I'm going to hand you over to Mrs.C-flat who will give you the recipe..................
Go Girl!

make a biscuit crumb base and press into a flan dish, chill in refrigerator.
Put a can of condensed milk into boiling water and simmer for 2 hours. Leave to cool then spread over biscuit base.
Top with sliced banana followed by whipped cream.
Finish with lots of grated chocolate.

Thank you dear...Yes that will be all...

Enjoy
