Banana Cake with Caramel Walnuts Recipe

This moist banana cake recipe is a favourite since my childhood. I’ve added some decadent caramel walnuts on top. Adding a bit of butter to the caramel means you’re less likely to burn it — but don’t walk away and leave it. This cake will keep in the fridge for several days. Use the bananas which have been sitting in the fruit bowl for a few days as they will will have more flavour — the browner the better.
