Mix chia seeds and oat milk. Let sit for at least an hour in the fridge.
Add banana, vanilla extract, maple syrup, and salt. Mix in a Nutribullet or high speed blender for a creamy consistency, or by hand for a textured consistency. If you let it sit in the fridge overnight, it will get even thicker.
Top with sliced banana.

Notes
Chia pudding will last about 4-5 days in the fridge. If I have leftover chia pudding and am not in the mood for it, I will add it to my morning smoothie to use it up.
