We’re SO obsessed with this recipe that we just had to share it with you! These Banana Peanut Butter Overnight Oats  are the perfect M1 or M2. They pack lots of protein, thanks to the peanut butter, chia seeds, and of course, Tone It Up Protein, so you’ll be building lean muscle and feeling satisfied all morning.

  1. My new favorite M1, 😋

  2. this is my absolute favourite recipe from the TIU Nutrition Plan! I almost didn’t even try it because I don’t like soggy oats but when I read the recipe I had to make it RIGHT NOW! I substituted 1/2 the amount of oats for homemade protein granola added right before eating so I get a tasty crunch ;P

  3. I am having the hardest time committing to the nutrition plan because my kids have food allergies – including soy and nuts- and almost every recipe calls for something I can’t risk contaminating my kitchen with, and I can’t figure out a way to substitute without compromising the #tiuapproved – ness! Any other food allergy TIU girls with tips?

    1. Hi Melody,

      We are an allergy family too! 3 of us (including me) are allergic to tree-nuts & peanuts, I am also allergic to dairy, oats, bananas,tomatoes peaches and plums and have celiac disease. One of my sons also has a bean and sesame allergy in addition to peanuts. Needless to say, it is NOT a fun household to live in foodwise! I just made this recipe with Eden Foods Brown Rice flakes, So Delicious coconut milk, Wow butter (soynut butter) but you could use Sunbutter (sunflower seed butter) , Sunwarrior classic blend vanilla protein powder (all fermented brown rice protein powder) and plan to top it tomorrow morning with strawberries! Would I love to follow the meal plan as is? Absolutely! Is i frustrating? Yes!! But some things can be modified pretty easily. I find the sources of protein to be most difficult since I am a vegetarian that does not do well with beans. My son with the sesame allergy used to be severely allergic to soy (birth to 9 years old). Now at 11, he does not test allergic anymore but does have an intolerance. We used to use Coconut aminos in place of tamari sauce for stirfrys etc. In place of nuts, we use pumpkin seeds and sunflower seeds from Gerbs Allergen Friendly Foods. You can buy them on Amazon or directly through their website. All of their products are handled in an allergen free facility. I hope this help Melody! Stay Strong!!

      1. I LOVE this comment. I never thought I’d find another person with a longer allergy list than me. I use Sunbutter in all of my ONO recipes with rice milk, and I highly recommend it. Can’t wait to also try Sunwarrior! THANK YOU!

  4. These were so good! banana and peanut butter is one of my favorite combos and I loved how it was just ready to go in the morning! My husband loved them too! I am also looking forward to the coconut berry ones next week! #TIUteam #lookforLOVE #TIUhubby

  5. This was admittedly my very first ONO recipe, and I loved it!! The only change I will make for next time is dividing this up into 3 portions instead of 2. I don’t eat like a bird or anything, but it doesn’t usually take much to fill me up when it comes to oatmeal. So I’ll call it a win, thanks Ladies!!

    1. I’d love to know the answer to this! I’ve used unsweetened rice milk, which totally works, but wondering if they recommend something better. Also allergic to peanuts, but Sunflower Seed Butter is an amazing replacement!

  6. After a year and a half of being a TIU girl I have yet to try overnight oats!!! Just rediscovered this recipe after reading one of the recent posts. Just curious if this is meant to be eaten cold out of the refrigerator or warm it up? I guess maybe it depends on preference but I was wondering what you girls liked best!

  7. What are the nutritional values of this…I halfed the recipe except for the protein powder and my lifesum app says it’s almost 400 calories! And I haven’t even added the banana yet. It’s also soo small like barely half my mason jar. What type of gluten free oats are yall using? I used the Bob’s Red Mill gluten free old fashioned rolled oats. I also used regular PB but the calories are pretty much the same.

  8. Just had this for the first time and OMG!! Seriously moorish!…Goes down a treat…so tempted to eat the other half of the mix but I won’t. Great thing is that I can make it wherever I am as long as I have 2 containers & a fridge. Need to check out the other ONO recipes. Thanks K& K…I’m hooked!

  9. I made these for Mon & Wed M1’s this week and premade a PB&J pancake for Tuesday’s M1 :)
    These PB & Banana ON oats tasted good in the bowl together—yes, I had to take a taste! Excited to try these tomorrow!
