Combine all of the ingredients in a blender, and blend until a uniform texture is achieved. Transfer to a sealed container and allow to chill overnight.
Serve with a sliced banana and a dash of cinnamon, if desired.
If you prefer a tapioca-like texture, simply stir all of the ingredients together and allow to chill overnight. Chia puddings take practice to get the texture "just right," so feel free to adjust the amount of seeds or liquid to achieve the texture you desire.
