In a mason jar (or other sealable container), mix together milk, chia seeds, maple syrup, and vanilla extract.
Let it sit for 5 minutes, then stir again to remove any clumps (don't skip this step - it's important!). Snap on a lid and refrigerate for 2+ hours.
Take a ripe mango and slice it into small chunks.
Throw them into a blender to blend until it turns into smooth puree consistency. Make sure to set aside a handful of mango chunks to use as toppings.
In a separate mason jar, scoop half of the chia pudding (that has now been refrigerated for 2+ hours) into the bottom of the jar, then scoop half of the mango puree on top.
Repeat again with the remaining chia pudding and mango puree for two more layers, so that you end up with 4 layers.
Add the mango chunks on top, then finish it off with a sprinkle of coconut flakes. Enjoy!
