Start by making the chia seed pudding by mixing all the ingredients in a large flat container or bowl. Mix a few times every 5 minutes while making the remaining ingredients. Set aside. It should start to thicken up within 20 minutes.
TIP: You can refirgerate this overnight if prefered.
Meanwhile, in a medium bowl, mix the Chocolate Yogurt ingredients together.
In another small bowl, mash 3 bananas.
Grab 4 containers, add a layer of the mashed bananas. Then add a layer of the chocolate yogurt. Then add a big layer of the chia pudding. Top with sliced bananas and enjoy.
TIP: you can make ahead the chia seed pudding and the chocolate yogurt and refrigerate them overnight. When you're ready to serve, then mash/slice the bananas and assemble.
