Place the coconut milk, frozen pineapple juice cubes, pineapple flavoring, ice and rum (if using) into a blender.
Puree or Pulse mixture until thick and creamy, and ice has been pulverized.
Pour into a glass and serve immediately.
Notes
This drink is best made with full-fat coconut milk in a can.
The pineapple flavoring does not come with a dropper. Simply stick the tip of a straw into the bottle. Place your finger on the other end to create suction, then release your finger and drop the flavoring into the blender.
