Prepare chia pudding (2nd layer) first.
Put chia seeds and cashew milk in a bowl and mix well.
Place in the refrigerator for a few hours or even overnight to allow to thicken.
After chia pudding has set, place mango, banana and cashew milk in blender.
Blend until semi-smooth (I like little chunks) or until your desire consistency.
Pour into 2 glasses, reserving a small amount.
Pour chia pudding on top.
Add remaining mango mixture on top of both puddings.
Sprinkle with coconut if desired.
