something like a Mango Weis bar :
3 large very ripe bananas
2 large mangos
½ can condensed milk
½ tsp vanilla bean paste
Peel and cube the bananas and mangos into roughly ½ inch cubes; place in a single layer on a baking paper lined tray and freeze.
Place the frozen fruit in a food processor and process until smooth and creamy; you may need 2 batches, and to scrape the sides down a few times.
Line a deep tray or cake tin with baking paper and spread the frozen fruit mix to a depth of about 2 cm; freeze.
Whip the cream and condensed milk until stiff peaks form; spread in a thin layer over the frozen fruit mix and re-freeze.
Slice into small slices. Lie in a hammock. Eat. Yum.
