Key Ingredients & Substitutions
Rolled Oats: Rolled oats are best for this recipe, as they soak up moisture well. You can swap in quick oats for a softer texture or steel-cut oats for a chewier bite, but they’ll need longer soaking.
Milk: Use any milk you like—almond, oat, coconut, or cow’s milk all work. If you’re avoiding dairy, choose a nut milk or something creamy like oat milk for a rich taste.
Greek Yogurt: This adds creaminess and protein. If you avoid dairy, opt for a plant-based yogurt or skip it altogether. The oats will still be yummy!
Chia Seeds: These add a nice texture and thickening. You can leave them out if you prefer a smoother oats texture or replace them with flaxseeds.
Peanut Butter: My favorite for that classic taste, but you can use almond butter or sun butter if you’re nut-free. These alternatives provide a similar creamy texture.
Banana: The banana gives natural sweetness. If you don’t have a ripe banana, applesauce can be a good substitute for sweetness and moisture.
How Do You Properly Prepare Overnight Oats?
Making overnight oats is straightforward, but there are a couple of key steps to keep in mind. The main trick is balancing the liquid and oats so they’re not too dry or soupy.
- Mix the oats, milk, yogurt, chia seeds, peanut butter, sweetener, and vanilla in a jar. Stir well to ensure everything is well combined.
- Seal it and refrigerate. This resting time lets the oats absorb the liquid and soften to a creamy texture overnight.
- Don’t skip the toppings! Adding banana, nuts, and chocolate chips just before serving gives extra flavor and texture!
Enjoy them cold for a refreshing morning treat that’s both filling and nutritious!

Chunky Monkey Overnight Oats
Ingredients You’ll Need:
- 1/2 cup rolled oats
- 1/2 cup milk (dairy or any plant-based milk)
- 1/4 cup Greek yogurt (optional for creaminess)
- 1 tablespoon chia seeds
- 1 tablespoon peanut butter (plus extra for drizzling)
- 1 tablespoon maple syrup or honey
- 1/2 teaspoon vanilla extract
- 1 small ripe banana, sliced
- 1-2 tablespoons mini chocolate chips
- 2 tablespoons chopped walnuts
How Much Time Will You Need?
This recipe requires about 10 minutes of preparation time. After that, just pop it in the fridge and let the oats soak for at least 4-6 hours, or overnight for the best results. It’s the perfect make-ahead breakfast option!
Step-by-Step Instructions:
1. Combine the Ingredients:
In a jar or airtight container, add the rolled oats, milk, Greek yogurt (if using), chia seeds, peanut butter, maple syrup (or honey), and vanilla extract. Stir everything well until combined, making sure the oats are fully coated with the liquid.
2. Let It Soak:
Seal the jar or container tightly and place it in the refrigerator. You’ll want to let it chill for at least 4-6 hours, but preferably overnight. This resting time allows the oats to absorb the milk and soften beautifully!
3. Add Toppings:
When you’re ready to enjoy your overnight oats, take them out of the fridge. Slice your banana and layer it on top of the soaked oats. Sprinkle with chopped walnuts and mini chocolate chips for that extra crunch and sweetness!
4. Drizzle and Serve:
For an extra tasty treat, drizzle some peanut butter over the top. Now you’re ready to enjoy a delicious, creamy, and nutritious breakfast!
This Chunky Monkey Overnight Oats recipe is not only easy to make, but it’s also packed with flavor. It’s a delightful combination of creamy oats, banana, peanut butter, walnuts, and a touch of chocolate—perfect for busy mornings or a tasty snack!
Can I Use Instant Oats Instead of Rolled Oats?
Yes, you can! Instant oats will work, but be aware that they may become mushy if soaked too long. Consider reducing the soak time to 2-3 hours instead of overnight.
Can I Make This Recipe Vegan?
Absolutely! Simply use plant-based milk, skip the Greek yogurt, or use a dairy-free yogurt alternative. The recipe will still be delicious and creamy!
How Do I Store Leftovers?
If you have any leftovers, store them in an airtight container in the fridge for up to 3 days. Just give it a good stir before serving to redistribute any liquids.
Can I Add Other Toppings?
Definitely! Feel free to customize your oats with different toppings like berries, sliced almonds, or a sprinkle of cinnamon. Get creative with whatever you have on hand!
