I am always looking for a delicious, healthy way to start my morning off right. It was always a challenge for me to find a recipe that is healthy and appealing to my kids. This 30 minute Oatmeal Breakfast bar recipe is the perfect match for me and my kids. 

And because breakfast is the most important meal of the day, these healthy oatmeal breakfast bars are a great way to start your day and will leave your kids begging for more.

Oatmeal has been a great healthy way to start off your day for years. But as a kid, it may not always be the dish you first think of when your mom calls you down for breakfast. 



Luckily these easy Oatmeal Bars taste like cake, but will fill your belly long enough to get you to lunch. These Easy Breakfast Bars are full of healthy ingredients. Oats, bananas and peanut butter are a perfect mix for a heart healthy breakfast. Bananas are one of my favorite fruits and if you are like me then you always have a small stock of them in the kitchen.

With them being full of potassium, who wouldn’t want to always have them around. Oats are crazy healthy, being full of fiber, vitamins and minerals and when you combine everything together you’ve got yourself one tasty breakfast, brunch, snack or even dessert option!

Although these are considered breakfast bars in my house, they really can be eaten at any time of the day. They are perfect for bringing along for a snack or to be packed along with a healthy lunch. I love eating them with a yummy Strawberry Mango Smoothie or a scoop of some homemade Raspberry Ice Cream to make it more of a dessert. 



How to Make Peanut Butter Oatmeal Bars:

Making these Oatmeal bars are so easy to make and will leave you with your new favorite breakfast recipe in 30 minutes. There are several key ingredients to this easy breakfast bar recipe so here is what you will need:

  • Bananas: Make sure your bananas are ripe. The Riper they are the better your bars will taste.
  • Vegetable Oil: Some substitutions would be Olive Oil, Coconut oil or Canola Oil.
  • Brown Sugar: Everything tastes better with a little bit of sugar!
  • Eggs: Eggs give structure and will thicken your batter.
  • Vanilla: This will enhance the flavor of the recipe. Without it your bars will taste a little bland.
  • Salt: Salt makes everything taste better!
  • Baking Soda: This is the main ingredient that helps your batter rise when cooking.
  • All Purpose Flour: You can substitute this for Almonds flour to make these bars gluten free.
  • Rolled Oats: This is what makes your bars so healthy!
  • Milk Chocolate Chips: Everything’s better with chocolate! You can always leave the Chocolate Chips out to keep it extra healthy.
  • Creamy Peanut Butter: This will give them that distinctive taste leaving you wanting more.

If you love on the go breakfast and snacks try these breakfast bars too!



Tips to make sure your breakfast bars result in perfection:

  • Make sure you are using rolled oats for your recipe and not quick oats. This will help your bars hold up and not fall apart easily.
  • You can substitute a couple ingredients out for allergies, but make sure you don’t take out the bananas. The bananas are a big factor in the texture and taste.
  • Let your ingredients sit for a couple minutes to soak up all the moisture to make sure your bars don’t end up crumbly and hard to eat.



Can oatmeal chocolate breakfast bars be frozen?

Yes, absolutely! These Peanut Butter Oatmeal bars freeze great and keep their delicious taste even after freezing. Before you stick your bars in the freezer make sure you allow them to cool entirely. Place your breakfast bars in an airtight container when freezing them for later. 

To make it easier to eat them later I would suggest slicing your bars into the desired size and shape before sticking them in the freezer. When ready to eat just place one on the counter to thaw or nuke it in the microwave for a warm gooey bar!  



How long can you keep oatmeal breakfast bars?

If you are not freezing your oatmeal bars, generally they will stay good up to five days after you baked them. If there are any left to save for later, make sure you store your breakfast bars in the fridge in an airtight container to ensure they stay good. 



Can I add frozen fruit?

Yes, you can use frozen fruit or fruit in general to your oatmeal breakfast bars. Frozen fruit, will add more moisture to your bars.  Fresh fruit will add a little and freeze dried fruit may require an extra Tablespoon or two of liquid. 

If you want to use frozen fruit you don’t need to thaw them before you throw them in the mix. These breakfast bars are the perfect recipe to make your own and will taste amazing no matter what you add.

To make it more of a breakfast food, I omitted the chocolate chips and added dried organic cherries. With the peanut butter on top it tasted like a gourmet pb&j (lol) but was still delicious!
