Measure out 1 cup of rolled oats and 1 1/2 cups of plant-based milk.
Mash 1 ripe banana in a separate bowl.
Warm 2 tablespoons of peanut butter if it’s too thick to stir easily.
Combine the mashed banana, rolled oats, and plant-based milk in a jar or container with a tight lid.
Add 2 tablespoons of chia seeds to the mixture.
Stir in 1/2 teaspoon of vanilla extract and 1/2 teaspoon of cinnamon.
Add 2 tablespoons of maple syrup or agave nectar if you like it sweet.
Mix all ingredients thoroughly.
Seal the jar or container with the lid.
Refrigerate overnight.
Enjoy your overnight oats in the morning.
