Separate 100 ml of cream and warm until almost boiling. Stir in the instant coffee until melted. Set aside to cool down to room temperature (you can use an ice water bath).
Start whipping the rest of the cream and, when it starts to come together, pour in the coffee flavoured portion. Stop the mixer when it reaches hard peaks.
Fold in the condensed milk by gently incorporating it with upward motions with a spatula. Transfer mixture to a freezer safe container and let set for a minimum of 5 hours, or overnight.
