Our banana cake recipe is naturally sweet, rich, moist and delicious. This easy-to-make recipe works deliciously well with a cup of tea for one, or if you're feeling generous, up to 12.
With this banana cake recipe, the moist sponge is sprinkled with walnuts and topped with a rich chocolate buttercream to complement the banana flavour. To make this recipe, make sure the bananas you use are nicely ripe and brown - in fact, it's a great way to use up bananas that have been left in the fruit bowl for some time. This will pack your sponge full of sweet flavour and make your banana cake extra moist and soft. If you're not a fan of chocolate buttercream on your banana cake, you can swap this for vanilla instead, or you could even drizzle your banana cake in a light icing sugar and water mix to give it a simple glaze. This easy banana cake recipe serves 12 people, so it's great for a gathering. This easy banana cake only takes 1hr and 15 mins to make, but just 15 minutes to prepare. Easy! Any leftovers (ha!) can be stored in an airtight container for up to 3 days. Looking for more delicious inspiration? We've got lots more cake recipes here!
Watch how to make Banana cake
- 450g overripe bananas
- 95g butter
- 175g granulated sugar
- 2 medium eggs, beaten
- 200g self-raising flour
- ½ tsp salt
- ½ tsp bicarbonate of soda
- 70g chopped walnuts
- 2tsp cocoa powder
- 175g icing sugar, sifted
- Few drops vanilla extract
- Extra chopped walnuts, to decorate (optional)
To make this recipe, preheat the oven to 180ºC/350ºF/Gas Mark 4. Grease and line an 18cm (7in) round cake tin.
Reserve half a banana for the icing and place the rest of the bananas in a mixing bowl. Mash until smooth, then set aside.
In a large mixing bowl, beat together the butter and sugar until pale and fluffy. Gradually add the eggs and bananas, and beat until smooth. Stir in the flour, salt and bicarbonate of soda and mix thoroughly. Quickly mix in the walnuts, then pour into the baking tin.
Bake in the oven for 60-75 mins or until a skewer inserted into the middle comes out clean. Turn out the banana cake and leave to cool on a wire rack.
To make the icing, place the butter and cocoa powder in a small saucepan. Heat until melted. Mash the reserved banana until very smooth. Add the melted butter mixture to the mashed banana and beat well, then add the icing sugar and vanilla extract. Beat thoroughly until very smooth. Use to ice the top of the banana cake once it has cooled. Decorate with chopped walnuts if you wish.
