Chunky Monkey Overnight Oats are a fun and tasty way to start your day! Packed with oats, ripe bananas, and a touch of chocolate, they’re super easy to make.
I love preparing these oats the night before. Just mix everything and let it sit in the fridge. In the morning, I have a delicious breakfast ready and waiting. So convenient!
Key Ingredients & Substitutions
Rolled Oats: These are the base of your overnight oats. If you want a quicker option, instant oats work too, but they may become mushier. Steel-cut oats take longer to soak, so be sure to plan ahead if you go that route.
Chia Seeds: They help thicken the oats. If you don’t have chia seeds, you can skip them, but they add a nice texture and a source of healthy omega-3s. Flaxseeds are another great option if you have those instead.
Milk: Use any milk you like, whether it’s cow’s milk, almond, oat, or coconut. If avoiding dairy, almond or oat milk are my go-to options.
Banana: Ripe bananas provide natural sweetness and creaminess. A few slices on top make it look pretty, plus an extra layer of flavor. If bananas aren’t your thing, consider using applesauce or diced mango.
Peanut Butter: I prefer creamy peanut butter for a smooth texture, but crunchy peanut butter works too! For nut-free options, use sun butter or another seed butter.
What’s the Best Way to Prepare Overnight Oats?
Making overnight oats is straightforward, but a few tips can make all the difference. Start by mixing the dry ingredients like rolled oats and chia seeds in a bowl or jar. Then, add your wet ingredients like milk and vanilla.
- When mashing the banana, a fork works well to mash it smoothly before adding to the mixture.
- Stir everything thoroughly to ensure even distribution of flavors. The oats should be fully coated in the liquid.
- Refrigerate overnight. This step is key for the oats to soften and the chia seeds to thicken the mix.
- In the morning, give it a good stir. If it’s too thick, add a splash more milk to loosen it up.

Step-by-Step Instructions:
1. Combine Dry Ingredients:
In a medium bowl or jar, mix together the rolled oats, chia seeds, and a pinch of salt. This creates a great base for your overnight oats!
2. Add Wet Ingredients:
Pour in the milk and add the vanilla extract. If you like things a bit sweeter, add the maple syrup or honey now. Stir well to combine everything.

Can I Use Instant Oats Instead of Rolled Oats?
Yes, you can! Instant oats will absorb liquid faster and result in a creamier texture. Just keep in mind they may become mushy if left too long, so consume them within a day.
How Can I Make This Recipe Vegan?
To make this recipe vegan, simply use plant-based milk such as almond, soy, or oat milk, and choose maple syrup instead of honey. Everything else is already vegan-friendly!
What If I Don’t Have Chia Seeds?
No worries! If you don’t have chia seeds, you can skip them or substitute with ground flaxseeds. They will add a similar texture and provide a boost of nutrition.
How Long Can I Store Leftover Overnight Oats?
You can store leftover overnight oats in the fridge for up to 3 days. Just be sure to keep them in an airtight container, and give them a good stir before serving!
