Add all the ingredients to a blender and blend together until thick and smooth. Alternatively, blend the fruit first and add the heavy cream at the end.
Serve immediately.
Store covered in the fridge for up to one day*
Notes
- If using frozen fruit, let it stand for a while so the fruit can thaw. It's easier to blend that way. If you have a very powerful blender, you can also blend frozen.* Note: the smoothie is best served on the same day.
