Peanut Butter Banana Overnight Oats

If you’re following me on Instagram, then you already know of my overnight oats habit. See, I have class on Tuesdays and Thursdays from 8 am to 5 pm, which is borderline blasphemy. The last thing I want to do on those early mornings is set my alarm clock even further back to cook up breakfast.

Enter the beauty of overnight oats. I throw these together the night before and then bring them to school to eat during my first or second class. That way, I can wake up a little later and I’m not left feeling hungry at like 10 am after eating breakfast at the crack of dawn.

The recipe I’m sharing today is a peanut butter banana variation, but I’ve really run the gamut of flavors– mixed berry, pumpkin (shocker), chocolate peanut butter banana, etc. Lately I’ve been thinking of doing a fall-inspired concoction with some dried cranberries and cinnamon. The possibilities are endless! I feel so alive!!!

Peanut Butter Banana Overnight Oats
Calories: 310 | Fat: 6.0 g (Sat Fat: 0.8 g) | Carbohydrate: 52.6 g | Fiber: 13.2 g| Protein: 27.1 g

1/2 C uncooked oats (my current favorite is Mother’s rolled oats, but plain Quaker Quick Oats will do ya dandy)
1/2 C unsweetened vanilla almond milk (also just a matter of preference and calorie consciousness)
2 T protein powder (I use Whole Foods 365 Whey Protein Powder because it’s cheap and moderate in calories)
1 T PB2
1/2 to 1 packet Splenda
1/2 of a small banana
1/4 C Fiber One

1. The night before you want to eat the oats, combine all of the ingredients (except for the Fiber One) in a container with a lid. Stir well because encountering clumps of protein powder will make you never want to eat again.
2. Cover and store in the fridge overnight.
3. In the morning, top your oats with Fiber One and dig in!

When I first started overnighting it with my oats, I never used protein powder. The taste still rocked but I did notice a huge difference in my how long I stayed full once I added it.

That being said, this breakfast is perfect before a late morning workout. The whole grain carbohydrate of the oats and simple carbohydrate of the fruit will energize you, and the protein will tide you over until lunch.

If you want to change up your flavors, take out  the PB2 and banana. Mix it up however you’d like.

Feeling inspired? I’d love to hear your flavor ideas!

  1. Do you heat the oats up in the morning or do you eat them cold? Because I’m all for the idea, but cold oats sound…less than appealing.

    Just wondering! Love the blog, by the way!

    • Hi Kate! I either eat them cold or at room temp. Eating them cold isn’t as weird/gross as it sounds because they don’t have the same texture as normal stovetop or microwave oats. If you want them more room temp, nuke them in the microwave for ~15 seconds. Keeping them in your backpack through your 8 am physiology class also serves the same purpose.

      Thanks for reading!

    • Hi Becky! Most of the time, I just omit the PB2 and add different types of fruit instead. I like blueberry, banana, and strawberry. You could also try adding nuts. Or if you want a chocolaty version, add a tablespoon or so of cocoa powder or chocolate PB2!

  2. Just curious, how did you figure out the calories? I’m adding everything together from this recipe and it’s at like 400 calories. Maybe I calculated it wrong?

    • Becky, maybe you used different brands of almond milk or protein powder, but the rough breakdown is: 1/2 C uncooked oatmeal (150), 1/2 C unsweetened almond milk (20), 1 T PB2 (25), 2 T protein powder (40), 1/2 banana (45), 1/4 C Fiber One (30) = 310 calories. Not sure how you ended up with 400!

      • Thanks! I think I just didn’t convert the serving size right on the protein powder. So on the 365 protein powder is 2T considered half a scoop? Thanks for all of the help!

    • Hi Irene! PB2 is a powdered peanut butter that has had most of the fat removed. You re-hydrate it with water and use it like normal peanut butter! Here’s a link if you want to read more about it: I’ve gotten it at both regular and specialty grocery stores, and I’ve also ordered it online from Amazon. I highly recommend it!

  3. hey I just found your blog and I love it! I was wondering if you cook the oats before you mix everything together and refrigerate or if you just eat the uncooked oats? thanks!

  4. I’ve just found your blog, and I love all of your meal ideas – especially these overnight oats. They’re so handy! I’ll definitely be making them this week, which will be busy with exams so I’ll need something to fill me up. x
