Kori's tips.
- Use ripe bananas. The riper the bananas, the sweeter and more flavorful your overnight oats will be.
- Stir the peanut butter first. Natural peanut butter separates, so give it a good stir before measuring for the creamiest texture.
- Adjust the consistency. If the oats are thicker than you like after chilling, stir in a splash of almond milk before serving.
- Portion them out. Divide the mixture into individual jars right away for easy grab-and-go breakfasts during the week.
- Make them your own. Change up the toppings or mix-ins to keep breakfast interesting without making a whole new recipe.
