Place the frozen pineapple and coconut milk into a food processor or high-powered blender.
Turn on the food processor and blend until the consistency becomes creamy. You might have to stop several times and scoop down the pineapple.
Keep blending until all of the pineapple chunks are gone and the mix is smooth.
Enjoy immediately as it is ‘soft serve’ and should be eaten straight away.
If you want to freeze a little you can, just know it does freeze solid once frozen and is no longer soft.
