In a bowl, add the condensed milk and the lime, mix it all together very well, until fully combined.
In a glass dish, make the first layer of the dessert with this cream, the second layer with the cookies and repeat this process until you top it all with a layer of cream.
Let it chill in the fridge for at least 3 hours to make the cream firm and to moisten the cookies.
Crush some of the cookies and sprinkle the crumbs all over the dessert, passing them through a sieve.
Serve.
