This Oatmeal Breakfast Bars recipe is basically like oatmeal in bar form for on-the-go breakfast and snacking. They are more substantial and healthier than a packaged breakfast bar, and can be easily customized with different add-ins based on preferences. Made with staple pantry items, these are easy-to-make and can be stored for a few days or frozen for months!

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. These are absolutely delicious! On my second batch in 2 weeks and added fresh blackberries this second time. Love the variations you can make with this recipe. Thanks so mucho!

  2. Hi! Thanks for a simple and direct recipe. How many bars is a serving (based on the nutritional facts)?

  3. Hi and thank you for this delicious recipe! I seriously LOVE oatmeal and am always looking for different ways to eat it. I made this recipe as stated except left out the white sugar and used applesauce instead of oil. It’s good this way, but I can see that it would be better with dried cranberries and walnuts, so I will do that next time. I’m going to freeze some of these for later. My better half always has a large slice of banana bread for his “snack before breakfast” but I want something healthier so here it is! Bonus: healthier and also delicious!

  4. Another weekly devotee here, I love how filling these are as a grab and go breakfast. I dont always have apple sauce on hand, so i mash up an apple a little, that works. The chunks are not even noticeable. Also I use regular milk since that’s what I have, also works fine, this recipe is hard to mess up.

    1. I made these bars but decided to give them my own twist. I’m not big fan of cinnamon, cranberries, using sugar or apple sauce so instead I doubled the vanilla extract, added dark chocolate, honey, macadamia nuts, almonds, raisins and hazelnuts. Taste pretty good although not that sweet, next time I’ll use more honey. Defo recommend as a healthy alternative

  5. If substituting honey for the sugar, how much would I use? Also, would I need to adjust the amount of almond milk? These look absolutely yummy and right up my alley.

    Thank you.

  6. I have never had a recipe tell me to soak my ingredients before baking but it really makes the biggest difference such a good tip. I love these bars! I make them for my husband and his colleagues each week and as a snack for myself when I’m working, I was so tired of spending €2 + on a pack of 6 sugary breakfast bars now I can make my own for much cheaper and exactly how I like it. Thank you!

  7. Hi, I’m having a hard time producing the right result. The bars come out very spongy and chewy. So the first time I used quick oats and figured that’s what went wrong. So the second time I used old fashioned oats but the texture was still the same. I am baking around the time suggested. The other changes I made to the recipe is that I’m using 1/4 of honey in the bars in place of the sugar. I’m also using frozen berries. Do you have any advice? I really want a healthy homemade breakfast bar but one that is a different texture..more crumbly..or cakey..versus spongey and gummy

    1. It’s likely chewy because of the honey as a wet ingredient instead of the sugar as a dry ingredient. The addition of the frozen berries is also likely to add moisture to the bars. I’d recommend sticking to add ins like nuts, chocolates, dried fruits, or seeds. I’d also recommend either omitting the cane sugar or using mashed or pureed fruit in the base recipe.
