Peanut Butter Banana Overnight Oats are the best way to get going in the morning. It is so quick and easy to combine rolled oats, creamy peanut butter, bananas, maple syrup, and milk in a Mason jar and let the fridge do the work.

Meal Prep and Storage

    • To prep and store: It is so simple to prepare this dish entirely the evening before. Once it's mixed, it will stay in the fridge in an airtight, resealable container for up to 3 to 4 days. However, after the first 24 hours, the oatmeal will get mushy. You can prep extra by waiting to mix the milk in until the night before you serve it.
    • To freeze: Freezing is not recommended.  The texture of the oats will not be the same and instead will be too watery.
