Key Ingredients & Substitutions
Rolled Oats: Rolled oats are ideal for this recipe as they soak up the liquid nicely overnight. If you want a quicker option, you could use instant oats, but they may become mushy. For a gluten-free version, opt for certified gluten-free oats.
Milk: You can use any type of milk, bee it cow’s milk or plant-based alternatives like almond, soy, or oat milk. Each type will change the flavor slightly, so go with what you enjoy best.
Banana: A ripe banana adds natural sweetness. If you don’t have bananas, you could use applesauce or even mashed avocado for a creamy texture, though the flavor will vary.
Peanut Butter: Creamy peanut butter is my favorite, but feel free to swap it with almond butter, sunflower seed butter, or any nut/seed butter you like! Just make sure it’s smooth for easy mixing.
Chia Seeds: They’re optional, but I love adding them for extra nutrition. You can substitute them with ground flaxseeds, which also add a nice boost of fiber.
How Do I Get the Right Texture for Overnight Oats?
The texture of overnight oats is crucial for a great breakfast. Here’s how to get it just right:
- Start with the right ratio of oats to liquid. For creamy oats, stick to 1/2 cup of oats and 1/2 cup of milk.
- Mix all ingredients thoroughly so each oat gets soaked properly.
- Let it sit overnight in the fridge. This helps the oats absorb the liquid and soften without cooking.
- If you prefer it creamier in the morning, simply stir in a little more milk until it reaches your desired consistency.
By following these steps, you’ll achieve the perfect creamy oats every time!

Banana Peanut Butter Overnight Oats
Ingredients You’ll Need:
- 1/2 cup rolled oats
- 1/2 cup milk (dairy or plant-based)
- 1/2 medium ripe banana, sliced
- 2 tablespoons peanut butter
- 1 tablespoon chia seeds (optional)
- 1/2 teaspoon vanilla extract
- 1 teaspoon honey or maple syrup (optional)
- Pinch of salt
- Sliced banana, chopped peanuts, and extra chia seeds for topping
How Much Time Will You Need?
This recipe takes about 10 minutes of prep time. Then, just let it chill in the refrigerator overnight or for at least 4 hours. When you wake up, breakfast is ready to enjoy!
Step-by-Step Instructions:
1. Combine the Base Ingredients:
In a clean jar or bowl, mix together the rolled oats, milk, chia seeds (if you’re using them), vanilla extract, honey or maple syrup (if you want sweetness), and a tiny pinch of salt. Stir everything well until it’s nicely combined.
2. Add Banana:
Gently fold in half of your sliced banana into the oat mixture. This adds nice flavor throughout!
3. Refrigerate:
Seal your jar or cover your bowl tightly and pop it in the fridge. Let the oats soak overnight (or at least for 4 hours) to allow them to soften and absorb all that delicious flavor.
4. Stir and Adjust:
When you’re ready to eat in the morning, take your oats out of the fridge and give them a good stir. If you like your oats a bit thinner, add a splash more milk and mix until it’s just how you like it!
5. Top with Peanut Butter:
Spoon the peanut butter over the top of your oats. Don’t be shy—this is where the creamy goodness comes from!
6. Add More Banana and Toppings:
Layer the remaining banana slices on top of the peanut butter. Then, sprinkle on some chopped peanuts for crunch and a few extra chia seeds if you’re feeling fancy!
7. Serve:
Your Banana Peanut Butter Overnight Oats are all set! You can enjoy them chilled straight from the fridge or let them sit for a few minutes at room temperature. Dig in and enjoy your creamy, sweet, and nutritious breakfast!
Can I Use Instant Oats Instead of Rolled Oats?
Yes, you can use instant oats, but they may absorb liquid differently and could become mushy. If you prefer a chewier texture, rolled oats are the way to go!
How Long Do Leftovers Last?
Leftover overnight oats can be stored in the fridge for up to 3 days. Just make sure to keep them in an airtight container to maintain freshness.
Can I Make This Recipe Vegan?
Absolutely! Simply use a plant-based milk (like almond or oat milk) and maple syrup instead of honey for a completely vegan-friendly dish!
What Can I Add for Extra Flavor?
Feel free to get creative! Adding cinnamon, nutmeg, or even a scoop of protein powder can boost the flavor and nutrition. Dried fruits or nuts make great mix-ins as well!
