through the richness.
- Bake in a 9x5-inch pan, not larger-this ensures the loaf is tall enough to slice evenly and develop a good crust on top.
Equipment You’ll Need
- 9x5-inch loaf pan
- Box grater (for zucchini)
- Large mixing bowls (2)
- Kitchen towel or cheesecloth (for pressing zucchini)

Frequently Asked Questions
Can I use coconut oil instead of olive oil?
Yes, use refined coconut oil for a neutral flavor. Melt it first, then cool slightly before mixing. It adds a subtle tropical note and keeps the loaf moist for days.
Why is my loaf dense or gummy in the middle?
This usually happens if the zucchini wasn't pressed dry or if the batter was overmixed. It can also occur if the oven temperature is too low. Always use a reliable oven thermometer.
Can I make this in a bundt pan or muffin tin?
Yes! Bake bundt-style for 50-55 minutes or muffins for 18-22 minutes. Reduce sugar slightly if using a bundt pan to avoid burning edges. Check early.
What's the best way to grate zucchini without it getting watery?
Use the large holes of a box grater and press firmly in a clean towel. Alternatively, salt grated zucchini, let sit 10 minutes, then squeeze again-this removes even more moisture.
Can I omit the chocolate chips?
Absolutely-swap in raisins, dried cranberries, or chopped dried apricots for a fruity alternative. The loaf will still be moist and tender.
How do I know when it's fully baked?
Insert a toothpick into the center-it should come out clean or with a few moist crumbs. The internal temperature should reach 95°C (203°F) when measured with an instant-read thermometer.
Can I add orange zest or spices like cardamom?
Yes! Add 1 tbsp orange zest or ½ tsp cardamom to the dry ingredients for a bright or aromatic twist. These complement the banana and zucchini beautifully.
Why does this bread taste better the next day?
The flavors meld and deepen overnight as the sugars and oils distribute evenly. The texture also firms up slightly, making it easier to slice cleanly.
