Add the frozen pineapple chunks, coconut milk, frozen banana, shredded coconut, honey (if using), vanilla extract, and sea salt to a high-speed blender.
Blend on high speed for 60-90 seconds, stopping to scrape down the sides if needed, until completely smooth and creamy with no ice chunks remaining.
Check the consistency — if too thick, add coconut milk 1-2 tablespoons at a time and blend briefly until you reach your preferred texture.
Taste and adjust sweetness if needed by adding more honey or a squeeze of lime juice for extra tang.
Pour immediately into two chilled glasses and serve right away, or transfer to an airtight container for storage.
