Ingredients for banana cake recipe uk
Pantry staples plus overripe bananas—this British classic needs just 11 ingredients for golden perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Overripe Bananas 🍌 | 3 large | Mashed thoroughly for sweetness |
| Self-Raising Flour 🌾 | 2 ½ cups | British-style, no baking powder |
| Condensed Milk 🥛 | 1 can (14 oz) | Traditional British ingredient |
| Unsalted Butter 🧈 | 1 cup | Softened, room temperature |
| Granulated Sugar 🍚 | ½ cup | Optional for extra sweetness |
| Large Eggs 🥚 | 2 whole | Room temperature for best mix |
| Vanilla Extract 🌸 | 1 tbsp | Pure, high-quality preferred |

The bananas are the star, so look for those with brown speckles—they're sweeter and more flavorful. Tesco or Sainsbury's usually have good stock, especially in their organic section. If you can't find overripe ones, ripe bananas with a few brown spots work too, but mash them extra well. The self-raising flour is key—British brands like Dr. Oetker's or J. Arthur Rank are perfect since they already contain baking powder. No need to add extra unless your flour is plain.
No condensed milk? Swap for Greek yogurt or plant-based yogurt—just reduce by 2 tbsp to compensate for moisture. Short on vanilla? Vanilla sugar or a scraped vanilla pod works in a pinch. The butter should be soft but not melted—microwave for 20 seconds if it's too firm. For a lighter texture, replace half the butter with applesauce or yogurt. And if you're feeling fancy, add chopped walnuts or chocolate chips to the batter before folding.
This cake keeps beautifully—3 days at room temperature wrapped in cling film, or 5 days in the fridge. For longer storage, slice and freeze portions for up to 3 months. I always bake an extra small cake to share with neighbors—it disappears fast! Dust with icing sugar right after baking while still warm for that classic British finish. The hidden banana fold? Don't skip it—that's what keeps it moist for days.

Step-by-step instructions for banana cake with hidden banana fold
This classic British banana cake delivers a wonderfully moist crumb and that signature golden crust everyone loves.
Prepare the Banana Mixture
Start by mashing the 3 large overripe bananas thoroughly in a large mixing bowl until completely smooth. You'll know they're ready when no lumps remain and the mixture is uniformly creamy. This step is crucial—the riper the bananas, the sweeter and more flavorful your cake will be.
In a separate bowl, whisk together the 1 cup unsalted butter and 0.5 cup granulated sugar until light and fluffy. This should take about 3-4 minutes using an electric mixer on medium speed. The butter should become pale in color and nearly double in volume. This creaming process incorporates air, which helps create that tender crumb we're after.
Combine Wet Ingredients
Add the mashed bananas to the butter-sugar mixture and blend until fully incorporated. Then beat in the 2 whole large eggs, one at a time, mixing well after each addition. Stir in the 1 tablespoon vanilla extract and 1 teaspoon baking powder. The mixture should be smooth and well-combined at this stage.
Gradually add the 2.5 cups self-raising flour and 0.5 teaspoon salt, mixing just until combined. Be careful not to overmix—you should still see some flour streaks. The batter should be thick but pourable. If it's too thick, you can add 1-2 tablespoons of milk to loosen it slightly, but try to keep it as close to the original recipe as possible.
Create the Hidden Banana Layer
Pour half of the batter into a 9-inch round cake tin that has been lightly dusted with 0.5 cup all-purpose flour. Gently spread it out evenly. Now, take the remaining batter and spread it over the first layer, leaving a 1-inch border around the edges. This creates the classic "hidden banana fold" that makes this cake special.
Using a spoon or small knife, gently swirl the top layer into the bottom layer to create a marbled effect. This isn't just for looks—it ensures even distribution of the banana flavor throughout the cake. Tap the cake tin gently on the counter to remove any air bubbles that may have formed during mixing.
Bake to Golden Perfection
Preheat your oven to 350°F (175°C). Place the cake tin in the center of the oven and bake for 45-50 minutes, or until a skewer inserted into the center comes out clean. The cake should be golden brown on top and spring back slightly when pressed gently in the center.
I like to check the cake after 40 minutes—sometimes ovens run hot, and you don't want to overbake. The edges should be pulling away from the sides of the tin slightly, and the top should have a beautiful golden crust. If it's browning too quickly, cover loosely with foil to prevent over-browning while allowing it to cook through.
Cool and Finish
Remove the cake from the oven and let it cool in the tin for 10 minutes. Then transfer it to a wire rack to cool completely. Once cooled, dust the top generously with 0.25 cup icing sugar using a fine sieve. This final step adds that classic British touch and balances the rich banana flavor.
The cake will be moist and tender with a perfect golden crust. Serve slices warm with a dollop of whipped cream or a pat of butter for the ultimate British banana cake experience. This recipe makes 12 generous servings, perfect for sharing with family or friends.
Pro Tips For Making Banana Cake Recipe Uk
- Mash Bananas Properly: Skip the blender—overripe bananas should be mashed with a fork until smooth with just a few tiny lumps. I learned this the hard way after a cake turned out dense and gummy; the lumps break down in baking, but too much blending releases excess liquid, making the texture gluey.
- Use Room-Temp Butter: Softened butter mixes better into the flour and sugar, preventing streaks that make the cake look uneven. Take it out of the fridge 30 minutes before mixing—yes, even if you’re impatient like me, it’s worth the wait.
- Don’t Overmix the Batter: Stir just until the flour disappears—overmixing develops gluten, which turns your cake into a dense brick. Self-raising flour is forgiving, but two or three gentle folds are all it needs.
- Add Condensed Milk Last: Fold it in at the very end to keep the cake moist without making it sink. I used to mix it in early, and the cake would collapse in the middle—now I add it like a final whisper of richness.
Health benefits of these flavors
Natural Energy Boost
Bananas provide a natural energy boost thanks to their high potassium and natural sugars content. A single medium banana contains about 422mg of potassium, which helps regulate blood pressure and muscle function. The natural sugars in overripe bananas give you quick energy without the crash, making this cake a great post-workout treat or afternoon pick-me-up. 💪
Rich in Fiber
This cake delivers dietary fiber from the whole bananas and self-raising flour, supporting healthy digestion. A serving contains about 3-4 grams of fiber, which helps keep you feeling full longer and supports gut health. The fiber content also helps stabilize blood sugar levels, preventing energy crashes after eating.
Protein for Satiety
The eggs and condensed milk in this recipe add quality protein—about 4-5 grams per slice. Protein helps keep you satisfied longer and supports muscle repair. The combination of protein and fiber makes this cake more filling than many other desserts, which is great for those watching their portions.
Vitamin B6 Support
Bananas are an excellent source of vitamin B6, with one medium banana providing about 20% of your daily needs. This vitamin plays a crucial role in brain development and function, as well as metabolism. The cake retains enough vitamin B6 to contribute to your daily intake while still being a delicious indulgence.
Healthy Fat Balance
The butter and condensed milk provide healthy fats that support brain function and hormone production. While this isn't a low-fat dessert, the fats are balanced by the fiber and natural sugars, making it a more satisfying treat than many store-bought cakes. The fats also help your body absorb fat-soluble vitamins from the bananas.
Antioxidant Benefits
Overripe bananas contain polyphenols and antioxidants that help combat oxidative stress in your body. These compounds support cellular health and may help reduce inflammation. The cake retains these benefits while providing a comforting dessert that feels indulgent but is actually packed with good-for-you nutrients. 🌱

Frequently asked questions
Can I use ripe instead of overripe bananas for this UK banana cake?
Yes, but with a small adjustment! Use 4 ripe bananas instead of 3 overripe ones and add 1 tablespoon extra sugar to compensate for the lower natural sweetness. The cake will still be delicious, just slightly less sweet. For best results, mash them thoroughly to avoid lumps in the batter.
What's the best way to store banana cake in the UK climate?
Wrap the cake tightly in cling film and store at room temperature for up to 3 days. For longer storage, refrigerate for 5-7 days or freeze slices for 3 months. The UK's humid climate can make cakes go stale faster, so keep it in an airtight container with a slice of bread to absorb excess moisture.
Why does my banana cake come out dense instead of moist?
Overmixing or underbaking are the most common culprits. Mix just until combined (you should still see flour streaks) and bake until a skewer comes out clean. Also ensure your bananas are thoroughly mashed—lumps prevent even moisture distribution. Check your oven temperature with an oven thermometer as UK ovens can vary by 25°C—adjust if needed.
Can I make this banana cake vegan?
Replace the 2 eggs—with 2 tablespoons ground flaxseed + 6 tablespoons water—let sit for 5 minutes to gel. Use vegan condensed milk—or coconut milk + 2 tbsp sugar reduced by 2 tbsp. For butter, use vegan margarine—or coconut oil. The texture will be slightly denser but still delicious.
What's the difference between this cake and American banana bread?
This UK banana cake uses self-raising flour—no baking powder needed, while American banana bread typically uses all-purpose flour + extra baking powder. The hidden banana fold technique creates a more even texture than the dense, fudgy American version. Also, UK recipes often include condensed milk—which adds sweetness without extra sugar.
