In a mixing bowl, mash 2 large ripe bananas until mostly smooth (you can leave a few small chunks if you prefer).
Add 3 Tbsp unsweetened almond butter to the mashed bananas and stir until well combined.
Pour in 2 cups unsweetened almond milk (or milk of choice), add 1 tsp pure vanilla extract, and 1–3 Tbsp pure maple syrup or honey if using; stir until the liquid ingredients are fully incorporated.
Add 2 cups gluten-free rolled oats, 1/2 tsp ground cinnamon, 1/4 tsp sea salt, and 2–4 Tbsp protein powder if using; stir until the oats and seasonings are evenly distributed.
Transfer the mixture to an airtight container or divide into individual jars (a 1-quart mason jar works well) and seal. Refrigerate for at least 3 hours or overnight to thicken.
Store the prepared overnight oats in the refrigerator in an airtight container for up to 4 days.
Just before serving, give the oats a good stir. If desired, add a splash of non-dairy milk, extra maple syrup or honey to taste, and toppings such as almond butter, hemp seeds, and fresh fruit.

Notes
If you are not gluten-sensitive, you can also use regular rolled oats. Just be sure you don't use quick or instant oats for the best texture.
