I’ve gone completely bananas and a little bit nutty! A recipe for Banana and Walnut Slice

Oh yes, we’re all completely mad here (doesn’t your heart sink when someone really says that to you?  “Don’t mind me, I’m completely mad!!!!” They never, ever are).

On this occasion, however, I have not so much gone bananas as been inundated with bananas.  The ones that are so ripe that you have about a minute to eat them before they turn into alcohol.  Coincidentally, I was also given a carrier bag full of walnuts at Christmas, some of which were used up in some delicious Huntingdon Pears for my last dinner party, but a large amount still remain and must be dealt with.  And remember that the other things you’ll need are storecupboard ingredients.

The only avenue left open to me was a large and rather marvellous Banana and Walnut Slice.  The great thing about this cake, is that you can bake it in three tins and fill it with buttercream or mock cream, or you can bake it in one tin and, when it’s cool (of course it’s cool, I made it), just slice it and spread it with butter.  This recipe makes a substantial cake that will last a few days, so halve the quantity if you only want a small one.


1 x large mixing bowl
1 x food mixer
1 x stick blender or masher
3 x loaf tin – greased and floured

8oz / 240g butter
8oz / 240g dark brown sugar
2 tablspn honey
4 eggs
2 good sized, very ripe bananas – pureed or well mashed
4oz / 120g walnuts – chopped
10oz / 300g wholemeal self-raising flour
1tsp baking powder

Pre-heat the oven to 180 / 350 / 4
Cream the butter and sugar until it is light brown and fluffy
Beat in the honey
Beat in the eggs
Beat in the mashed bananas
Fold in the flour, baking powder and walnuts
Divide the mixture between the three tins
Bake for about 30 minutes until the tops are golden and a knife comes out of the cake cleanly.
Turn the cakes out onto a wire rack to cool
When completely cold, spread mock cream onto the first and second cakes and sandwich all three together.
Ideally, leave for a couple of hours before serving as the mock cream will have firmed up and makes it considerably easier to slice.

If you are baking a loaf that you are not intending to fill with butter cream
Preheat the oven to 160 / 325 / 3
Prepare the mixture as above
Put all the mixture into one tin
Bake for 45 minutes, then cover the tin with foil and bake for about another 15 minutes
Keep testing the cake with a knife until it comes out cleanly

very popular when real cream was not available and less sickly than buttercream

1 x medium mixing bowl
1 x hand mixer

3oz / 90g butter
3oz / 90g icing sugar (approx, you may like a little more – taste it and see)
1 tblspn white flour
1 tblspn milk
1 tsp vanilla essence

Beat the butter, icing sugar and flour together until they form a thick paste
Add the vanilla
Gradually add the milk until it reaches the consistency you want.
*Remember that buttery fillings thicken up after a few hours

  1. I make a similar banana cake (in fact I made two yesterday), but I’m much lazier than you. I bung the bananas in the food processor to whizz them up, then sling in everything else. Much quicker, and less washing up 🙂

    Hi Ramtops. You put everything in, all at once? Does it turn out heavy (in a good way) or more cake-y? And are the ingredients much the same?

  3. I whizz up the bananas first, to give them a fighting chance.

    Then, for two cakes, I add 1lb of plain flour and about 3 heaped tsps of baking powder (I never use SR flour), 8oz of baking marge, 12 oz of sugar (whatever I have about), and four eggs. Whizz it all up, decant into two loaf tins, bake 40 mins at gas 4, then 30 mins at gas 2. Oh, and I sprinkle the tops with caster sugar to give them a glaze.

    Variously, I add walnuts or choc chips or sultanas, vanilla essence, bourbon, cinnamon, mixed spice – it’s one of the most versatile and forgiving recipes I know.

      Well done Ramtops, everyone take note please. Versatility is the key to home cooking and money saving. Use what you have in stock and don’t make things unecessarily difficult.

      By the way, I assume I’m addressing a fellow Pratchett Fan?

    How do you come to have a glut of bananas? Do you grow them yourself? I can understand it with apples or runner beans, but…

    Somewhere at home I’ve got a 1960s pamphlet of banana recipes – I’ll dig it out and see if any are worth mentioning.

    Mashed bananas on toast (with a bit of honey) is a great late-night snack, more digestible than a kebab(!), and a good way to use up the overripe ones.

      EJ: I was given some old bananas by a friend who rummages in the waste box outside the Co-op! They throw away loads of food that is perfectly good but is past its sell by. She, very sensibly, retrieves it!
