Peanut Butter Overnight Oats are an easy meal prep breakfast you'll love. They take just minutes to prepare and are ready to eat straight from the fridge.
In a 12-ounce or larger glass jar, combine the rolled oats, flax, peanut butter, maple syrup, and milk. Stir well to mix.
Secure a lid on the jar, then place it in the fridge to chill overnight. You can make this up to 3 days in advance, so feel free to double or triple the recipe to make more jars at once.
In the morning, take the lid off the oats and stir well. Add any toppings you like, such as fresh fruit or an extra drizzle of peanut butter. These oats are ready to eat right away.
