In a blender, combine the thick part of the coconut cream, macadamia nuts, shredded coconut vanilla, soy milk, and maple syrup. Blend until smooth and creamy. Taste and add additional sweetener.
Transfer to ice cube tray by pouring the blended mixture into ice cube trays. Fill each compartment to the top, but don't overflow. Place the ice cube tray in the freezer and let it freeze until solid, which usually takes about 4-6 hours or overnight.
Once the coconut milk mixture is frozen solid, take the ice cube tray out of the freezer and let it sit at room temperature for a few minutes to slightly thaw. Transfer the frozen cubes into a blender or food processor. Pulse a couple of times then blend until the mixture becomes soft and crumbly. You may need to stop and scrape down the sides of the blender or food processor a few times to ensure everything is well mixed.
Once the mixture is smooth and creamy, you can serve the coconut ice cream immediately as soft-serve. Although it might look crumbly you can test it by using an ice cream scoop. If you over blend it transfer it to a container and freeze it for a firmer texture.
