Peanut Butter Overnight Oats are a quick and yummy way to start your day! Just mix oats, milk, and peanut butter, then let it sit overnight. Come morning, it’s ready to eat!
These oats are perfect for those busy mornings. I love adding some sliced bananas or a drizzle of honey—you can’t go wrong! Plus, it’s like having dessert for breakfast! 😋
Key Ingredients & Substitutions
Old-fashioned Rolled Oats: These are perfect for overnight oats because they absorb liquids well while still providing a nice chew. If you only have quick oats, you can use them, though the texture will be softer than rolled oats.
Milk: You can use any type of milk you like! Dairy, almond, soy, or oat milk all work. If you’re looking for more creaminess, full-fat coconut milk is a great alternative that adds a tropical flavor.
Peanut Butter: While creamy peanut butter is smooth and easy to mix, chunky peanut butter adds fun texture. If you’re allergic to peanuts, almond butter or sunflower seed butter offers delicious alternatives.
Chia Seeds: These are optional but help thicken the oats and add extra nutrition with fiber and healthy fats. You can skip them if you don’t have any or replace them with ground flaxseed.
Sweeteners: Honey or maple syrup are classic choices. If you prefer something low-calorie, try stevia, agave, or a sweetener like monk fruit to taste.
How Can I Make Sure My Oats Are Perfectly Creamy?
The key to creamy overnight oats is the right ratio of liquid to oats. Here are some tips:
- Make sure to stir everything well before refrigerating. This helps combine the peanut butter and milk properly.
- Adjust the milk amount based on how thick or creamy you like your oats. If you prefer a thicker consistency, use less milk.
- Let them soak overnight or for at least 4 hours. This allows the oats to absorb the liquid fully and soften up.
- In the morning, give the oats a quick stir. If they’re too thick, just mix in a splash of milk for your desired creaminess.
These simple steps will help you achieve a satisfying and creamy bowl of overnight oats every time!

How to Make Peanut Butter Overnight Oats
Ingredients You’ll Need:
- 1/2 cup old-fashioned rolled oats
- 1/2 cup milk (dairy or plant-based such as almond, soy, or oat milk)
- 3 tablespoons peanut butter (creamy or chunky)
- 1 tablespoon chia seeds (optional, for thickness and nutrition)
- 1 tablespoon honey or maple syrup (adjust to taste)
- 1/4 teaspoon vanilla extract (optional)
- Pinch of salt
- Fresh blueberries for topping
- Extra peanut butter for drizzling

How Much Time Will You Need?
This tasty breakfast takes just about 10 minutes to prepare! The real magic happens overnight in the fridge. You’ll have to wait at least four hours, but it’s well worth it for a grab-and-go meal in the morning!
Step-by-Step Instructions:
1. Combine Ingredients:
In a medium-sized jar or bowl, combine the rolled oats, milk, peanut butter, chia seeds (if using), honey or maple syrup, vanilla extract, and a pinch of salt. Mixing these ingredients together will bring out the delicious peanut butter flavor!
2. Mix It Up:
Using a spoon or a whisk, stir well until the peanut butter is mostly incorporated and the mixture is evenly combined. You want all the oats to be coated in that yummy peanut butter goodness!
3. Refrigerate Overnight:
Cover the jar or bowl with a lid or plastic wrap and refrigerate overnight (or at least 4 hours). This waiting period is essential—it allows the oats to soak up the milk and become soft and creamy.
4. Stir in the Morning:
When you’re ready to eat, take the oats out of the fridge and give the mixture a good stir. If it feels a bit too thick, don’t worry! Just add a splash of milk to reach your desired consistency.
5. Add Toppings:
Top your delicious oats with fresh blueberries, a drizzle of extra peanut butter, roasted peanuts, and a sprinkle of a few oats for fun texture. Feel free to get creative with your toppings!
6. Enjoy!
Serve your Peanut Butter Overnight Oats chilled and enjoy a creamy, nutty, and satisfying breakfast that will keep you full and happy all morning long!
This recipe makes one generous serving that perfectly captures the spirit of the luscious peanut butter swirl and delightful toppings like in the image. Enjoy your delicious creation!
Can I Use Instant Oats Instead of Rolled Oats?
Yes, you can use instant oats, but keep in mind that the texture will be softer and creamier. If you prefer a bit of chewiness, rolled oats are the best choice!
How Long Can I Store Leftover Oats?
These overnight oats can be stored in the fridge for up to 3 days. Just make sure to keep them in an airtight container. You may need to stir in a little milk before eating if they thicken up too much.
Can I Customize the Sweetness?
Absolutely! Feel free to adjust the amount of honey or maple syrup to suit your taste. If you like it sweeter, add more, or if you prefer less sweetness, use less or try adding fresh fruit instead.
What Other Toppings Work Well?
You can get creative with toppings! Sliced bananas, chopped nuts, seeds, shredded coconut, or even a dollop of yogurt would be delicious. Experiment with your favorites!
