Whisk the sweetened condensed milk, liqueur, cocoa powder, and salt in a bowl until combined.
In a separate bowl, whip the heavy cream until soft peaks form.
Gently fold all the whipped cream in the cocoa mixture.
Pour the mixture in a freezer-safe container and let it freeze overnight.
Serve it as soon as you pull it out of the freezer — it will be nice and scoopable.
Don’t let it sit at room temperature for too long, it will start melting fast.Recipe from Food52
