You’ve never had oatmeal like this before! This thick and creamy banana cream pie overnight oatmeal smoothie combines that stick-to-your-ribs feeling of a bowl of oats with the silky smooth texture of a smoothie. Vegan, gluten-free, and packed with plant-based protein and fiber, it makes a perfect healthy and easy breakfast or snack!

Hi, hello, and happy Saturday!
Are you excited? I’m excited. Mostly because today’s recipe features one of my very favourite ingredients of.all.times – OATS. It’s no secret that I love those little guys to bits, not only for how healthy and delicious they are, but for how versatile too!
I mean, this isn’t exactly your typical bowl of oatmeal…

We’re going back to the basics today, because sometimes simple is best.
As much as I love experimenting with fancy flavour combinations, there’s no denying the simple appeal of the classics. I mean… they’re classics for a reason, right? And I’m sure we can all agree that the combination of bananas and oats is definitely a classic.
BUT! Today’s banana cream pie overnight oatmeal smoothie (mouthful alert!) is a classic with a twist, because while it’s made with the tried and true combination of bananas and oats, there are a few little details that make it stand out in a crowd.

First, the overnight bit. Yes, that means you need to do a little prep work in advance, but it’s like 2 minutes of hands-on time and then all the magic happens while you sleep.
And, yes – this step is COMPLETELY necessary. I tried to skip out on it to see if I could get some instant gratification, and it was a COMPLETELY different smoothie. You know how they say that good things come to those who wait? They were talking about this smoothie.
Not only does a little bit of chill time let the oats absorb the almond milk and get all fluffy and creamy, but it gives the bananas time to freeze – and that’s what takes this baby from a simple banana smoothie to a banana cream pie smoothie.
I mean… just look at that creaminess!

So swoonworthy.
I was originally going to call this recipe a banana bread smoothie, but banana cream pie is what came to mind as soon as I had my first taste because of how sweet, banana-y, cool, and creamy it was.
I normally use 1/2 cup of oats in my overnight oatmeal smoothies, but I decreased it to 1/4 cup for this recipe and added more banana instead. The result is a smoothie that’s slightly less doughy, but just as thick, comforting and satisfying… especially with the right kinds of toppings…

Banana Cream Pie Overnight Oatmeal Smoothie
- Total Time: 3 hours 5 mins
- Yield: 1 serving 1x
Ingredients
- 1 1/2 – 2 medium ripe bananas, frozen (150 g)
- 3/4 cup (177 ml) unsweetened almond milk
- 1/4 cup (20 g) rolled oats**
- 1/2 Tbsp (8g) natural almond butter***
- ½ tsp vanilla extract
- 1/8 tsp ground cinnamon
- pinch of salt (optional but highly recommended)
Instructions
- The night before, peel your bananas and cut them into small chunks. Transfer the chunks to a plastic bag or container and place them in the freezer. Then, add all the remaining ingredients to the bowl of your blender and give them a stir to ensure that everything is well combined. Cover and place in the fridge for at least 3 hours, preferably overnight.
- The next morning, remove your blender bowl from the fridge and add the frozen banana chunks. Blend on high until a smooth and creamy consistency is reached, adding more milk if the smoothie is too thick. Transfer to a bowl or glass, add desired toppings, and enjoy!
Notes
* Cook time refers to chilling time. ** Be sure to use certified gluten-free oats if you need this to be gluten-free. *** I like to use almond butter because it has a sweet and mild taste. Feel free to use your favourite nut/seed butter, but the flavour might shine through a little. **** If your smoothie is too thick for your tastes, add a few extra splashes of milk to the blender.
- Prep Time: 5 mins
- Cook Time: 3 hours

Amazing! More delicious than ice cream!
Only different method I used was letting my bananas sit for a little before making this. An older banana is a lot sweeter!
I made this using 1 1/2 frozen bananas. The smoothie was wonderfully creamy, and the bananas provided just the right amount of sweetness. I enjoyed the mild banana flavor, but I might consider using a full 2 bananas next time to make the banana flavor even more prominent.
Made it, loved it, can’t wait to make it again! I’ve been really enjoying adding a few tbs of oats to my smoothies lately- it makes them extra luscious and keeps me satisfied longer. I used raw walnuts instead of almond butter in this one + added a ton more cinnamon and I swear it tasted like a banana-y cinnamon roll. Nom!
I’m so glad you made it and loved it, Robin! Thanks for taking the time to leave a review and let me know 😀
As soon as I get my hands on our blender again, this is happening. There are truly no smoothies that look as luscious and delicious as yours, Amanda. An overnight oatmeal smoothie may be the strangest breakfast concept I’ve introduced to my family, but once you go there, there’s no turning back.
Right?!?! I’m completely spoiled because no smoothie that I make without oats tastes any good to me anymore 🙁
I blended this smoothie this morning and added a scoop of protein powder to it; so delicious and filling! I just might make this my new go-to breakfast smoothie, assuming I remember to prep it the night before 🙂
That looks really good. Thanks for sharing!
This looks so amazing. I want it right now.
I tried this smoothie this morning, and it was really good! 🙂 I put shredded coconut on top too. 🙂
That sounds awesome, Natasha! I’m glad you liked it 😀
When the weather gets warm, I’m definitely making this.
UGH…so creamy! Only you would think to make overnight oats into a smoothie. Genius!
p.s. I love that spoon. 🙂
Haha! I literally look at things and think to myself: “I wonder if I can blend that” 😆
I have been seeing your smoothies ALL over Pinterest lately… And every single photo is so gorgeous!! I’ve probably pinned them a hundred times by now. ? This one looks just as delicious, but would you believe I’ve never had banana cream pie?? Crazy!
Aww! Thanks so much for your kind words, Amy! You should the to make a healthier version — you’re freaking BOMB at doing that!
You’re the sweetest Amanda — thank you!! ❤️❤️
I always add raisins to my oatmeal bowls when I’m making them on the fly. PB and raisins. If I follow a recipe (or an idea like almond joy or pumpkin etc) I will omit the raisins and use what the recipe says. I love this new link-up! Thanks for creating it 🙂
I think raisins are probably my favourite dried fruit… which is funny considering I used to hate them as a child. Thanks for linking up this week, Ellie!
Hey! The most oats I can tolerate at at time is 1/4 cup–I know, it sucks–so I haven’t been able to try any of your overnight oatmeal smoothies yet. Definitely giving this one a try!
I’m glad to hear that this one will work for you, Joyce! I hope you like it 😀
Mmm banana cream pie. That brings back fond childhood memories. This ones perfect for me as I tend to like less oats in my smoothie… and won’t say no to extra banana. What is so special are your tips for the preparation. How else would I know to use frozen bananas and soak the oats the night before!? Simple brilliance = big difference.
I always say that it’s the little things that make the biggest differences 😉
What brand(s) of almond butter do you like? Thanks.
I mostly use Justin’s, Maisie Jane’s, or Barney Butter. It’s not that easy to find almond butters that don’t “contain traces of peanuts,” so I just grab whatever I can eat, really.
I’m pretty much 90% smoothie at this point because it’s all I ever have. I don’t even know why I have teeth anymore. I need to try this!
Chewing is overrated 😉 But I know what you mean! I love smoothies because they satisfy both the hunger and the thirst… which has been kind of insane in the dry winter air.
I have been making and drinking smoothies for a while now. This one sounds yummy and I will defiantly try the recipe. In fact, it was you that gave me the tip on letting my smoothie mixture sit overnight which in hindsight makes perfect sense.
I freeze my smoothies. I have the habit of gulping down anything cold giving me a tummy ache, freezing slows me down and no ache.
Take care:)
I’ve never tried freezing my smoothies — now you’ve got me curious!
Banana cream pie is amazing and this smoothie looks incredible! Now I kind of want both!
I like the way you think 😉
This looks dreamy! My staple oatmeal ingredients (other than bananas, of course) are cinnamon, vanilla extract, and nut butter! I’m pretty convinced that those are capable of taking any sweet recipe from good to great. 🙂
Truth! Nut butter is actually the thing that keeps me from wasting a lot of my ‘failed’ recipe experiments. Everything becomes edible when it’s drowning in nut butter 😀
Oh wow – this smoothie has the creaminess factor mastered! So swoonworthy indeed!
I adore oats too and my fav add in recently has been a sprinkling of cardamom powder with a smidge of cinnamon – the two together is oohlala swoonworthy! 🙂
Hope your weekend is wonderful Amanda!
I seriously don’t use cardamom enough! Thanks for reminding me that I need to dig it out of my spice cupboard and put it to good use, Shashi!
This looks so, so, so good. We give my son a smoothie every morning and sometimes on Saturdays (aka the mornings Daddy isn’t home ;)) I get lazy and just give him multiple smoothies for breakfast, rather than one as a snack. I think I would feel a little better about my ‘dirty’ secret if I knew there was a little extra oomph in it to keep him full!
Lucky little guy! You definitely wouldn’t find me complaining about smoothies for breakfast 😀
So I adore that the pinch of salt is in there. 🙂 Happy dance over here in Cleveland.
I inadvertently made some kind of crazy smoothie yesterday which tasted exactly like Cake Batter to me. It just needed a little vanilla, cinnamon and a touch of salt. 🙂 It was borne of desperation because I was out of all fruit with the exception of bananas and frozen pineapple. I also tossed in some carrots, almond milk and oats (thanks to you). Strange, but good for the win.
Now this on the other hand sounds wonderful and wonderful for the win.
Carrots = cake batter?!! You’re a magician! I’m in the middle of a serious fruit crisis here. I canNOT keep ripe bananas in my home… I used up my last one yesterday and now I’ve got nothing but greenies 😥
I love this time of year for baking banana bread and smoothies. It’s the only way I can get myself to eat those suckers!
I think I like smoothies more in the winter than I do in the summer — I’m just crazy thirsty around this time of year (thanks dry air!) so smoothies always hit the spot.
I will never make my oatmeal without cinnamon 😉
Me neither! I bury my oats in it 😀
You make so many interesting and unique smoothies. I’ve never made any smoothies that I’m especially proud of but this does motivate me.
Confession: I was once tempted to throw in cooked rice to see what would happen. I just like to experiment 😆
