Combine all ingredients in a high speed blender (or food processor).
Blend until smooth and creamy, about 2-3 minutes.
If you want that iconic soft serve look: Put the mixture into a pastry bag with star tip or plastic bag and put in fridge/freezer for about 5 minutes to chill.
Pipe into serving dish or waffle cone and enjoy!
Optional: Garnish with fresh pineapple.
Notes
For best results freeze the fruit in airtight containers
