In a large pan of water, boil the unopened can of condensed milk for 2 hours, caramelizing the contents of the tin.

Meanwhile, mix together the crushed digestives and melted butter. Line a 9 in flan pan with a removable base and spread the biscuit mixture evenly over the tin. Cover and chill for 2 hours.
Top the biscuit layer with the caramelized condensed milk and then top with a layer of bananas.
Whip the cream and spread over the caramel mixture.
Sprinkle the grated chocolate over the top of the cream. Cover and refrigerate for up to 3 hours until serving.
