Preheat the oven to 180°C (fan)/200°C/gas mark 6. Grease and base line a 1kg loaf tin with a sheet of baking parchment.
Add 175g soft brown sugar, 250g plain flour, 1/2 tsp bicarbonate of soda, 1 tsp mixed spice and 1 tsp ground cinnamon to a large bowl. Whisk gently until thoroughly combined.
Place 100ml water, 100ml maple syrup and 100ml sunflower oil into a small saucepan and bring to the boil, stirring constantly so that it doesn't burn. As soon as it's just boiling pour it over the dry ingredients and stir well until combined.
Stir in the 2 mashed bananas, 50g mixed dried fruit and 50g dried cranberries
Pour into the prepared tin and bake for 45 minutes turning the tin around halfway until well risen and firm to the touch.
Allow to cool in the tin.
