01 - In a medium mixing bowl, whisk together the coconut milk, chia seeds, maple syrup, vanilla extract, key lime zest, and fresh key lime juice until thoroughly combined and smooth.
02 - Allow the mixture to rest for 5 minutes, then whisk again vigorously to break up any chia seed clumps and ensure even distribution throughout the liquid.
03 - Cover the bowl tightly and refrigerate for at least 2 hours or overnight, allowing the chia seeds to fully absorb the liquid and the pudding to thicken to a rich, creamy consistency.
04 - Remove from the refrigerator and stir the pudding well to loosen the texture. Spoon into individual serving glasses or bowls, dividing evenly among four portions.
05 - Top each serving with a dollop of coconut yogurt, a sprinkle of crushed graham crackers, and additional lime zest or thin lime slices for a bright, finished presentation.
