01 - In a medium mixing 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 at room temperature, then whisk vigorously a second time to break up any chia seed clumps that may have begun forming.
03 - Cover the bowl tightly with plastic wrap and transfer to the refrigerator. Chill for a minimum of 2 hours or overnight until the pudding reaches a thick, creamy consistency.
04 - Remove from the refrigerator and give the pudding a final stir. Spoon evenly into four serving glasses or bowls.
05 - Top each portion with a dollop of coconut yogurt, a sprinkle of crushed graham crackers, and extra lime zest or thin lime slices. Serve immediately while chilled.
