Prep the pudding the night before you plan to assemble the parfaits. Combine the almond milk, chia seeds, maple syrup, and cinnamon in a storage container and whisk thoroughly. Place in the fridge overnight (or for 5-7 hours minimum) to let the chia seeds expand and work their magic.
For the avocado mousse, combine avocado, almond milk, cacao powder, and maple syrup in a blender (I like to use my Nutribullet because it's nice and small) and blend for 30 seconds until smooth and creamy.
Layer the ingredients between 4 small glass jars (I linked the Weck jars that I used for these above!), starting first with the chia pudding, then the mousse, a few berries, then repeat. Enjoy! These can be stored in the fridge for up to 4 days.
