It is so hot these days. Is it just me? What are the heat levels like by you? We’re averaging 95 degrees F daily with a heat index of “feels like 105 degrees F”, so Gav and I are doing our best to manage how many times we turn our oven on. You better believe that our air fryer is getting used far more, our Instant Pot too, our stovetop recipes are all being meal prepped at once, and our mug cakes are winning. Also? Our ice cream game is totally up right now. Anything to add as little heat as possible, while keeping cool.

This is why I knew it was time to whip up a new overnight oats recipe. I’ve done some in the past, alongside some chia pudding recipes, and I fell in love. I’ve enjoyed oatmeal for breakfast for years, although I enjoyed it warm. I wasn’t sure about eating them cold, but after one bite, I KNEW that overnight oats were for me. If you want a nourishing, filling, easy and meal prep-able recipe that will also keep you cool? Read on, friends. 

Ingredients for overnight oats.

What are overnight oats?

Overnight Oats are as simple as they sound: you mix all the ingredients for your oatmeal, place it in a jar, and let the fridge do the rest of the work for you overnight. The oats soak up the liquid, the flavours meld together, and breakfast (basically) makes itself! 

I’ve been in love with banana bread recently, so I knew I wanted to make a Banana Bread Overnight Oats. I used some of my favourite banana bread flavours and mixed them here. Let’s get into the simple ingredients that make these overnight oats so delicious.

Easy ingredients

  • Oats – You knew this would be the star ingredient here, right? I love using Bob’s Red Mill Gluten Free Old Fashioned Rolled Oats as my oats of choice for this and all my oats recipes. They’re certified gluten-free, are high quality and are Non-GMO. I use them in everything from my homemade oat milk, to my oatmeal chocolate chip cookies, and the list continues. Old Fashioned Rolled Oats are the oats to use for overnight oats because they slowly soak up the liquid and maintain their structure.
  • Chia Seeds – I love also adding chia seeds into my overnight oats. It creates an even creamier texture (YUM!).
  • Bananas – I mean, we are making banana bread overnight oats, right? I love using heavily spotted or black bananas, and the riper the better. They help to naturally sweeten the dish and hey! You’re having a fruit to start your day too!
  • Cinnamon – Cinnamon adds such a yummy flavour and is so reminiscent of banana bread for me that it’s a must. Feel free to even experiment with more cinnamon here or a different kind.
  • Sugar – this is totally optional if you want it sugar-free, but it really ups the flavour with just a small amount. 
  • Nuts – I used walnuts, but you can use seeds, extra oats, pecans or any add-ins you usually add for your banana bread.
  • Sea Salt – a pinch of sea salt really enhances all the flavours here, so don’t skip it!

Expert Tips & FAQ

  • When using such few ingredients, be sure to use high-quality ingredients since they will all shine through. That’s one of the reasons I love using Bob’s Red Mill Gluten Free Old Fashioned Rolled Oats. I know I’m going to taste every ingredient here and I want them to be the best. That also goes for your vegan milk. If you’re using fresh vegan milk and want to meal prep it, use it like the day you make the fresh milk, not on the last day.
  • You can totally meal prep these. You can make like three at a time, or even 5, and just eat one each morning. An easy, readily available breakfast option!
  • I don’t necessarily recommend frozen bananas here since they may get a little slimy, so I would stick to fresh bananas.
  • Be sure to really mash your bananas! They will *slightly* discolour, so if you have a picky child or don’t want it to discolour, mash it right before eating and swirl it in. 
  • Feel free to customise! Use more oats, less oats, more milk, less milk, add in some coconut yogurt, it’s all up to you!

    New breakfast go-to. Loved the addition of the chia seeds – not something I typically put in my overnight oats. Used maple syrup for sweetener but don’t think I’ll use any next time. It was plenty sweet with the banana. Definitely recommend adding the nuts for a great crunchy topping.

    I just made this for the first time – I used unsweetened oatmeal milk. Can’t wait to have it for tomorrow’s breakfast! So easy and quick. And I love how all the flavors tasted together. Yup. I snuck a taste! I’ll definitely be topping it with my homemade soy yogurt and chopped pecans. Thanks for what I know is gonna be delicious. I’ll share it in stories on my IG profile (@glutenfreediva)

    LOVE this recipe! I love all things banana (especially banana bread!) but can also get really lazy about baking, so I HAD to try this. I almost always have bananas and oats on hand, so this took all of 2 minutes to prepare before getting into bed. I’m also lazy about making breakfast in the morning, so the fact that I could just pull this out of the fridge in the morning was PERFECT. I also threw some pecans, PB2 powder and mini vegan chocolate chips on top and I will 100% be making this again in the future. HIGHLY recommend! 🙂

    This recipe is amazing! Highly recommend. It’s easy and the perfect recipe for a weekday (or weekend). I used brown sugar and added blueberries on top.

    Delicious! I added a half scoop of vanilla protein powder to bump up the protein and omitted the sugar since the powder is sweetened, and sprinkled some chopped walnuts as suggested before eating. Loved how easy and flavourful this was!

    Absolutely delish! I must confess that I took a small taste before pouring into my jars (yes I doubled the recipe- I have become so confident in the recipes you post – not a single one has failed me or wasted my ingredients) and let’s just say one jar didn’t get to sit overnight. The flavour is just wow! Truly banana bread in a jar. Excited to try it tomorrow when it gets a chance to sit. Plan to have it as a healthful dessert.

    This overnight oat recipe is absolutely perfect for summer! No one wants to eat warm oatmeal on a hot day, so this is a great alternative. Banana bread lovers rejoice because the combination of vegan chocolate chips, crushed walnuts and banana truly emulate banana bread, without all the added calories! It’s so delicious that I’m excited to eat my oats every day of the week!

    • Gavin | Jessica in the Kitchen says:

      Wow, what a great review thank you so much Ocean! We’re so happy that you like it so much.

  10. Carly says:

    Made this a couple days ago (omitted the extra sweetener since bananas have enough sugar for me and I don’t like my oatmeal too sweet) and had it for breakfast today. It’s AMAZING! Perfect breakfast after a hot and humid morning run (or just any day if you need to grab breakfast and go)!
