🍫 This cake is not just a dessert – it’s a whole experience. Imagine the natural sweetness of ripe bananas melting into the richness of cocoa, softened by oats soaked in hot milk until they turn irresistibly creamy.

The walnuts add that wonderful nutty crunch, while the silky topping of melted dark chocolate drips luxuriously down the sides of the round cake, making it as beautiful as it is delicious.

It’s not just about taste either – this cake has that rustic, homemade charm that feels authentic and comforting. Bananas keep the crumb moist, cocoa makes it feel indulgent, oats lend body and subtle chew, and walnuts make every forkful more exciting. A drizzle of glossy dark chocolate on top turns it into something worthy of a bakery window. Whether you’re baking for a weekend treat, a birthday surprise, or just because you deserve something special, this cake is guaranteed to draw attention. It doesn’t need elaborate decoration – the natural textures of oats, banana, walnut, and chocolate speak for themselves. You’ll want to cut into it as soon as it leaves the oven, but patience pays off: once cooled slightly and dressed with melted chocolate, it becomes something magical.
The shine, the crunch, the softness – it’s a dessert that seduces with its look and conquers with its flavour.

👨🍳 How to Make It (Step-by-step)
✔️ Step 1: Soak the Oats
Pour hot milk over rolled oats and let them soften for 10 minutes until creamy.
💡 Soaking prevents dryness and gives the cake a soft texture.
✔️ Step 2: Mash the Bananas
In a large bowl, mash ripe bananas until smooth.
💡 The riper the bananas, the sweeter and more fragrant the cake will be.
✔️ Step 3: Beat the Eggs
Add two eggs to the bananas and whisk until fully combined.
💡 Room-temperature eggs help the batter mix more evenly.
✔️ Step 4: Add Cocoa and Salt
Mix in cocoa powder and a pinch of salt for depth of flavour.
💡 Salt enhances sweetness and boosts chocolate richness.
✔️ Step 5: Combine with Soaked Oats
Fold the creamy oat mixture into the banana-egg-cocoa blend.
💡 Mix gently to avoid overworking and toughening the batter.
✔️ Step 6: Add Baking Powder
Stir in baking powder for a light, fluffy rise.
💡 Always add this closer to baking so it reacts fully in the oven.
✔️ Step 7: Chop and Add Walnuts
Roughly chop walnuts and fold into the batter.
💡 Leave some pieces bigger for surprise crunch in each slice.
✔️ Step 8: Pour into Mould
Grease or line a 7-inch (18 cm) silicone mould and fill with the batter.
💡 Silicone ensures even baking and easy release.
✔️ Step 9: Bake
Bake at 180°C (360°F) for 40 minutes until a toothpick comes out clean.
💡 Avoid opening the oven in the first 25 minutes to keep the cake from sinking.
✔️ Step 10: Decorate with Chocolate and Walnuts
Melt dark chocolate, drizzle on top, and sprinkle with extra walnuts.
💡 Decorate just before serving for the glossiest finish.
