Add the papaya, pineapple slices, almond milk and vanilla extract into the blender and blend for about 2 minutes.
Add a few ice cubes and blend again for about 10 seconds.
Pour into chilled glasses and serve.
Notes
If you prefer it sweeter you can add a tablespoon of brown sugar. Or If the smoothie is too thick for your taste you can add more almond milk to dilute it.
