I tend to be one of those people that has a tiny sweet tooth in the mornings. I want something just a little sweet, but you’ll almost never see me reaching for a donut in the A.M. It’s just a bit too rich for my blood that early (hit me up later though)!

That’s why I love the balanced richness of these Chocolate Chip Banana Overnight Oats. A little bit fruity, a little bit chocolatey—they are my favorite way to get a nourishing and satisfying breakfast fast! Welcome to the magic that is that is overnight oats!

What are overnight oats?

You make overnight oats by mixing rolled oats with liquid and other mix-ins, and let it rest in the fridge for at least two hours, or preferably overnight (hence the name!). In the morning, you can grab it straight out of the fridge and eat it like a pudding—no cooking required. Or you can heat it up if you prefer.

What makes overnight oatmeal so great?

Overnight oatmeal has been part of my weekly food prep routine for almost a decade now. Here is why it’s such a staple in our house:

  • You can make them your own. Make them vegan, gluten-free, or in whatever flavor combo strikes your fancy! It’s all doable because overnight oats are completely customizable. We’re covering Chocolate Chip Banana Overnight Oats in this post (which is a great, simple recipe to start with), but once you get the idea of overnight oats down, you can go wild making your own creations!
  • They can be as nourishing as you want them to be. You are in complete control of how healthy or decadent (or both!) these oats become. Reduce the added sweeteners, mix in some protein powder or collagen peptides, add in some superfoods like hemp seeds or chia seeds. The possibilities are endless!
  • They taste decadent and delicious! The oats soften up in the fridge to make a thick and sweet pudding that is totally yummy with a creamy texture.
  • Overnight oats are the perfect prep-ahead breakfast. Spend just a few minutes in the evening, and you’ll have a grab-and-go breakfast in the morning!
  • Overnight oats are easy to make in bulk. They are a staple of many meal prep menus for good reason—you can mix up an entire week’s worth of breakfast in just a few minutes.

  1. First, I have to mention that I tried overnight oats a few times and hated them. I tried this recipe and LOVE it. I did not include chia seeds, I also didn’t add the banana. It was delicious. I wanted to add the banana this morning after heating up the overnight oats but it was so good without it and will be even better next time I try this and use the banana.

  2. I made this recipe, but customized it a bit: used the full banana, 1 tbsp mini chocolate chips, 1 tbsp honey, oat milk, and added a tbsp of peanut butter powder. I’m obsessed. Such a great recipe and love how hard it is to mess up.

  3. I made these and once again I am so happy with the way they turned out! I love all of the recipes I’ve tried from Wholefully!!! Thanks you so much!!!

    1. YAY! Thanks, Jeanne! That’s so great to hear. Thanks so much for taking the time to come back and tell us about it. We really appreciate it =)

    1. Hi, Dominique! Overnight oats are very forgiving with substitutions and easy to customize. You could use regular yogurt in place of the Greek or even plant-based yogurt. If you’d prefer to leave out the yogurt altogether, you can add more of your milk of choice in it’s place. It won’t be quite as thick and creamy, but it will still be delicious! Hope this helps!

  4. Hi Cassie! I signed up, but never got my e book, nor emails. I have checked and confirmed over and over again.

  5. Hello! I’m a little confused on the calorie count. I put in all the ingredients and it’s sitting at 479 calories! I chose 2 tablespoons of semi-sweet chocolate chips and only 1 tablespoon of honey. I can’t seem to make it ever 388 calories. Did you use sugar free chocolate chips?

    1. The numbers are automatically calculated, so I’m not sure exactly what the calculator used. Different brands can vary in calorie count, so I’d guess that is where the discrepancy is coming from.
