Creating Peanut Butter and Banana Overnight Oats is simple when you follow these easy steps:

1. Mash Bananas: In a medium bowl, mash the ripe bananas with a fork until smooth and creamy.
2. Mix Ingredients: Add rolled oats, milk, peanut butter, honey or maple syrup (if using), vanilla extract, and salt to the mashed bananas. Stir until everything is well combined.
3. Transfer to Jars: Spoon the mixture into individual serving jars or containers, filling each about three-quarters full to allow for expansion.
4. Refrigerate: Cover the jars with lids or plastic wrap and place them in the refrigerator. Allow them to chill for at least 4 hours or overnight.
5. Serve: In the morning, give the oats a good stir. Top with additional sliced bananas, chopped nuts, or granola if desired. Enjoy cold and straight from the fridge!

With these straightforward steps, you can whip up a nutritious breakfast that not only tastes good but also provides lasting energy for your day.
