Easy Banana Cake with Chocolate Glaze
The first time I tasted my grandma’s zucchini swirl cake, I remember thinking it was some kind of magic. It was this perfect balance of moist, tender cake with swirls of sweet cinnamon and shredded zucchini peeking through—like a cozy hug in dessert form. I was probably about 10 years old and sat at her kitchen table, sticky fingers from licking the batter spoon, feeling inspired that something so simple could taste this incredible. Now, years later, I always do this when I need a dessert that feels homemade, comforting, and just a little bit special. Honestly, I love how it’s a sneaky way to get kids (and grown-ups!) to eat their veggies without a fuss. It’s kind of like a surprise inside a classic cake, and it disappears faster than I can say “second slice” every single time. This one’s a lifesaver on busy nights when a quick but impressive treat is what you need. Trust me, once you make it, it’s going to be a staple in your baking lineup too.
What is Zucchini Swirl Cake?
Think of zucchini swirl cake as a cozy, cake version of a cinnamon roll—think soft, tender crumb with swirls of cinnamon sugar goodness running through it, but with an added surprise of shredded zucchini baked right in. It’s essentially a moist sponge cake that’s upgraded with the subtle sweetness and moisture of zucchini. The name might throw some people off at first—“zucchini?” — but once it’s baked, you’d never guess there’s a vegetable hidden inside. This cake is a classic comfort dessert, often baked in the fall or summer when zucchini plants are overflowing. It’s a wonderful way to make use of garden bounty or just stretch a few zucchinis into something delightful. The swirl pattern makes it look as pretty as it tastes, and it’s versatile enough to serve for breakfast, brunch, or a sweet ending that’s not overly indulgent but still incredibly satisfying.
Why you’ll love this recipe?
What I love most about this zucchini swirl cake is how it combines the humble zucchini with a burst of cinnamon and sugar—it’s like a little slice of nostalgia.

Plus, it’s super easy to make—no complicated techniques, just a few bowls and gentle folding. This one’s a budget-friendly option, too, since you probably already have most of the ingredients in your pantry: eggs, flour, sugar, cinnamon, and zucchinis from your garden or store. I’ve tested this with different kinds of sweeteners, like honey or maple syrup, and it turns out delicious every time. The versatility is key—as leftovers, it’s even better the next day when the flavors meld. Honestly, what I love most about this is it’s a treat that feels homemade and caring, perfect for sharing with family or friends who appreciate a little sweetness with a side of warmth.
How do I make Zucchini Swirl Cake?
Quick Overview
This cake is a straightforward one-bowl batter that’s gently swirled with cinnamon sugar and shredded zucchini, then baked until golden. The magic comes from the way the zucchini keeps the cake remarkably moist and tender, while the cinnamon swirl adds a touch of spice and beauty. I like to prepare everything ahead—shred the zucchini, mix my dry and wet ingredients—and then just pour, swirl, and bake. It’s actually quite forgiving; I’ve made this dozens of times and it never fails. Whether you’re baking for a weekend brunch or a cozy afternoon treat, it’s a no-fuss, absolutely delicious bake that’ll brighten up any day.
Ingredients
For the Main Batter:
- 1 ½ cups all-purpose flour (I always use unbleached for a richer flavor)
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- 1 teaspoon ground cinnamon (more if you love it!)
- ½ cup granulated sugar (or coconut sugar for a bit more warmth)
- ½ cup brown sugar
- ½ cup vegetable oil (or melted butter if you prefer a richer taste)
- 3 large eggs
- 1 teaspoon vanilla extract
- 1 cup shredded zucchini (squeezed dry to remove excess moisture)
For the Filling:
- ½ cup light brown sugar
- 1 tablespoon ground cinnamon
- 2 tablespoons melted butter
For the Glaze:
- ½ cup powdered sugar
- 1-2 teaspoons milk (or lemon juice for a tangy twist)
- Optional: vanilla extract or a splash of almond extract
Step-by-Step Instructions
Step 1: Preheat & Prep Pan
Set your oven to 350°F (175°C). Grease a 9-inch round springform pan or line it with parchment paper—trust me, this cake loves a smooth release. Prepare your shredded zucchini by squeezing out as much moisture as possible; I usually do this after shredding with a clean dish towel or paper towels. Moisture is the enemy of a good crumb, so this step is key to avoiding a soggy bottom.
Step 2: Mix Dry Ingredients
In a large bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon. This helps distribute everything evenly so your baking is uniform and fluffy. I find that sifting isn’t necessary, but it does make the batter extra tender.
Step 3: Mix Wet Ingredients
In a separate bowl, beat the eggs, sugars, oil, and vanilla until the mixture is smooth and slightly frothy. I like to do this with a whisk—sometimes I add a splash of milk to loosen it up a bit if it’s feeling thick. Incorporating air here makes the cake rise just right.
Step 4: Combine
Gently fold the wet ingredients into the dry, just until combined. Avoid overmixing—this keeps the cake tender and light. Then fold in the shredded zucchini. If you want to add a handful of chopped walnuts or chocolate chips, now’s your chance!
Step 5: Prepare Filling
Mix the brown sugar and cinnamon together. Melt the butter and set aside. This filling adds the lovely cinnamon swirl effect, so don’t skip it. For a twist, try adding a pinch of nutmeg or cardamom for more depth.
Step 6: Layer & Swirl
Pour half of the batter into your prepared pan. Sprinkle half of the cinnamon sugar mixture evenly over the batter. Add the rest of the batter on top and then sprinkle with remaining cinnamon mixture. Using a butter knife or skewer, gently swirl through the batter to create beautiful, marbled ribbon-like patterns. Trust me, a gentle swirl creates the most charming design!
Step 7: Bake
Bake for about 40–45 minutes, or until a toothpick inserted in the center comes out clean. It’s okay if the top is golden—if it’s browning too fast, tent with foil. Every oven is different, so start checking around the 40-minute mark. The smell alone will make your kitchen feel warm and inviting.
Step 8: Cool & Glaze
Let the cake cool for at least 15 minutes in the pan, then transfer to a wire rack. Drizzle the glaze over the slightly warm cake—it soaks in beautifully, and it’s my favorite part. For a thinner glaze, add a splash more milk; for a thicker one, add a bit more powdered sugar. I sometimes add grated lemon zest into the glaze for a fresh, zesty kick.
Step 9: Slice & Serve
Use a sharp serrated knife to cut clean slices; this cake can be a little delicate. Serve it warm or at room temperature. I love pairing it with a cup of tea or a cold glass of milk—those cinnamon swirls and zucchini moistness are just irresistible. Honestly, a spoonful of Greek yogurt dolloped on top is heaven, especially if you like a touch of tang with your sweetness.
What to Serve It With
This zucchini swirl cake is so versatile. For breakfast or brunch, I love serving it with a weak coffee or a chai latte, and maybe some fresh fruit on the side. It’s adorable on a cake stand with a drizzle of extra glaze for a pretty presentation. When I serve it as a dessert, I like to add a scoop of vanilla ice cream or a dollop of whipped cream—trust me, the warm and cold combo is divine. I’ve also made it into little muffin-sized bites for kid-friendly snacks, which disappear even faster! At family gatherings or potlucks, everyone always asks for the recipe, and I happily share. This cake’s simple, wholesome charm makes it a hit anywhere it shows up.
Top Tips for Perfecting Your Zucchini Swirl Cake
From years of making this, I’ve learned a few tricks that can take your cake from good to *amazing*. First, squeezing out excess moisture from the zucchini is essential—if it’s too wet, your cake could turn soggy or dense. I usually do this with a clean dish towel, pressing out as much water as I can. Second, don’t overmix the batter; a gentle fold preserves the light, fluffy texture. When swirling in the cinnamon mixture, try to keep the layers visible—this gives it that beautiful marbled look and ensures every bite has a hint of spice. For ingredient swaps, I’ve tested using coconut sugar and olive oil with great results—just remember that these changes slightly affect flavor and texture, so I tweak accordingly. Baking at a slightly lower temperature for a longer time can prevent over-browning, especially with darker pans. When it comes to the glaze, I often add a splash of almond extract or citrus zest for a little extra zing. These little adjustments have helped me perfect this cake over the years, and I promise, with patience, yours will turn out just as cozy and delicious.
Storing and Reheating Tips
This cake keeps surprisingly well—much better than I expected. If you’re planning to enjoy it over a couple of days, I recommend wrapping it tightly with plastic wrap or storing it in an airtight container at room temperature for up to two days. After that, pop it into the fridge—just make sure it’s well covered. The zucchini helps keep it moist, but refrigerating slows down any chances of spoilage. To reheat, I usually microwave slices for about 15-20 seconds, just until slightly warm, or warm it gently in a low oven for 10 minutes. If you’re freezing it, wrap individual slices tightly in plastic wrap and then foil; I find that the texture stays perfect for up to 3 months. When ready to serve, let it thaw at room temperature for about 30 minutes. I avoid adding glaze before freezing, as it can get a little gloopy when thawed. When you’re ready, drizzle the glaze over the cake after reheating for a fresh, glossy finish. Honestly, leftovers are a whole new delight—morning, noon, or night—so it’s worth making a double batch!
