Add oats and unsweetened almond milk to a small bowl or jar.
Stir in maple syrup. Stir in peanut butter but not too well. It's nice to have chunks throughout. Stir in granola.
Using a spoon make sure oats are submerged in liquid. Cover with saran wrap or a lid.
Refrigerate overnight. Enjoy in the morning. Top with more peanut butter and granola if desired.
