For the banoffee mousse, in a non-stick pan take sugar, once sugar melts add sliced bananas and let it reach a deep caramel colour, then add butter and fresh cream and mix well, the mixture will bubble up, keep mixing and make sure the bananas are mashed well in the process, after you get a jam like consistency switch off the flame and let the mixture cool down. Then add melted white chocolate and mix nicely. Finally fold this into whipped cream and refrigerate the mousse for 2 hours.
