In a bowl or glass jar, whisk together the milk and protein powder until no clumps remain.
Stir in the chia seeds, maple syrup, and coconut extract, and allow the mixture to sit for 15 minutes undisturbed. After 15 minutes, stir again, cover, and place in the fridge for 8 hours or overnight.
Before serving, puree your ripe mango until smooth.
To a mason jar, add a layer of the chia pudding, followed by a layer of the mango puree. Repeat these layers again, then end with a final layer of chia pudding.
Serve garnished with toasted coconut and/or fresh mango chunks if desired. Serve!
