Pour pineapple juice, coconut cream, light rum, and one cup of crushed ice into a blender.
Blend until smooth and creamy with no chunks.
If desired, add more ice and blend again for a thicker drink.
Pour into chilled glass and garnish with pineapple wedge or cherry.
Notes
For a mocktail version, simply omit the rum. Serve in a chilled glass for best texture and flavor. Freeze leftover mix in cubes for later use in smoothies or drinks.
