Table of Contents

There’s something comforting about a loaf that smells like home. This banana zucchini cake recipe brings together the natural sweetness of ripe bananas and the garden-fresh charm of shredded zucchini. It’s the kind of cake you make on a slow weekend morning—simple ingredients, no fuss, just honest baking. In this guide, I’ll show you how to make it step by step, share tips from my own rustic French kitchen, and offer variations for every lifestyle. Whether you’re baking for family, prepping for the week, or just treating yourself, this recipe checks all the boxes: moist, wholesome, and full of flavor.

A Slice of Provence in Every Bite

I still remember standing on a wooden stool in my grandmother’s sun-warmed kitchen just outside Aix-en-Provence. We’d pick zucchini straight from the garden and mash overripe bananas while the scent of lavender drifted in through the windows. That’s where I first learned that baking wasn’t just about recipes—it was about rhythm, intuition, and love. This banana zucchini cake recipe was one of the first I ever helped her make. It’s not a fancy cake, but it’s the one I reach for when I need a taste of home.

It’s also a perfect bridge between rustic and modern—a dessert that embraces what’s in season, reduces waste, and still tastes like indulgence. If you’re someone who keeps bananas a little too long on purpose or grows zucchini faster than you can cook it, this cake will quickly become part of your baking rotation. Like many of the treats on Hana Eats, it’s flexible, forgiving, and made to share.

Why Banana Zucchini Cake Deserves a Place in Your Kitchen

Let’s talk about why this cake is worth baking. First off, it’s incredibly moist—thanks to the moisture-rich zucchini and ripe bananas. There’s no need for heavy amounts of oil or butter here. Second, it’s an excellent way to sneak in some extra veggies, especially for picky eaters. Third, this banana zucchini cake recipe is naturally sweetened and can easily be made refined sugar–free.

It’s also adaptable. You can keep it simple for breakfast or snack it up with nuts, dark chocolate chips, or even a cinnamon swirl. One of my readers made it with a honey glaze inspired by my churro waffles and called it “pure joy.” And I agree—this cake feels joyful.

Stay with me, and I’ll walk you through the ingredients, smart substitutions, and baking steps. Up next: exactly what you’ll need to make the perfect banana zucchini cake and how to prep like a pro.

What You’ll Need for the Perfect Banana Zucchini Cake Recipe

This banana zucchini cake recipe calls for pantry staples plus a few fresh ingredients. You likely have most of them on hand already. Here’s what you’ll need:

Basic Ingredients:

• 1 cup mashed ripe bananas (about 2–3 bananas)
• 1 cup grated zucchini (packed and gently squeezed)
• 2 eggs (or flax eggs for a vegan option)
• 1/3 cup neutral oil (avocado, canola, or melted coconut oil)
• 1/3 cup maple syrup or honey (or sugar substitute)
• 1 tsp vanilla extract
• 1 ½ cups all-purpose flour (or a blend with almond flour)
• 1 tsp baking soda
• ½ tsp baking powder
• ½ tsp salt
• 1 tsp ground cinnamon

Optional Add-ins:

• ½ cup chopped walnuts or pecans
• ½ cup dark chocolate chips
• Pinch of nutmeg or cloves for extra warmth

The beauty of this banana zucchini cake recipe is how easy it is to adapt. Want a nut-free version? Skip the walnuts. Prefer gluten-free? Use a 1:1 gluten-free baking blend. For extra texture and nutrition, you can even swap in some oats, similar to the approach in my key lime pie overnight oats.

Preparation Secrets for a Moist, Tender Crumb

Now here’s where it gets interesting. Zucchini has a high water content, which can either be your best friend or your worst enemy in baking. The trick? Grate it finely and press out the excess moisture using a clean towel—but don’t wring it dry. You want it damp, not soggy.

The bananas should be deeply ripe, with plenty of brown spots. This ensures natural sweetness and tenderness. Mash them well until smooth for even texture in the final bake.

When mixing, whisk wet and dry ingredients separately. Fold them together just until combined—don’t overmix or the cake may toughen. This is true for most quick batters, as I explain in my baked feta chicken quinoa bowls post too.

Here’s a quick reference table for smart substitutions:

Ingredient	Substitution
Eggs	2 flax eggs (2 tbsp flaxseed + 5 tbsp water)
All-purpose flour	Almond flour (50%) + oat flour (50%)
Maple syrup	Honey or coconut sugar
Oil	Applesauce (1:1 for lower fat)

These tips make all the difference between a flat loaf and a beautifully risen, golden banana zucchini cake. Coming up next: I’ll guide you step by step through baking, with a few secrets I’ve learned along the way.

How to Make the Best Banana Zucchini Cake Step by Step

Ready to bake? Follow these simple steps for a foolproof banana zucchini cake recipe that delivers on moisture, flavor, and ease. You don’t need a mixer—just two bowls, a whisk, and a spatula.

Step-by-Step Instructions:

1. Prep your pan: Preheat your oven to 350°F (175°C). Grease and line an 8×8-inch square or 9×5-inch loaf pan with parchment paper.
2. Grate the zucchini: Use a fine grater. Measure out 1 cup packed, then gently press it in a towel to remove excess moisture.
3. Mash the bananas: In a large bowl, mash 2–3 very ripe bananas until smooth.
4. Mix wet ingredients: To the bananas, add eggs, oil, maple syrup (or sweetener of choice), and vanilla extract. Whisk until smooth.
5. Combine dry ingredients: In another bowl, whisk together the flour, baking soda, baking powder, cinnamon, and salt.
6. Fold it all together: Add the dry ingredients to the wet. Stir gently until just combined—don’t overmix. Then fold in the zucchini and any mix-ins like chocolate chips or chopped nuts.
7. Bake: Pour batter into prepared pan and smooth the top. Bake for 40–50 minutes, or until a toothpick inserted into the center comes out clean.
8. Cool: Let the cake cool in the pan for 10–15 minutes before lifting it out. Cool completely on a wire rack before slicing.

This cake smells like a warm hug while it’s baking. It has that same cozy kitchen vibe as my sourdough zucchini bread, which also makes use of garden surplus and pantry staples. The center stays soft, and the edges get golden and lightly crisp.

Want to make it even easier? This batter also works great in muffin tins! Just reduce the bake time to about 18–22 minutes. (It’s a trick I mention often—see how I adapted meal prep muffins in my high-protein snack boxes.)

Glazing or Frosting? Here’s What Works Best

This banana zucchini cake tastes fantastic on its own, but if you’re in the mood for a little extra flair, here are three topping options that pair beautifully:

1. Classic Cream Cheese Frosting
Blend cream cheese, a touch of butter, powdered sugar, and vanilla. It adds richness without overpowering the banana and spice notes.

2. Maple Cinnamon Glaze
Mix powdered sugar, maple syrup, a splash of milk, and cinnamon. Drizzle while the cake is still slightly warm for that sticky-sweet finish.

3. No Topping Needed
Honestly, it’s flavorful enough to stand on its own. Especially if you’re serving it with coffee or tucked into a lunchbox.

If you want a more dessert-style twist, you could even swirl in Nutella before baking—kind of like I do with my churro dessert tacos, where a rich filling takes the treat to the next level.

No matter how you top it (or don’t), this banana zucchini cake recipe is one you’ll turn to again and again.

How to Store and Freeze Banana Zucchini Cake Like a Pro

Once your banana zucchini cake has cooled, storage is key to keeping it moist and flavorful. Here’s how to keep it fresh—whether you’re enjoying it right away or saving it for later.

At Room Temperature
Store the cake in an airtight container on the counter for up to 2 days. If your kitchen is warm or humid, consider refrigerating it to avoid spoilage.

In the Fridge
Wrap it tightly or place slices in a sealed container. It’ll stay fresh for up to 5 days. The flavor deepens over time, making it perfect for breakfast or a grab-and-go snack.

In the Freezer
This cake freezes beautifully. Slice it first, then wrap each piece individually in plastic wrap and place them in a freezer-safe bag. They’ll keep for up to 2 months. Just thaw at room temp or give it a quick warm-up in the microwave.

Here’s a quick storage guide:

Storage Method	Duration
Room Temperature	2 days
Refrigerated	5 days
Frozen	2 months

Pro tip: individually frozen slices are perfect for adding to high-protein vegan meal prep lunchboxes. It’s wholesome, satisfying, and easy to portion.

Fun Variations: Muffins, Vegan, Gluten-Free

One of the best things about this banana zucchini cake recipe? It’s flexible. You can tweak it to suit your lifestyle or pantry without sacrificing taste.

Make It Vegan
Substitute the eggs with flax eggs (2 tbsp ground flax + 5 tbsp water), use maple syrup, and ensure your chocolate chips (if using) are dairy-free.

Go Gluten-Free
Swap the all-purpose flour for a gluten-free 1:1 baking blend. You can also use almond flour in combination with oat flour for a denser, more wholesome texture—similar to the base in my edible protein cookie dough.

Try It as Muffins
Spoon the batter into a lined muffin tin and bake at 350°F for 18–22 minutes. It’s perfect for portion control and easy weekday snacks.

Add Fruit or Crunch
Diced apples, shredded coconut, or chopped pecans work beautifully in the batter. A swirl of nut butter or a sprinkle of sea salt before baking? Pure magic.

This is a cake that welcomes creativity. You can keep it classic or dress it up. Either way, it’s a cozy, nourishing treat that always hits the spot.
