In a bowl, add the condensed milk and cream. Peel the mangoes and either slice them roughly or cut them into cubes.
Mix it nicely with a spoon. Open the Graham crackers. For my Singapore readers, these graham crackers i got from Fair price.
In a square glass bowl or a pan (i used my cake pan) arrange the biscuits in one layer first.
Pour the cream and condensed milk over that as a layer. Spread it evenly.
Add the sliced or cut mangoes on top as a layer. Meanwhile, crush 2-3 biscuits and smear them on the top.
Now arrange one more layer of biscuits on this and repeat the same procedure. The cream condensed milk mixture came in 2 thin layers.
Cover this with cling film or aluminum foil, then refrigerate for 6 hours or overnight.
Slice this and serve it chilled.
