No sugar or any other sweetener is used in this recipe because the sweetness from the mango and banana adds just the right amount of sweetness to the smoothie.
Place the milk, frozen mangoes, frozen banana, and greek yogurt into your blender (always remember to add your liquid first into the blender, that will help your blender to run a little more smoothly).
Blend until completely smooth and creamy.
Pour into 2 large glasses, garnish with some mint leaves, pop in a straw and serve.
Notes
You can use fresh mangoes and banana instead of frozen, just add a handful of ice cubes to your blender in that case. So the smoothie will still be nice and thick and cold.
