Blend the diced mangoes until smooth. If you prefer, you can strain the puree to remove any fibrous bits for a softer texture.
Combine the heavy cream, whole milk, sugar, vanilla extract, and a pinch of salt in a large mixing bowl. Whisk until the sugar is fully dissolved.
Stir the mango puree into the cream mixture until well combined. Cover the mixture and refrigerate for at least 2 hours, or until thoroughly chilled.
Pour the chilled mixture into an ice cream maker and churn according to the manufacturer’s instructions, usually around 20-25 minutes, until it reaches a soft-serve consistency ( you can also use the mango-shaped silicone mold).
Transfer the churned ice cream to a lidded container and freeze for at least 4 hours, or until firm.
Scoop the ice cream into bowls or cones, and garnish with mint leaves or a squeeze of lime juice for a refreshing twist.
