Preheat the oven to 170 C / Gas 3. Grease and line two 450g (1 lb) loaf tins.
Cream the margarine and sugar together until light and fluffy. Beat in the mashed bananas and gradually add the eggs. Fold in the flour, sultanas, glace cherries and walnuts. Divide between prepared loaf tins.
Bake in the centre of the preheated oven until a skewer inserted into the centre of the cake comes out clean, 75 to 90 minutes. Allow to cool before serving.
For a pure cherry loaf, omit the sultanas and add an extra 50 to 70g of glace cherries.
This was fabulous and a great way to use our over-ripe bananas. In Fact I now buy bananas with a view to them not getting eaten so I can bake this again! We aren't keen on sultanas so I substituted the same quantity of dried mixed fruit which worked beautifully. And the one I had frozen tasted just as good when defrosted. - 17 Aug 2016
