Combine the chia seeds, coconut milk, milk, maple syrup and vanilla extract in a small dish or jar and whisk well.
Cover and refrigerate for at least 3-4 hours or overnight. Use a whisk or fork to mix again to break up any large clumps. You can add a couple extra tbsp of milk before serving if the consistency gets too thick.
Divide into two portions and serve with a scoop of yogurt, coconut flakes and cubed mango.
