In a small bowl or jar, combine oats, chia seeds, cinnamon, almond milk, and vanilla. Cover and chill in refrigerator overnight, at least 8 hours.
Before serving, microwave sliced bananas and peanut butter in a small microwave-safe bowl for 20 seconds, or until bananas are soft and peanut butter is melted. Add to chilled oats.
Drizzle in maple syrup and top with pecans; stir until combined. Enjoy!
