We are always on the hunt for a quick grab-and-go breakfast. This one hits the nail right on the head. 

It is super simple to make, under 30 minutes, and the flavor is spot on. All you have to do is mix your ingredients, bake, and frost. Can’t get much easier!

Oh, and they are kid approved! My son loves to grab one of these as a mid afternoon snack or treat. Toss them in your freezer to extend the life and have them around for a quick snack attack fix. 

Oatmeal Breakfast Bars

IMG_6432

Ingredients for easy oatmeal bars:

  • Rolled Oats– Rolled oats are what gives this recipe it’s classic oatmeal flavor. 
  • All Purpose Flour– Also referred to as white flour.
  • Baking Soda– A leavening agent that helps give lift to your baked good. 
  • Baking Powder– Also a leavening agent.
  • Salt– Salt is added to recipes as a flavor enhancer. 
  • Cinnamon– Cinnamon is key to giving this that classic flavor. 
  • Brown Sugar– Adds a slight rich molasses flavor to your bars.
  • Vanilla Extract– Use pure vanilla extract and not imitation.
  • Milk– We make this with regular 2% milk, however we have also used coconut and almond milk with success. 
  • Eggs– Large eggs at room temperature work best. 
  • Vanilla frosting– I recommend using this recipe, but any vanilla frosting will do. 

Difference between quick oats and rolled oats:

Rolled oats tend to be thicker than quick cut oats. This makes them perfect for creating granola bars. I have used both in this recipe. We prefer keeping it to rolled oats. This gives you a sturdy bar that tastes incredible. 

Optional mix-in ideas for oatmeal:

We like this recipe as written, but you could also add in some of your favorite oatmeal mix-in’s. Some of our favorite ideas are listed below for you to consider. 

  • Toasted Diced Nuts
  • Coconut
  • Dried Fruit
  • Flax Seed

    Just made this tonight and it’s cooling now. Can’t wait to have it tomorrow morning. Question do you store this in the fridge?

      Hi Gwen, I would store this in either a ziptop bag or in an airtight container inside the refrigerator. It should keep for up to five days.

      I haven’t posted my favorite version yet, but here is a quick breakdown: 1/2 cup butter, 1-/2 cups powdered sugar, 1-2 tablespoon heavy cream, 1/2 teaspoon vanilla

      Whisk the butter and powdered sugar until combined. Add cream and vanilla and whip 5 minutes, or until light and fluffy.

    The kids have just gone back to school, and they’ve been saying they get hungry during the day, so I’ve been looking for a good bar recipe I could send with them. This worked out fantastic! There are some changes I made to fit their dietary needs (like using almond milk and quick oats instead), and this recipe is a great base for alterations with fruits and add-ins, so I can see this being a favorite for a good while. Thanks for the delicious recipe!

      This makes me so happy to hear! It’s a go-to for back to school for us. My teenager loves to keep these on hand for breakfast or packed lunch.

        October 21, 2022

        Hi Nina, Sorry about that! I used to include oat flour, but have since removed it and found that these bars are perfect without. Just forgot to remove that from the instructions. Fixed. 🙂
