Overnight oats are a type of no-cook oatmeal. You mix dry and wet ingredients to soak together overnight. Even without microwaving or boiling the oatmeal, it becomes soft overnight. Great option for breakfast meal prep!
On the weekend you can find me in my kitchen making pancakes or zucchini casserole, but when I want a make-ahead breakfast, overnight oats are a go-to.
My base recipe is adapted from Eating Bird Food without the chia seeds. Next, try protein powder overnight oats and Nutella overnight oats.

Ingredients
Peanut butter overnight oats call for a few ingredients you may already have on hand.
- old fashioned oatmeal - Note, this is different from instant oats or quick oats.
- almond milk - Or your milk of choice! I love cow's milk or plant-based milk like almond milk, coconut milk, or soy milk.
- plain Greek yogurt - You could also use vanilla yogurt or nonfat yogurt.
- creamy peanut butter - Creamy peanut butter is easier to stir than chunky peanut butter.
- honey - For sweetness. You could also use maple syrup or brown sugar.
- vanilla extract - To add a light touch of vanilla flavor.
- salt - To bring out the peanut butter.
- cinnamon - Just a pinch.

Instructions
Add all of the ingredients to a 12 oz or 16 oz jar or bowl and stir to combine until peanut butter is completely incorporated.
The mason jar pictured is a 12 ounce mason jar.
Cover and refrigerate overnight or a minimum of four hours.
Remove from the fridge the next morning, stir the oatmeal, and serve.
I prefer cold oats, but if you prefer hot oatmeal you can warm it in the microwave. Heat in 30-second intervals and stir.
Topping Ideas
I always like to add a few toppings to my overnight oats for a little crunch. My favorite toppings are peanuts (chopped or whole), granola, and chocolate chips.
For an extra peanut butter punch, add a drizzle of peanut butter to the top. And of course, peanut butter goes well with fresh fruit like strawberries or bananas.
Substitutions
Here are a few ways to personalize your peanut butter overnight oats to make them your own.
- Milk - Use any type of milk you like. I keep unsweetened vanilla almond milk on hand, so that's what I like to use. Oatmeal is a carb-heavy breakfast as it is, so I avoid dairy milk which has more sugar than you would expect. For this reason, I also don't use oat milk.
- Nut butter - This recipe would be tasty with any nut butter (almond butter, sunflower seed butter, cashew butter, you name it!). You can also use peanut butter powder.
- Honey - I use honey because peanut butter and honey just make sense to me, but you can also use pure maple syrup, agave nectar, or brown sugar (same amount).
Equipment
With all of the ingredients combined, the volume in my mason jar measures a little under 10 ounces. I use a 12 oz jar in my photos. This gives you plenty of room to stir and add extra toppings.
If you plan to increase the serving size or add lots of toppings, you'll have more room in a 16 oz wide-mouth mason jar for overnight oats. Generally, this is my go-to size.
I prefer a wide-mouth jar because it's easier to get your spoon in and out of the jar to mix the ingredients. With the peanut butter, you definitely want some wiggle room because you have to mix a lot. You could also use a bowl and cover it with cling wrap.
Storage
Store leftovers in the fridge in an airtight container. Good for up to 4 days.

Topping with peanuts is a must for that added crunch.
