Peanut butter overnight oats are so yummy I could eat them everyday. This easy, healthy breakfast recipe is literally only 2 ingredients: peanut butter and oats.  Made without milk and has no chia seeds. It takes only 5 minutes to prep. It's vegan, gluten-free, dairy-free and sugar-free. You can prep ahead and keep it in the refrigerator for up to a week for a quick, grab-and-go breakfast throughout the week.



1/3 cup "Old Fashioned" rolled oats

2 tablespoons smooth, salted peanut butter, no sugar added

1/3 cup water

Toppings Optional:

Depending on your carb budget, you can add frozen fruit, fresh fruit, nuts and seeds. You may also use your favorite spices.


In an 8 ounce mason jar combine dry oats with peanut butter. Combine throughly. It helps to use chopsticks or a dinner knife to mix the oats and peanut butter together. Mix in water. Seal with lid and place in refrigerator overnight.
