Mix it up: In a jar or container, combine oats, maple syrup, vanilla, peanut protein powder and plant milk.
Stir well: Mix until fully combined and smooth. It may look a bit runny at first, but the oats will absorb the liquid overnight.
Refrigerate: Cover and refrigerate overnight (or at least 4 hours). By morning, it will be thick, creamy, and ready to eat.
Top and enjoy: Add a scoop of peanut butter and chopped bananas or other fruit. Enjoy!
