You know what I love? When my friends text me for food ideas. Sometimes it’s “what should I make for dinner?” And sometimes it’s a little more specific like, “Do you have any healthy oatmeal breakfast bars (nut free!) that I can send with my daughter to school with?”

I always come through on the first question, but to the latter question, I can now say YES. I do now. And I can also say that I never knew I needed this apple oat bars recipe as much as I do!

In our current morning routine, we rush out the doors on preschool days. It’s a struggle to get there by 8, and breakfast is at 8:30 so we NEED to be there by 8:15. You feel me, right? There’s just no time for a sit-down “first breakfast.” (We can’t be the only family!)

And then there are the other days. The morning we walked to Target first thing in the morning? No time for fruit soaked oatmeal. The morning we walked to the farmer’s market first thing in the morning? No time for breakfast tacos. (Ok, this morning there probably is time, but I’m usually desperate to get my cup of coffee and Demi is desperate to get her beloved porridge from 3 Bear Oats.)

So what happens on all of these times that we don’t have time for a real breakfast? These healthy apple cinnamon oatmeal bars. 

We’ve been eating these apple oat breakfast squares a lot on these rushed mornings and the girls LOVE them. I love that I can make a big batch and store them in the freezer (easy!) and that they are starting their day with a nutritious “first breakfast” that’s got whole grains, fiber, and a little protein. (healthy!)

Healthy Baked Oatmeal Bars Recipe Nutrition + Swaps:

This oatmeal breakfast bars recipe is pretty healthy all on its own, but you can make a few swaps if you would like to make them even healthier, or if your kids are young (between 1-3).

Originally, these apple oatmeal bars were made without flour and brown sugar, but as my kids got older and I got a little more flexible, I added a little flour and sugar too help the texture of these oatmeal breakfast bars stick together.

If you would prefer to leave them out, simply omit the flour and add an extra 1/4 cup of honey (1/2 cup total).

    Yum, I love oatmeal in any form and especially when it is easy to transport! I will be making these this week and I know Sloane will love them too!

  2. Arianne Gravunder

    we just made these. I wasn’t sure what to do with the butter. Mine turned out a little bit more cake like than your pictures. Not sure what I did wrong, but they were still good.

    • Emily

      Hi Arianne, thanks so much for writing, I just added the butter into the instructions. Sorry about that! You just dot it on the top, so it really just adds flavor, doesn’t do much else. Glad you liked them!

  3. John Baxter

    I just made these. They came out a little more cake like. I am putting them back in the oven a little longer as the
    top is brown but underneath is still wet. I did substitute almond milk. I think it might be better with a half cup of milk instead of a cup. Just thinking out loud. They are good, though.

    • Emily

      Hi John! How did it turn out with a little extra time in the oven? They definitely are more cake-like than granola bar, so hopefully they turned out just right!

  4. Sharon Annett

    In an effort to make these plant based, I made these with a couple of substitutions – almond milk, and peanut butter instead of eggs. The honey is questionable – but, decided to change that next time. They turned really good. Will definitely be making these again.

  5. Anne Kim

    Hi, Emily~
    I’m glad to find you ^^
    I’m korean and also live in Korea.
    So.. I’m just confused what kind of measuring cup you used. Cause 1 cup means usually 200millimeter in Korea. Thanks ~~ and take care amid outbreak of Covid 19.

  6. Nadine Michelle

    They were decent. I didn’t love the texture, it was a little tough but maybe I just don’t like oats like that. They don’t taste like store bought which is good and bad. I guess I thought they’d taste different but always worth trying new recipes.

  7. Deborah

    This recipe makes a delicious, nutritious oat apple breakfast bar. Keep them in the freezer, and a 30 second microwave zap yields a quick and tasty breakfast! Will definitely bake these again! A winner.

  8. Tut Gramling

    This is a family favorite! Dan and I really like eating these bars as much as our grandgirls! They have just a hint of sweetness, and satisfying, as well as high on the yum factor.

  9. Amy M.

    Hi Emily! I love your content. I’m making these bars tomorrow as the next day is my first day back to full-time work and I need a quick breakfast. Do you think quick oats would work? Maybe just be a little more mushy? I have a huge Costco container of quick oats, so I might give it a try and see what happens. Thanks!
