Spiced Banana Cake with Butterscotch icing
 
 Yet another loaf cake to add to my repertoire - well the recipe used a 900g loaf tin, but I wanted a round cake so used a 20cm springform tin. Inspiration for the cake was a few very ripe bananas in the fruit bowl. I rarely use alcohol in cakes, but this time I did what the recipe said, and soaked the sultanas in the rum.  I wanted to try a different topping so I used a butterscotch one I'd wanted to try for ages - I know it has a lot of sugar in it, but for a special occasion..........!   100g sultanas  50ml rum  185g plain flour  2 tspn baking powder  ½ tspn bicarb  pinch salt  2 tspn cinnamon - I used 3 tspns  125g soft unsalted butter  150g light soft brown sugar  2 large eggs  4 small very ripe bananas  1 tspn vanilla extract   For the icing:  75g golden caster sugar  15g butter  50g light muscovado sugar  1 tbspn golden syrup  75ml double cream   In a small pan pour the rum over the sultanas and bring to the boil. Remove from the heat and leave to soak.   Preheat the oven 17...
