Combine the coconut milk, non-dairy milk, chia seeds, cacao, coconut sugar or maple syrup and sea salt in a blender. Blend on high, until the chia seeds are completely incorporated and the mixture is very smooth.
Pour into a medium bowl, cover, and refrigerate until cold, about 2 hours.
Portion the mixture into individual containers if desired, then store, covered, in the fridge for up to 5 days.
When ready to serve, top with berries, cacao powder, and/or cacao nibs and serve.
