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 and they are so delicious. Also, you won’t feel guilty for eating more than one. My husband and grandsons love them too! It’s a great snack for hungry kids.

  2. These look great but looking for a low sodium option to manage BP. What would omitting salt do to the recipe? Could I try 1/4 tsp or less?

  3. Love these! Have made “black forest” style with chocolate chips and cherries for more of a dessert bar, have also added coconut. Versatile, easy and so tasty! Try adding some honey too.

  4. The applesauce was at the bottom and I couldn’t even chew them because the oats were hard! What did I do wrong? I was so hopeful.
