The recipe notes said: "This cake is a joy - banana, courgette and carrot are the hidden gems that children will not realise are there. To give added interest and texture, use fresh or dried banana slices for decoration. This is not a deep cake, as it has a closer texture than a plain sponge."
Ingredients:For the cake:
225g self-raising flour
175g caster sugar
One teaspoon of baking powder
Four free-range eggs
225ml sunflower oil
100g grated carrot
100g banana, mashed
100g grated courgette
75g chewy dried banana slices, broken into pieces
For the icing:
100g butter, softened
100g full-fat cream cheese
One teaspoon of vanilla extract
225g icing sugar
Method:Preheat the oven to 180C or 160C Fan and then grease two loose-bottomed 20cm sandwich cake tins and line the bases with baking paper.
Put the flour, sugar and baking powder in a large bowl before beating the eggs in a separate bowl. Add the oil, carrot, banana and courgettes to the eggs and stir.
Add the wet ingredients to the dry and whisk together until combined. Divide the mixture between the two tins and bake for 25 to 30 minutes.
Leave to cool in the tins for 10 minutes, and then turn onto a wire rack to cool completely.
To make the icing, place the butter and cream cheese in a large bowl and whisk with an electric whisk until combined.
Add the vanilla and the icing sugar, whisking until light and fluffy. Once the cake is completely cool, spread half of the icing over one cake.
Sandwich the cakes together, then spread the remaining icing on the top and swirl. Arrange dried banana slices in a ring or spiral pattern on top of the cake.
Cut into slices to serve and enjoy. This cake can be made a day ahead and iced on the day of serving, or the un-iced cake freezes well.
