Ingredients for banana and walnut cake recipe uk

The perfect British baking lineup: ripe bananas, toasted walnuts, and self-raising flour for that signature tender crumb.

Ingredient Amount Notes
Ripe Bananas 🍌 3 large Mashed before mixing
Self-Raising Flour 🌾 2 ½ cups UK standard for tender crumb
Walnuts 🥜 1 ½ cups Toasted and roughly chopped
Granulated Sugar 🍚 1 ½ cups White or light brown
Large Eggs 🥚 2 whole Room temperature preferred
Unsalted Butter 🧈 ¾ cup Softened, not melted
Vanilla Extract 🌸 1 tbsp Pure extract preferred
Baking Powder 🍞 1 ½ tsp Double-acting preferred
Ground Cinnamon 🌿 1 tsp Freshly ground preferred
Icing Sugar 🍬 ½ cup For dusting, optional
Milk 🥛 ½ cup Whole milk preferred
Salt 🧂 ¼ tsp Fine sea salt

Ripe bananas are non-negotiable here—they’re the secret to that caramelized sweetness. Look for bananas with brown spots at your local Tesco or Sainsbury’s, or grab a bunch from a greengrocer’s stall if you’re feeling fancy. Walnuts should be toasted until fragrant—chop them roughly for that satisfying bite. Self-raising flour is key; Doves Farm is my go-to brand for that perfect lift. And don’t skip the room-temperature eggs—they mix in smoother, giving you that silky texture. If you’re short on time, microwave the butter 40 seconds to soften it without melting.

No ripe bananas? Use 1/4 cup unsweetened applesauce per banana, but the flavor won’t be quite the same. Walnuts too pricey? Pecans or hazelnuts work too, though walnuts give that classic crunch. Self-raising flour out of stock? Mix 2 cups all-purpose flour + 1.5 tsp baking powder. The vanilla extract can be swapped for 1 tsp vanilla sugar if you’re in a pinch. And if you’re baking for a crowd, double the recipe—this cake freezes beautifully for up to 3 months. Just wrap it tightly in cling film and store in the freezer.

This cake stays moist for 3-4 days at room temperature, wrapped in a cake tin. For longer storage, keep it in the fridge for up to 1 week. Reheat slices in the microwave for 10-15 seconds to bring back that warm, gooey banana flavor. Icing sugar is optional, but a light dusting makes it feel extra special. Serve warm with a dollop of clotted cream for the full British tea experience. And trust me, the leftovers taste even better the next day—if there are any left!

Step-by-step instructions for banana and walnut cake

This cake delivers that perfect balance of tender crumb, caramelized banana, and crunchy walnuts—every bite is a revelation.

1

👨‍🍳 Step 1: Toast and Chop the Walnuts

Preheat your oven to 350°F and spread the 1.5 cups walnuts on a baking sheet. Toast them for 8-10 minutes until they release their nutty aroma and turn a rich golden brown. Watch them closely—they burn fast! Once toasted, transfer them to a cutting board and roughly chop them with a sharp knife. I like mine about ¼-inch pieces—big enough to add texture but small enough to disappear into each bite.

Here's the thing—walnuts can taste bitter when raw. Toasting brings out their natural sweetness and enhances their flavor when paired with caramelized banana. Set the chopped walnuts aside—they'll add that essential crunch to every forkful of cake.

2

🍳 Step 2: Mix Wet Ingredients for Maximum Moisture

In a large mixing bowl, mash the 3 large ripe bananas until smooth—no lumps allowed. Then add the 1.5 cups granulated sugar, 2 whole large eggs, 0.75 cup softened unsalted butter, 1 tbsp vanilla extract, 0.5 cup milk, and 0.25 tsp salt. Whisk everything together until the mixture is completely combined and glossy, about 2-3 minutes. You're looking for a thick, smooth batter that coats the back of your spoon.

This is where the magic happens—the bananas provide natural sweetness and moisture, while the butter and milk create that tender crumb. I always use room-temperature eggs and butter for best results—they blend more smoothly and create a lighter texture. If your batter looks too thick, add 1-2 tablespoons of milk to loosen it.

3

👨‍🍳 Step 3: Combine Dry Ingredients Gently

In a separate bowl, sift together the 2.5 cups self-raising flour and 1.5 tsp baking powder. Then add the 1 tsp ground cinnamon and mix gently with a whisk. The reason we sift is to prevent lumps in the batter—self-raising flour already contains baking powder, so we don't want to overmix and develop gluten.

Now, pour the dry ingredients into your wet mixture and fold them together using a spatula. Here's the crucial part: fold just until combined—you should still see some flour streaks. Overmixing develops gluten, which makes the cake tough instead of tender. Then, gently fold in the toasted walnuts, reserving about 2 tablespoons for the topping if you like.

4

🔥 Step 4: Bake to Golden Perfection

Preheat your oven to 350°F and grease two 8-inch round cake pans (or one 9x13-inch pan for a sheet cake). Divide your batter evenly between the pans and sprinkle the reserved walnuts on top. Bake for 25-30 minutes until a toothpick inserted into the center comes out clean and the edges are golden brown.

I always tap the sides of the pans gently when checking for doneness—they should sound hollow. If the top browns too quickly, tent the pans with aluminum foil. The cake should be moist but not gummy when done. Let it cool in the pans for 10 minutes before transferring to a wire rack to cool completely.

5

🍽️ Step 5: Dust with Icing Sugar (Optional)

Once completely cool, dust the top of the cake with 0.5 cup icing sugar using a fine-mesh sieve. This adds a delicate sweetness and makes the cake look stunning. For extra flair, you can also drizzle a simple glaze made from 0.5 cup icing sugar mixed with 1-2 tablespoons milk. Serve slices with a dollop of whipped cream or a scoop of vanilla ice cream for the ultimate indulgence.

This cake keeps well in an airtight container for up to 3 days at room temperature, though I doubt it'll last that long. The moist crumb, caramelized banana flavor, and nutty crunch make every bite irresistible. Trust me, you'll want to bake this again and again!

Pro Tips For Making Banana And Walnut Cake Recipe Uk

  • Mash Bananas Properly: No one likes lumps in their cake. Smash those bananas with a fork first, then push them through a sieve or fine-mesh strainer to remove skins and fibrous bits—this keeps the texture silky rather than gummy. (Yes, it’s extra work, but your cake will thank you.)
  • Toast Walnuts First: Skip the raw walnuts—they’ll turn bitter and release odd flavors. Lightly toast them in a dry pan over medium heat for 3–4 minutes until fragrant, then chop. This adds depth and prevents that "wet cardboard" taste in the final bite.
  • Check Doneness Early: Self-raising flour means this cake rises fast. Start testing with a skewer at 35–40 minutes (depending on your oven). If it comes out clean but the top’s still sinking, tent with foil and let it set—overbaking dries it out faster than you’d expect.
  • Use Room-Temp Eggs: Cold eggs mix unevenly and can curdle when combined with warm banana purée. Crack them into a bowl and let them sit for 10 minutes before folding into the batter. The difference in texture is noticeable, especially in a moist cake like this.

Regional styles of this dish

Traditional British Tea Cake

This recipe is a staple in British tea rooms, where it’s often served with a pot of Earl Grey or a cup of Assam. The walnuts add a satisfying crunch that pairs beautifully with the moist banana layers, making it a favorite for afternoon tea. I’ve seen it served at country house gatherings in the Cotswolds, where it’s dusted with icing sugar and paired with clotted cream. The self-raising flour ensures that signature tender crumb that Brits love. 🍵

Scottish Walnut Banana Loaf

Up north, this cake often appears as a loaf rather than layers, baked in a 9x5-inch loaf tin lined with parchment. The Scots love adding a splash of whisky (1 tbsp) to the batter for depth, which caramelizes beautifully with the bananas. It’s a common treat in Glasgow bakeries, where it’s sliced thick and served with a dollop of whipped cream. The texture stays moist for days, making it perfect for picnics or packed lunches.

Irish Brown Sugar Twist

In Ireland, you’ll find a variation where ½ cup of Irish brown sugar replaces half the granulated sugar. This adds a molasses-like richness that complements the walnuts perfectly. The Irish also love adding a pinch of nutmeg (¼ tsp) alongside the cinnamon, giving it a warm, spiced flavor. It’s a popular cake at St. Patrick’s Day celebrations, often served with a cup of strong Irish coffee. The brown sugar keeps the cake moist for longer, making it a hit for leftovers.

Welsh Walnut and Honey Cake

For a unique Welsh twist, replace the milk with ½ cup honey (I recommend Welsh heather honey) and add an extra ½ cup chopped walnuts. The honey adds a floral sweetness that balances the caramelized bananas beautifully. This version is often baked in a 9-inch round tin and served with a drizzle of extra honey. It’s a favorite in Welsh tea houses, where it’s paired with a cup of Welsh tea—strong and malty.

Northern English Spiced Version

In the North of England, particularly in Yorkshire, you’ll find this cake spiced with an extra ½ tsp ground ginger alongside the cinnamon. This gives it a warming, almost gingerbread-like flavor that’s perfect for colder months. The Yorkshire also love adding a teaspoon of black treacle to the batter, which adds a deep, molasses-like richness. It’s a classic at village fairs and often served with a dollop of custard for extra indulgence.

Cornish Caramelized Banana Cake

Down in Cornwall, the focus is on maximizing the caramelized banana flavor. They often use 4 ripe bananas (instead of 3) and reduce the sugar to 1 cup. The Cornish also love adding a teaspoon of sea salt to the batter, which enhances the natural sweetness of the bananas. This version is baked in a 9-inch round tin and served with a sprinkle of flaky sea salt on top. It’s a beloved dessert in Cornish cream teas, where it’s paired with a slice of Cornish clotted cream.

Frequently asked questions

1

Can I use overripe bananas for this cake?

Overripe bananas are perfect—they're sweeter and mash more easily, giving your cake that rich, caramelized flavor. Just make sure they're soft enough to mash with a fork, not mushy. The darker the spots, the better the flavor, but avoid any that feel too squishy or have mold.

2

What's the best way to store leftovers?

Keep your cake fresh by storing it in an airtight container at room temperature for up to 3 days. For longer storage, wrap it tightly in cling film and refrigerate for 1 week. To revive slices, warm them in the microwave for 10-15 seconds—they'll taste almost as good as fresh!

3

Can I substitute walnuts with another nut?

Yes! Pecans or hazelnuts work well, though walnuts give that classic crunch. For a different texture, try toasted almonds or even chopped dates for a sweeter alternative. Just toast them first to enhance their flavor—it makes all the difference in every bite.

4

Why did my cake turn out dense?

Overmixing the batter or using cold eggs/butter often causes dense cakes. Always mix dry ingredients just until combined, and use room-temperature eggs and softened butter. Also, check your baking powder—it should be fresh (test by mixing with water; it should bubble). A 180°C (350°F) oven is crucial too—too high or low can affect texture.

5

How can I make this cake gluten-free?

Replace the self-raising flour with a 1:1 gluten-free baking mix (like Doves Farm GF) plus 1.5 tsp xanthan gum. Add 1 tbsp extra milk to improve moisture. For best results, use a gluten-free measuring cup and don't overmix. The texture will be slightly different but still delicious!
