Preheat the oven to 375ºF. Coat a 1 ½ quart baking dish with cooking spray.
In a large bowl, whisk together almond milk, almond butter, maple syrup, vanilla extract, and salt. Add the oats and stir to combine. Transfer to the prepared baking dish and smooth out the top.
Bake 35 minutes or until set in the middle and beginning to brown around the edges. Serve immediately with an extra splash of almond milk and sliced bananas if desired.

Notes
If you only have a larger dish, reduce the baking time by 5 minutes.
