Jump to Recipe

Banana Oatmeal Breakfast Bars fresh from the oven and cut into bars.Since we’re back from our best ever Hawaii vacation and Whole30 is over, I’m craving all things BUT eggs for breakfast. Actually… we’ve kept up the hard-boiled egg habit, but I usually eat them as snacks instead of for breakfast. 

No, I’m talking oats, peanut butter, honey, carbs ETC. Whole30 did us so much good, but I was very ready to pick up the recipe testing on these bars I had first tried back in November. So many of my favorite things, all wrapped up in bar form, and totally okay with me to eat for breakfast or snacks. Not to mention such a great use of leftover bananas! 

Ingredients in these Banana Oatmeal Breakfast Bars:

  • Bananas – Duh!! The good news is they are not required to be super ripe for this recipe to succeed. I used up our ripe ones and had to continue testing with newer bananas. Still worked just fine. 
  • Rolled Oats – Old-fashioned, rolled oats. I use Bob’s Red Mill. Use the gluten-free specific kind if you need that!
  • Peanut Butter – We love PB. Hope you do too. If you don’t, another nut butter would probably work but I haven’t tested anything but peanut butter.
  • Honey – Used as the sweetener in the recipe, and I just love the PB/honey combo.
  • Almond Milk – But you can use any nut milk or dairy milk if you want.
  • Baking Powder – For some puff!
  • Cinnamon – Cinnamon and peanut butter is just a combo I love. For yummy flavor!
  • Salt – A bit of sea salt to balance all the sweetness.

Can I use a different sweetener instead of honey?

I have personally tested this recipe with maple syrup instead of honey, and I prefer honey as the sweetener. There’s just something so good about the honey/peanut butter/banana combo that I love. Maple syrup adds a different kind of sweetness that I usually love, but not in the case of these Banana Oatmeal Breakfast Bars.

That being said, you are always welcome to make this recipe your own and try it any way you want!

Can I use a different nut butter instead of peanut butter?

I have not tested this recipe with anything other than peanut butter, but I do think it would be delicious with any nut butter, particularly cashew butter. I was specifically going for the PB/banana combo when I was testing out this recipe.

Are these Banana Oatmeal Breakfast Bars good for meal prep?

Yes! We love them for a breakfast or snack prep. Each bar comes in at around 225 calories. Have one for breakfast with a hard-boiled egg for a macro balanced morning meal, or grab one as a snack to help keep you satisfied between meals.

I keep these bars in a airtight container in the fridge or freezer.

How long do these Banana Oatmeal Breakfast Bars last in the fridge?

Keep these bars in the fridge in an airtight container for up to 4 days.

Are these Banana Oatmeal Breakfast Bars freezer friendly?

Yes! During testing, I froze several of these breakfast bars and was able to thaw and eat them later without being able to tell they were frozen.

I tried two different methods of thawing which both worked very well:

  • Overnight thaw – Pulled a frozen breakfast bar out of the freezer and put it in a container in the fridge. Ate the next day.
  • Counter quick thaw – Pulled a frozen breakfast bar out of the freezer and left it on the counter for one hour. Was still very cold when I ate it but was thawed and soft.

How long do these Banana Oatmeal Breakfast Bars last in the freezer?

Keep these bars in the freezer in an airtight container for up to 3 months.

      Hi Bethelda – Yes, I use natural peanut butter with just peanuts and salt in the ingredients list. Any creamy PB would work 🙂

    Are these supposed to come out soft? Mine turned out soft and crumbly. Not hard like a granola bar. I was expecting them to be harder.

      Hi Pam, yes they’re supposed to be soft and chewy! Not like a granola bar, more like a soft oatmeal cookie texture. Hope you liked them!

      These would be great with some warm peanut butter drizzled on top, or depending on your diet, a hard boiled egg or fresh fruit. Great for breakfast or snack!

    So yummy! Think you could use apples in this? If so how would you change the recipe?

      Hi Missy! Thank you! I’m not exactly sure how to make this recipe with apples without some testing, but here’s one I came across that looks similar: https://iowagirleats.com/2017/10/13/apple-cinnamon-oatmeal-bars/
