In a medium mixing bowl, whisk together the coconut milk, Greek yogurt, vanilla extract, cinnamon, and maple syrup until smooth.
Add the chia seeds and whisk well to combine.
Let the mixture sit for 5 minutes, then whisk again to break up any clumps.
Cover and refrigerate for at least 4 hours, or overnight, until thick and creamy.
Stir before serving and divide into jars or bowls.
Top with fresh fruit, granola, or shredded coconut if desired.
