How to make oatmeal breakfast bars

  1. Measure all the dry ingredients in medium bowl.
  2. Whisk the dry ingredients together using a fork.
  3. In another larger bowl, measure all the wet ingredients.
  4. Then whisk the wet ingredients together.
  5. Now combine the dry ingredients with the wet ingredients and give it a good stir.
  6. Let the mixture set for 20 minutes so the oats absorb the moisture and the flavors of the oatmeal bars really blend.

Then fold in the walnuts and cranberries and transfer it to a baking dish lined with parchment paper. You want to bake it until it’s golden brown in color and firm when pressed against.

If you use a square 9×9 baking dish like I did, you can easily cut the breakfast oatmeal bars into 16 squares.

 Tips for making breakfast oatmeal bars

  1. Let ingredients sit to absorb moisture. This is key to making the oatmeal bars recipe successfully and ensuring that it holds together without crumbling. The mixture needs to soak before baking, or it will be not stick together.
  2. Use a larger piece of parchment paper than necessary. This will allow some of the paper to hang on the sides, making it easier to lift the bars out of the pan and slice them neatly. Plus easier clean-up!
  3. Double the recipe for a bigger crowd. The recipe doubles just fine. But if you double the recipe, use a larger baking dish and add 10 minutes to the baking time, or bake in two separate dishes.
  4. Switch out the add-ins. The recipe is so versatile to make it based on your taste preferences and available ingredients. I love the combination of cranberries and walnuts with oatmeal bars, but you can use other nuts, chocolates or seeds.

  1. I’ve made these many times. Always a hit! Ive even given them in cute parcels as a gift
    I’ve also substituted the amount of apple sauce for half butter half yogurt or just butter instead of the applesauce since I didn’t have apple sauce and it turned out really good. I also added extra coconut and came out great!!

  2. Hi, I don’t have cane sugar. Not a fan of sweeteners. Can I use plain white sugar or brown sugar? I also have molasses…? any suggestions are appreciated. Thanks!

    1. Yes, either the plain white sugar or brown sugar should work. You can also make it sugar-free by omitting the cane sugar or using mashed or pureed fruit in the base recipe.

    1. I have yet to try that, but I think it could be a fun idea! It might be a little dry though because the applesauce helps add moisture.

  3. Made these using pecans, and subbing maple syrup for half the sugar amount, since I was short on walnuts & sugar. I’ve eaten 2 every morning with coffee and yogurt- they’re great slathered with almond butter or butter!

    1. This recipe calls for ¼ cup applesauce! No need to cook the rolled oats before using in this recipe. Hope this helps!

  4. These are so great! I added pumpkin purée, pumpkin spice, and chocolate chips to mine for a yummy fall snack. Are these okay to be wrapped up and stored at room temperature? Thanks !
