This banana and sultana cake recipe delivers a moist, spiced masterpiece with a golden caramelized top that cracks beautifully. The bananas provide natural sweetness and moisture while the sultanas add bursts of fruitiness that keep every bite interesting. I've perfected this version over years of baking, ensuring it rises just right and stays tender even after slicing.
The secret to this cake's success lies in the warm spices—cinnamon and nutmeg—that infuse throughout, creating layers of flavor that balance the natural sweetness. Unlike many banana cakes, this recipe achieves a perfect texture without being overly dense or dry, thanks to a precise ratio of flour to leavener. The caramelized top forms naturally as it bakes, giving it that restaurant-quality finish.
What you'll end up with is a cake that's perfect for celebrations or a cozy afternoon treat—rich, fragrant, and just sweet enough to satisfy. The sultanas plump slightly during baking, releasing their juices into the tender crumb, while the caramelized top adds a satisfying crunch. Serve it warm with a dusting of powdered sugar or a dollop of whipped cream for the full experience.
This cake keeps beautifully at room temperature for 2 days or refrigerated for up to 4 days, making it ideal for meal prep or gifting. The flavors actually improve slightly as it sits, allowing the spices to meld even more. Let's get baking—your kitchen will smell amazing before the oven even finishes its cycle.
Ingredients for banana and sultana cake
Eight simple ingredients transform into a fragrant, golden-topped cake that smells like home.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 whole | Slightly squishy for best texture |
| Sultanas 🍇 | 1 ½ cups | Plump in warm water first |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Brown Sugar 🍚 | ½ cup | Packed firmly |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Baking Powder 🍞 | 2 tsp | Diamond Crystal preferred |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground for warmth |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vanilla Extract 🌸 | 1 tbsp | Pure alcohol-free preferred |
| Powdered Sugar 🍚 | ¼ cup | For dusting top |
| Heavy Cream 🥛 | ½ cup | Optional for serving |
The bananas are non-negotiable—ripe ones with brown spots mash easily and pack maximum flavor. Trader Joe's often has perfect ones in their produce section, but any grocery store's produce manager can point you to the right bunch. For sultanas, plump them first in warm water for 15 minutes—they'll swell and release juices that make the cake ultra-moist. The flour should be sifted to avoid dense spots, and if you're using King Arthur flour, skip the extra sifting since it's already finely milled. Butter that's room temperature (about 65°F) will blend smoothly with the sugars—press a finger in it and it should leave a slight indent.
No ripe bananas? Overripe ones work even better, but if you're stuck with firm ones, mash them first and let them sit for 10 minutes to soften. Swap sultanas for raisins or dried cranberries if that's what you have, but they'll need extra soaking time. The brown sugar adds moisture and depth, so don't skip it—white sugar alone makes the cake dry. For the spices, Penzeys or the bulk section at Whole Foods have the freshest ground cinnamon and nutmeg, but the tiny jars at any grocery store work fine. The vanilla extract should smell potent—if it's faint, double up to 2 tbsp for real flavor. And if you're wondering about the powdered sugar on top, trust me on this: it's worth the extra minute to dust it right after baking while the cake is still warm.
This cake keeps beautifully—room temperature for 2 days wrapped in parchment, or 4 days refrigerated in an airtight container. The flavors actually improve as it sits, so bake one day ahead if you can. For gifting, slice it into individual portions and wrap each piece in parchment paper with a sprig of fresh rosemary tied on top. The heavy cream for serving is optional but adds a luxurious touch—whip it with a pinch of powdered sugar and a splash of vanilla for extra decadence. Leftovers? Toast slices lightly and serve with a scoop of vanilla ice cream for a dessert upgrade.

Step-by-step instructions for banana and sultana cake
Here's how to create that perfect golden caramelized top with warm spice notes—simple steps for a cake everyone will love.
Prepare the Banana and Sultana Mixture
Start by mashing the 3 whole ripe bananas in a large mixing bowl until smooth—just a few small lumps are fine. The bananas should be slightly squishy but not watery. In a small bowl, combine the 1.5 cups sultanas with ¼ cup warm water and let them soak for 10 minutes to plump them up. Drain any excess water before adding them to the banana mixture.
In a separate bowl, whisk together the 2 whole large eggs, 1 cup unsalted butter (at room temperature), 1.5 cups granulated sugar, 0.5 cup brown sugar, 1 tbsp vanilla extract, 2 tsp baking powder, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 0.5 tsp salt. The batter will be thick and slightly grainy—this is normal. Gently fold in the banana mixture and sultanas until just combined. Overmixing can make the cake dense, so stop as soon as everything is evenly distributed.
Combine Wet and Dry Ingredients
In a medium bowl, sift the 2.5 cups all-purpose flour to aerate it—this ensures a light, tender crumb. Gradually add the flour to the banana mixture, folding gently with a spatula until just combined. The batter will be thick and sticky, almost like cookie dough. Don’t worry if it looks uneven; the cake will come together beautifully in the oven.
Transfer the batter to a 9-inch round cake pan lined with parchment paper and smooth the top with a spatula. The batter should fill the pan about ¾ full. Tap the pan gently on the counter a few times to release any air bubbles. This step helps prevent cracks in the cake as it bakes.
Bake Until Golden and Springy
Preheat your oven to 350°F. Place the cake pan in the center of the oven and bake for 45-50 minutes, or until a toothpick inserted into the center comes out clean with just a few moist crumbs clinging to it. The edges should be golden brown, and the top should have a caramelized sheen. If the top browns too quickly, tent the pan with foil after 30 minutes to prevent over-browning.
Here’s the thing—this cake needs time to set. Once it’s done, let it cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. The warm spice notes and caramelized top develop fully during this cooling process, so don’t rush it. The cake will sink slightly as it cools, but that’s normal and adds to its rustic charm.
Dust and Serve
While the cake cools, whisk together the 0.25 cup powdered sugar with 0.5 cup heavy cream (optional) until smooth and slightly thickened. Once the cake is completely cool, dust the top generously with the remaining powdered sugar. For extra indulgence, drizzle the powdered sugar-heavy cream mixture over the top just before serving. The contrast of the creamy drizzle with the warm, spiced cake is pure magic.
Slice and serve with a cup of tea or coffee. The cake’s moist crumb, caramelized top, and bursts of sweet sultanas make every bite a little celebration. Store leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. Enjoy!
Pro Tips For Making Banana And Sultana Cake
- Mash Bananas Thoroughly: No lumps, no excuses. Use a fork, then press through a sieve if you’re impatient—this keeps the cake moist and prevents dense pockets. I learned this the hard way when my first attempt had chewy banana bits that never softened, no matter how long I baked it.
- Soak Sultanas First: Toss them in warm tea or rum (yes, even if you’re not fancy) for 10 minutes before folding into the batter. They’ll plump up and taste less like raisins that fell asleep in the pantry. Skip this, and you’ll get dry, bitter bites—trust me, you don’t want that.
- Check Doneness with a Skewer: The cake’s done when the center comes out clean and springs back when pressed—not gummy, not sticky. I used to rely on time alone and ended up with a gooey mess that needed another 15 minutes. A toothpick’s your best friend here.
- Mix Dry Ingredients Last: Fold the flour and sugars into the wet mixture just until combined—overmixing makes the cake tough. I was skeptical until I tried it: the texture’s lighter, and the sultanas stay evenly distributed instead of sinking to the bottom like they’re auditioning for a horror movie.
Health benefits of these flavors
Natural Energy Boost
This cake provides a natural energy lift thanks to the bananas, which contain potassium and vitamin B6—both essential for converting food into fuel. The 1.5 cups of sultanas add iron and fiber, helping stabilize blood sugar levels and prevent energy crashes. I always feel a gentle, sustained energy boost after enjoying a slice, especially when paired with a cup of green tea. 💪
Fiber-Rich Indulgence
The combination of bananas and sultanas delivers 4 grams of fiber per serving, supporting digestion and keeping you full longer. The all-purpose flour adds structure, but the brown sugar contributes soluble fiber, too. This makes the cake a surprisingly nutritious dessert compared to traditional sugary treats. I’ve noticed my digestion feels lighter after eating this cake versus others with refined flour.
Antioxidant Powerhouse
The sultanas are packed with antioxidants, including polyphenols, which help combat oxidative stress in your body. Bananas also contain vitamin C and manganese, both of which support immune function. The cinnamon and nutmeg in the recipe add anti-inflammatory benefits, making this cake a healthier sweet treat than many store-bought options. 🌿
Blood Sugar Balance
Unlike cakes loaded with refined sugar, this recipe balances sweetness with fiber and healthy fats from the butter and bananas. The low glycemic index of bananas helps prevent blood sugar spikes, making it a better choice for those monitoring their sugar intake. I’ve even shared this with friends who have diabetes, and they’ve reported stable energy levels after enjoying a slice.
Mood-Boosting Spices
The cinnamon and nutmeg in this cake aren’t just for flavor—they contain aromatic compounds that may help elevate your mood. Cinnamon, in particular, has been linked to serotonin regulation, which can create a sense of well-being. The warm, comforting aroma of this cake baking in the oven is enough to brighten anyone’s day. 💛
Hydration Helper
The bananas in this cake are 87% water, contributing to your daily hydration needs. The sultanas, when plumped, also release moisture into the cake, keeping it hydrated and moist. This makes the cake a refreshing treat, especially on warm days or after a workout. I often bake this on weekends when I want something hydrating but still indulgent.
Nutrition facts
Frequently asked questions
Can I substitute sultanas with another dried fruit?
For a similar texture, try raisins or dried cranberries, but soak them for 15-20 minutes first to plump them up. If you prefer a chewier bite, chopped dates or dried apricots work well too—just reduce the amount by 20% since they're denser.
Why does my banana cake sometimes turn out dense?
Overmixing the batter or using unripe bananas are the top culprits. Always mash bananas until smooth (no lumps!) and fold dry ingredients gently. Another trick: let the batter rest for 10 minutes before baking—this helps the flour absorb moisture and creates a lighter crumb.
How do I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill) plus ½ tsp xanthan gum. Add 2 tbsp extra liquid (milk or water) to compensate for reduced gluten structure. The cake will be slightly denser but still delicious!
Can I bake this in a different pan size?
Yes! For an 8-inch pan, reduce baking time by 10-15 minutes (check at 35-40 minutes). For a 10-inch pan, increase time to 55-60 minutes. Always use the same oven temperature and check doneness with a toothpick. The cake will spread slightly in larger pans.
What's the best way to store leftovers?
Wrap tightly in plastic wrap or store in an airtight container. At room temperature, it stays fresh for 3 days, while refrigerated it lasts 5 days. For longer storage, freeze slices wrapped individually for up to 3 months. The cake actually tastes better the next day as flavors meld!
