In a medium bowl, combine the coconut milk, almond milk, maple syrup, vanilla extract, and a pinch of salt. Whisk until well blended.
Stir in the chia seeds, ensuring they are evenly distributed. Cover the bowl and refrigerate for at least 4 hours or overnight, allowing the chia seeds to expand and thicken the mixture.
After the chia pudding has set, give it a good stir to break up any clumps that may have formed.
To serve, layer the chia pudding in small cups or bowls. Start with a layer of chia pudding followed by a layer of diced mango, and repeat until you reach the top.
Top with shredded coconut and garnish with fresh mint leaves for a pop of color and freshness.
