Oatmeal Breakfast Bars

Breakfast  |  Published Mar 29, 2023  |  Updated Mar 28, 2023  |  By Tawnie

My soft baked, oatmeal breakfast bar is like your favorite bowl of oatmeal in bar form. I love having a variety of on-the-go breakfast options, but the chocolate and peanut butter layer on these bars puts this recipe at the top of my list. 

In an effort to make something with my overripe bananas that wasn’t banana bread, I made this recipe! It uses 2 bananas which is perfect because I always feel like I have just 1 or 2 lingering bananas on the counter waiting to be used.

These oatmeal breakfast bars come together easily and are so satisfying. Perfect for busy mornings or when you need a quick bite in the afternoon to hold you over until dinner.

Some of my other favorite quick snack options are these 5-ingredient energy bars, homemade protein bars, or these quinoa breakfast muffins are packed with protein too!

Reasons Why You Will Love My Oatmeal Breakfast Bars

  • Gluten free breakfast (be sure to look for gluten free oats)

Ingredient Notes

For the ingredient measurements and entire recipe, be sure to scroll down to the bottom of the blog post where the recipe card is located.

ingredients needed to make breakfast bars in small glass bowls.
  • Oatmeal: I tested this recipe using quick cook oatmeal and I love the texture of it. Using the old fashioned rolled oats will give the bars a chewier texture. You can pulse old fashioned oats a few times in a food processor or blender to break them down a bit if you don’t have any quick oats.
  • Bananas: 2 medium over ripe/spotty bananas are perfect for this recipe. About 1 cup mashed is what you’ll need.
  • Coconut sugar: either coconut sugar or organic cane sugar may be used here.
  • Honey: you can also use maple syrup, agave nectar or date nectar.
  • Creamy peanut butter: you’ll need some peanut butter for the bar and the chocolate topping layer, too!
  • Almond flour: almond meal also works well as an option. You can use them interchangeably in this this recipe.
  • Flaxseed: good source of fiber and omega-3’s.
  • Chocolate: I love using dark chocolate for this recipe. Feel free to use your favorite!

Expert Tips and Variations

  • Substitute almond butter or cashew butter for peanut butter.  Both of these options are similar to the taste and texture of peanut butter.
  • Add a scoop of your favorite protein powder in for a protein boost.
  • To make these bars a little less sweet, add in applesauce in place of the coconut sugar.
  • Add chocolate chips on top instead of the chocolate peanut butter topping.
  • Add just a layer of drippy peanut butter on top if you don’t want any chocolate in your breakfast bar.

FAQ

Can I freeze these oatmeal breakfast bars?

Yes! I like to wrap them individually and place them in an air-tight container. Freeze bars for up to 2-3 months.

How long do they last in the refrigerator?

Store in the fridge for up to 1 week.

Do I have to add the chocolate peanut butter topping?

Nope! You can leave it off, or just add a few chocolate chips or a drizzle of chocolate if you feel the thick layer is too much!

Can I use chia seeds rather than flaxseeds? ( don’t have flaxseed on hand) will already be subbing out the sugar for apple sauce.

Yummy is all I can say. I didn’t have any bananas so I substituted applesauce for them, I just really wanted to make them and didn’t want to wait. I also cut mine into 12 pieces, and each in half for easy nibbling. It is a very easy recipe and sets well.

You could very easily replace the egg with chia seeds! 1T Chia seeds + 2.5T of water is equal to 1 egg.

I did, only because I didn’t have any bananas handy. Still came out very well.

Thank you for the suggestion. I was thinking about trying pulsing the oats in a blender. I plan to make them tomorrow.
Once again thank you!
