Chop the mangoes into small pieces and blend them to a fine puree. In a bowl add in the full fat cream.
To the cream add in the condensed milk and then beat the cream such that it is almost thick and creamy.
Now add in the mango puree to the cram and fold gently such that the mango puree is evenly mixed to the cream. Transfer them to the serving bowl and refrigerate for 1 hour and then serve.
Notes
You can skip condensed milk if your mangos are more sweet
