In a medium bowl, mash the banana with a fork until mostly smooth.
Add the Greek yogurt, milk, maple syrup, and vanilla extract. Stir until well combined.
Fold in the rolled oats and chia seeds and mix until everything is evenly incorporated.
Cover and refrigerate for at least 4 hours, or overnight, until the oats are soft and the mixture has thickened.
In the morning, give it a good stir. If it's too thick, add a splash of milk to loosen it up.
Top with sliced banana, a drizzle of maple syrup, or any other toppings you like.
