Add the chia seeds and milk (along with optional sweeteners) to a bowl or jar and stir together. Let sit for 10 minutes, then stir again once the seeds have started to gel.
Cover the bowl or jar and place in the refrigerator for at least one hour. Chia seeds can also be made overnight for breakfast the next morning.
Stir the chia pudding before serving and add your favorite fruit, nuts, seeds and spices.
