Add pineapple, coconut milk and maple syrup (if using) to a blender or food processor.
Blend until smooth, scraping down the sides of the blender as needed.
Pour into a freezer-friendly, airtight container. Freeze for 3-6 hours, or until completely frozen. Allow to thaw for 10-50 minutes before scooping—this treat can take awhile to thaw.** Enjoy!
*Do not chill coconut milk. Use room temperature canned coconut milk. Shake well to mix. Best when completely liquidy.
**To quickly thaw, first ensure that ice cream is in a microwave-safe container. Microwave in 15-second increments until slightly soft and scoopable.
Storage Instructions: Store in an airtight container in the freezer. Best the first day. Before serving, allow to thaw for about 15-40 minutes. Scoop and enjoy!
