Breakfast doesn’t get much easier than overnight oats. Especially when you combine chocolate and peanut to give you the creaminess of chocolate peanut butter overnight oats! 🍫🥜
Although I am usually a savory breakfast type kind of girl, I get in the mood for something sweet, and overnight oats always hit the spot. I mean what is better than making your breakfast before you go to bed and then waking up with it ready?!

I make a lot of overnight oats in our house. They make a super easy breakfast for me and a snack for Michael. He is always on a mission to add more calories to his diet and I can pack overnight oats with a lot of healthy fats, protein, and complex carbs for a healthy snack. It’s so easy to change the flavors to keep it interesting too.
Just like all of my overnight oatmeal recipes, these are well-balanced for balancing your blood sugar and energy levels. It is packed with protein from the protein powder. It also has complex carbs and fiber from oats and chia seeds, which helps slow down digestion. And healthy fats to keep you fueled until your next meal.
Enjoy them as a quick and easy breakfast, or as a post-workout meal!

What are overnight oats?
Overnight oats are similar to your typical stovetop oatmeal but without any cooking. Rolled oats are mixed with a liquid (usually milk) and other flavors, spices, and ingredients and then let to sit overnight. As they sit, the oats absorb the liquid and become a thick and chewy texture, just like cooked oatmeal. Depending on how much milk you add, you are left with almost a pudding-like consistency.
They are quick and easy and so delicious! What I love about overnight oats is the flavor possibilities are endless. Some of my favorite add-ins are nut butter, fruit (fresh or dried), spices, yogurt, cocoa powder, and protein powder.
Chocolate peanut butter overnight oats ingredients
- rolled oats – opt for certified gluten-free if needed
- chia seeds – this help absorb the liquid and adds some more fiber
- protein powder – optional, but helps to add more protein to the recipe. I used peanut butter protein to amp up the peanut butter flavor even more
- cocoa powder
- cinnamon
- salt – to help bring out the flavors
- peanut butter
- milk of choice – use non-dairy milk to keep them vegan
- optional toppings – sliced banana, peanut butter, cacao nibs…

How to make chocolate peanut butter overnight oats
- Make overnight oats. Add all ingredients to a medium jar. Stir well to combine until all ingredients are thoroughly combined. Place the lid on the jar and put the oatmeal mixture in the refrigerator for at least 2 hours, or overnight, until the mixture thickens.
- Enjoy! Eat out of the jar or transfer to a bowl and top with toppings of choice.




How long does it take for overnight oats to work?
Overnight oats don’t really need to be “overnight”. I actually usually do “quick overnight oats” and make them the morning of, let them sit for an hour or two, and then enjoy. Two hours is usually enough for the chia seeds and the oats to absorb the liquid.
I also don’t use that much liquid as I love them super creamy. The reason why most people make them at night is that it just makes your morning easier. Just grab it and enjoy! But if you forget, you can totally make them on the same day.
How long do overnight oats last?
Overnight oats can last for up to 5 days in the fridge. The longer they sit, the more time to soak up the liquid. Overnight oats will last 5 days but will be a bit mushier than on day 3 or 4.
They make a great option for meal prep – I will make a few servings at a time (these jars are perfect for them) and just keep them in the fridge for something quick and easy to grab during the week.

Substitutions and additions
Overnight oats are so customizable and you can tweak them to your preference and your macronutrient needs. Here are a few suggestions for this overnight oat recipe:
- oats – you can use quick-cooking oats instead of rolled oats, although the texture will change slightly. While you can use steel-cut oats for overnight oats, they are a lot coarser (they aren’t as processed) and need to soak for at least 10-12 hours. Will will need more liquid if using steel-cut oats as well.
- peanut butter – any kind of nut butter will work or even seed butter if you are allergic to nuts. Try almond, cashew, pecan, sunbutter (sunflower seed butter), or tahini.
- protein powder – you can swap with your favorite protein powder, but it might change the flavor some. Also, since protein powders have different absorbencies, you might need to adjust the liquid.
- cocoa powder – cacao powder can be used instead.
- milk – any kind of milk will work. Feel free to use nut milk, oat milk, coconut milk, or regular dairy milk.
And here are some additions:
- sweetener – add a little maple syrup or honey if you want them sweeter.
- vanilla extract – to add a touch of vanilla flavor.
- powdered peanut butter – if you want to lower the fat some but still want that peanut butter taste, you can use powdered peanut butter instead. I haven’t tried this, but it should work the same.
- greek yogurt – add a 1/2 cup of yogurt to make them extra creamy. You may need to adjust the liquid if doing so.
- toppings – sliced banana, strawberries, peanut butter, cinnamon, and chocolate chips are all great choices to put on top!

the best. Have been eating them every morning for the past 2 months and have not gotten sick of them. Sometimes I add in shredded coconut. So good!
Kelly says
So glad you like them, Brennan! Thanks for trying them!
Jenn Trimmier says
I didn’t have PB protein powder so I left that optional ingredient out. We thought these were a little runny for our taste the way we did them but will try again once we have the right flavored protein powder.
Kelly says
The protein powder helps absorb the liquid so it will change the consistency if you leave it out. You can swap in your favorite protein powder though and it should work the same. Hope that helps!
