Combine the melted butter with the Ginger nuts and place the mixture at the bottom of your chosen glasses pressing down with the back of a teaspoon,
Add as much of a caramel layer as you like (I prefer more biscuit base to caramel),
Place the banana on top of the caramel followed by the crystallised ginger of you are using it,
Top with lightly whipped cream and the melted ginger flavoured chocolate,
Garnish with the chopped walnuts which you may like to toast beforehand to give added flavour,
This dessert does not need to be refrigerated before eating,
I made them and they were eaten straight away,
They could be prepared and stored in the fridge until you wish to eat them later in the day or the following day if you have good willpower!
