Throw the coconut milk, maple syrup, vanilla, cinnamon, and salt into your blender, and blast on high for 10 to 20 seconds until smooth. Transfer this mixture to a glass bowl or large jar and stir in the chia seeds until well combined.
Chill in the fridge for at least 3 hours stirring occasionally to evenly distribute the chia seeds.
Once chilled, stir the mixture again, and add in 1 mashed banana.
Transfer the mixture to 4 serving bowls and top with chopped banana and shredded coconut.
