Combine the first 4 ingredients in a high-speed blender and blend for 30 seconds or until completely smooth. Pour into a container and stir in the chia seeds.
Cover, and place in the refrigerator for at least 15 minutes so the chia seeds absorb the cashew milk and the mixture becomes a creamy pudding. Alternatively, for a really pretty breakfast, you can also lay sliced fruit against the inside of individual glasses, then pour the chia pudding in. Let the puddings set in the fridge!
