01 - Combine coconut milk, coconut cream, sugar, and salt in a medium saucepan. Heat over medium heat, stirring constantly, until sugar dissolves completely, about 3-5 minutes. Avoid boiling the mixture.
02 - Remove saucepan from heat. Stir in vanilla extract until fully incorporated.
03 - Let mixture cool to room temperature. Refrigerate until thoroughly chilled, at least 2 hours.
04 - Pour chilled mixture into ice cream maker. Churn according to manufacturer instructions, typically 20-25 minutes, until soft-serve consistency forms.
05 - Gently fold toasted coconut flakes, chopped peanuts, or diced mango into churned ice cream until evenly distributed.
06 - Transfer ice cream to freezer-safe container with lid. Freeze for at least 2 hours until firm enough to scoop.
07 - Let ice cream sit at room temperature 5-10 minutes before scooping. Serve plain or with additional toppings.
