Add the biscuits to a food processor and blitz until they are fine crumbs. Add the melted butter and blitz again till well mixed and the texture resembles sand. Evenly spread into the bottom of a 8 inch spring cake tin and press down. Rest in the fridge into whilst you make the filling.
Using an electric hand whisk, together the cream cheese and condensed milk till soft. Whisk in the double cream and vanilla until thickened. Evenly spread over the biscuit base. Drizzle over the melted chocolate and set in the fridge over night.
When ready to serve, decorate with the broken kinder eggs and bars by lightly pushing them in to the cheesecake where ever you fancy.
