Overnight oats with peanut butter are a quick and tasty breakfast! Just mix oats, milk, and peanut butter, then let them sit overnight in the fridge. In the morning, you’ve got a creamy treat!
I love how convenient they are! Just grab a jar, add your favorite toppings like bananas or honey, and you’re all set. Perfect for busy mornings when you need a yummy start!
Key Ingredients & Substitutions
Rolled Oats: These are the star of overnight oats! They absorb liquid and soften overnight. You can substitute with quick oats if you’re in a hurry, but they may be softer. Steel-cut oats are not recommended—they need more cooking time!
Peanut Butter: I love creamy peanut butter for its smooth texture, but chunky can add a nice crunch. If you’re nut-free, try sunflower seed butter or almond butter as great alternatives.
Milk: Any milk works! Dairy, almond, oat, or soy milk will do just fine. Coconut milk adds a fun flavor, but be careful—it can be richer, so adjust your sweetness!
Chia Seeds: These help thicken the oats and pack in nutrition. If you don’t have them, you can skip or replace them with ground flaxseeds. Both add extra fiber!
Sweeteners: Honey or maple syrup balance out the peanut butter’s richness. You could use agave syrup or leave it out if you prefer a less sweet flavor.
How Do I Make Sure My Overnight Oats Are Perfectly Creamy?
The key to creamy overnight oats is finding the right ratio of oats to liquid. Start with 1:1 for a thicker texture, or 1:1.5 if you like it smoother. Remember, they will thicken more as they sit!
- Combine ingredients in a jar, ensuring everything is mixed well.
- Seal tightly and refrigerate overnight.
- The next day, stir and add more milk if needed for consistency.
Also, don’t be afraid to get creative with toppings! Fresh fruits, seeds, or even a sprinkle of cinnamon can make your oats upscale and delightful. Enjoy your tasty breakfast!

Overnight Oats With Peanut Butter
Ingredients You’ll Need:
- 1/2 cup rolled oats
- 1/2 cup milk (dairy or plant-based)
- 2 tablespoons peanut butter (creamy or chunky)
- 1 tablespoon chia seeds (optional, for thickness)
- 1-2 teaspoons honey or maple syrup (optional, for sweetness)
- 1/2 ripe banana, sliced (for topping)
- A small handful of nuts or granola (for topping)
- Fresh strawberries (optional, for serving)
How Much Time Will You Need?
This recipe only takes about 10 minutes to prepare, then let it chill in your fridge overnight (or at least 6 hours). So, with just a little bit of prep time, you can have a delicious, nutritious breakfast ready to go in the morning!
Step-by-Step Instructions:
1. Mix the Ingredients:
In a mason jar or an airtight container, add the rolled oats, milk, peanut butter, chia seeds (if you’re using them), and honey or maple syrup (if you like it sweet). Stir everything well with a spoon until the peanut butter is thoroughly mixed in with the oats and milk.
2. Refrigerate Overnight:
Seal the jar or container tightly and place it in the refrigerator to chill overnight. This way, the oats and chia seeds can soak up the liquid and soften perfectly while you sleep.
3. Stir and Adjust Consistency:
The next morning, take the oats out of the fridge and give them a good stir. If they seem too thick, just add a splash of milk to loosen them up and mix until you reach your desired consistency.
4. Add Toppings:
Top your overnight oats with banana slices. If you’re feeling extra indulgent, drizzle on some more peanut butter! Then, sprinkle a handful of nuts or granola on top for that delightful crunch.
5. Serve with Fresh Fruits:
If you’d like, serve your oats with fresh strawberries on the side to add vibrant color and extra flavor to your meal.
6. Enjoy Your Delicious Breakfast!
Now, you can enjoy your creamy, satisfying peanut butter overnight oats cold! If you prefer it at room temperature, let it sit for a few minutes before diving in.
Can I Use Instant Oats Instead of Rolled Oats?
Yes, you can use instant oats, but they will yield a softer, mushier texture. If you prefer a firmer bite, stick with rolled oats!
How Do I Store Leftover Overnight Oats?
Store any leftover overnight oats in an airtight container in the fridge for up to 3 days. Just give them a good stir before eating, and add a splash of milk if needed!
Can I Make These Overnight Oats Vegan?
Absolutely! Simply use a plant-based milk like almond, oat, or coconut milk, and opt for maple syrup as your sweetener instead of honey. It’s easy to make them fully vegan!
What Are Some Good Toppings Besides Banana and Nuts?
Great question! You can use berries, sliced apples, or dried fruits like raisins and cranberries. A sprinkle of cinnamon or a scoop of yogurt can also elevate your overnight oats!
