Put chia seeds, coconut milk, cocoa powder, maple syrup, vanilla extract, and sea salt in mixing bowl or large mason jar and stir to combine, making sure to break up any clumps of cocoa powder.
Let chia seed pudding "set" in refrigerator for at least two hours.
After setting time, if Chia Pudding is too thick, stir in extra coconut milk 1 tablespoon at a time until you get the consistency of pudding.
Spoon chia pudding into serving bowls or cups and top with optional garnishes.
