01 - In a medium bowl, whisk together the coconut milk, chia seeds, maple syrup, vanilla extract, key lime zest, and key lime juice until thoroughly combined and no dry pockets remain.
02 - Allow the mixture to rest for 5 minutes, then whisk again vigorously to break up any chia seed clumps that may have begun forming.
03 - Cover the bowl tightly and refrigerate for at least 2 hours or overnight, allowing the chia seeds to fully hydrate and the pudding to thicken into a creamy, spoonable consistency.
04 - Give the pudding a final stir to ensure uniform texture, then spoon into individual serving glasses or bowls.
05 - Dollop coconut yogurt over each portion, sprinkle with crushed graham crackers, and finish with a few key lime slices or a dusting of extra zest.
