Banana Cake

I once watched a documentary where some of the former chefs at Noma (the restaurant in Denmark that will set you back about £500 for lunch) talked about their current passions. One woman explained that bananas, rather than going off, were merely ripening further as their skins turned black - and were therefore perfect for use in desserts.

It's something New Zealanders have known for decades. We make banana cake.

The best banana cake I ever tasted was made by Lynette Moss, singer for The Wallsockets, shortly before Fran (one of their two guitarists) and I left for the UK together.

If you've been following my baking exploits, you'll want to know how this one went wrong. I'll explain each misstep in the method.

Makes 8 large slices, but can serve up to 12.


For the sponges:

125g butter at room temperature

175g sugar

2 eggs

2 overly ripe bananas, mashed

2 tablespoons boiling milk

1 teaspoon baking soda

1 teaspoon baking powder

225g plain flour

For the filling:

200mls double cream, whipped

1 perfectly ripe banana, thinly sliced

icing sugar for dusting



The state of your bananas: ideally you want two that are overripe for the sponge and one that is perfectly ripe for the filling.


Grease and lightly flour 2 cake tins.


Cream the butter and sugar together, then beat in the eggs.


Mash the 2 overripe bananas then beat them into the mixture.


Imagine my horror when I saw my beautifully creamed butter curdle!

Interestingly, my mistake here was to panic. I haven't made a banana cake in decades, and I'd quite forgotten that this happens.


Heat the milk in a small saucepan till it boils. Add the baking soda and it should foam up.


Stir this well into the less-than-promising looking mix.


Mix the flour and the baking powder and sift it into the mixture.


Stir in/beat until it forms a good cake batter.


Divide the batter equally between your two tins and smooth down the tops.

Bake in a preheated oven at 180ºC for 20 minutes, or until a sharp knife or skewer comes out clean when inserted near the centre.

Do not overcook or give them a couple of extra minutes (like I did). The result is not as moist.


Remove the tins from the oven and let them stand for 10 minutes before loosening the sides with a knife, removing the sponges, and placing them to cool on a cooling rack - the OTHER side up, not the one you see in my photograph.

Let them cool completely before filling.


Beat your cream till it is part way between the soft-peak/firm-peak stage. Do not beat it till it's practically butter (like I did).


Invert one of the sponges and spread it with the whipped cream.


Slice the banana thinly and evenly over the cream.


Top with the second sponge and give it a dusting of icing sugar through the mesh of a sieve.
