Bake a batch of these soft and chewy Banana Protein Baked Oatmeal Bars with all the sweet flavor of protein bar without fat or added sugar! The perfect high protein breakfast, snack or post workout meal.
Jump to RecipeThese bars are kinda like a cross between baked oats, protein bar and banana bread: Oatmeal that’s baked in the oven, but has protein powder and egg whites in it for a protein bump, and the mashed banana + cinnamon for the BB part.
Kill 3 birds with one stone I guess!
Another reason I really liked these is coz they’re freezer-friendly. This was actually the first time I actually froze some of my meal-prep snacks/breakfast add-ons.
I usually just eat them in like 2-3 days, but these went on for week!
What Protein Powder to use for Baked Proats?
I use a whey-caesin blend from Quest Nutrition. Their Vanilla, Chocolate and Peanut Butter are amaze!
All their flavors are stevia-sweetened, so they’re a lot lower in calories.
For a dairy free option, you might want to consider something else.
Ingredients for these Banana Protein Baked Oatmeal Bars?
- Rolled Oats – I wouldn’t recommend Instant or Quick since they’d get too soggy
- Mashed Banana – I’d recommend using completely ripe ones since they’re a lot sweeter!
- Protein powder
- Egg Whites – Added protein and acts as a bit of a binder in place of whole eggs. Also makes these low fat protein baked oats.
- Non-fat Greek Yogurt – Even more protein!
- Almond Milk – Any other will work well too, but this makes these baked oats dairy free.
- Cinnamon – Just complements the flavor well!
- Baking powder
How to make this Protein Oatmeal bake?
- Whisk the wets: mashed banana (mash with a fork first), milk, yogurt, egg whites
- Add the drys: oats, protein powder, baking powder, cinnamon
- Pour the mix into a parchment-lined baking dish
- Bake at 350°F for 22-25 minutes!
Dont’ forget to let the baked oatmeal cool before you slice, or it’ll be mush.
What makes this Baked Protein Oatmeal Healthy?
Dairy free – This recipe for baked oatmeal bars has no sugar, no egg, no oil, no butter, no milk – just non-dairy almond milk!
Sugar free – The bars are naturally sweetened by the banana, and if your protein powder is stevia sweetened, just makes it even more perfect!
No/Low Fat – The “oil and butter” in regular baked oatmeal is replaced with the mashed banana here.
Extra High Protein – There’s already protein powder in these oatmeal bars, but they also use egg whites instead of the egg for just pure protein and no cholesterol either!
For a Vegan baked oatmeal, make sure you use a compliant protein powder, and replace the egg whites with 2 flax eggs instead (2 Tbsp flaxseed meal + 6 Tbsp water let rest for at least 10 minutes).
Use Gluten Free oats if you have the restriction.
How to Meal Prep and store Oven-Baked Meal Prep PrOats
Store these homemade banana protein bars in the fridge for about 5 days, and enjoy them as a make-ahead high protein baked oatmeal for breakfast or an easy high protein snack.
You can also cut the bars into slices, wrap them in plastic wrap and stash them in the freezer in zipper bags. They should keep 2-3 months.
Another meal-prep hack is to cook the oats a greased and lined muffin tin to turn these high protein baked oatmeal bars into oatmeal cups instead. You want to bake them for just about 20 minutes in this case.

[…] Banana Protein Baked Oatmeal Bars […]
This recipe has been a staple in my home for a few months now…so easy & delicious!
Here are my tweaks:
1) I leave 1/3 of the oats whole, and pulse the rest into oat flour
2) Double the banana
3) I use a chocolate-based protein powder. Snickers or Twix is a hit!
4) Add chocolate chips on top before baking
5) Added some PB2 to the mixture a few times…oh boy, so good!
Thank you for this recipe!
omg I’m so happy this is a staple for you! Thanks for sharing those tips!
Absolutely love the chocolate protein powder idea to give it a candy vibe!
Just tried these out for the first time last night and so delicious! I added another banana and chocolate chips and also used Kodiak cakes protein oats in mine.
That sounds amazing! Have to try the extra protein version.
I used Orgain Protein Almondmild to give it more protein, and for my kids, I added in 1/2 cup of chocolate chips! It defeats the purpose of being low-carb/sugar, but the kids really enjoyed it!
I’m so happy those swaps worked out for you Bridget! This protein banana baked oats really is great for kids as well. And kid approved is always a good sign! 🙂
Fantastic as is & also very flexible to be tailored with variations stirred in (coco nibs, pecans, nutmeg) and/or on top (drizzled hazelnut cocoa butter). I doubled the recipe and used a 7 1/2 x 11 and it turned out perfect! This will be a regular on our weekend prepped breakfast rotation as a busy school administrator that is determined to stay healthy no matter how crazy things get! Thanks!
This really is so nice to hear Cindi!
I’m so so happy you loved these bars so much to make it a regular! Definitely a great meal prep lifesaver 🙂
YUM!! I loved this recipe!!!! So tasty!!!
I love your enthusiasm Lydia! I get a feeling you might have loved this baked protein oatmeal even more than I did, and that really brings a smile to my face 🙂
This was so delicious!! Made it 3x in a row, week by week I added new toppings. It’s so filling and delicious!
Oh my goodness Jasmine, I think you’re probably an even bigger fan of this recipe than I am! You make me want to experiment with toppings now too 🙂 I really am so happy you loved it so much.
These are so easy to make and tasted great! Love the macros too 🙂
I’m so glad you liked them Leah! The macros were probably my favorite part 😉
