If you love dessert bars but want to make them a little wholesome, swap out the standard flour and use oatmeal to make these chocolate chip oatmeal bars.

They are thick and chewy and make the perfect afternoon pick-me-up or post-dinner sweet tooth fix! I love making them for my family and know that it’s something more wholesome than a generic candy bar or ice cream.

Why this recipe works

  • 5 ingredients. Simple pantry staple ingredients mean no eggs, butter, or milk! Instead, I use mashed banana to add moisture and also extra sweetness.  
  • Quick and simple. With barely any prep time and just 15 minutes in the oven, these make a speedy, sweet treat.
  • Healthier. Similar to raisin cookie bars, these are packed with whole grains, healthy fats, and naturally sweetened; these make a fabulous guilt-free dessert.
  • Easy to customize. This is the kind of baked good you can easily adapt to use up any mix-ins you have on hand. I love to use up leftover nuts and seeds or even candy bites.
  • Perfect texture and flavor. These cookie bars are soft, slightly chewy, and have an almost buttery texture without any actual butter in it. It has notes of chocolate with every bite. They taste like a thick and jumbo oatmeal chocolate chip cookie but with a more tender exterior.

Ingredients needed

As mentioned earlier, this recipe calls for just five simple and wholesome ingredients. Here is what you’ll need:

  • Rolled Oats (Old Fashioned Oats)– They provide a chewy texture and a fabulous substitution for flour. They are also a much healthier alternative to it, providing fiber and protein too!
  • Almond Butter– Gives these cookie bars that buttery texture and flavor we love without any butter!
  • Maple Syrup– Provides sweetness and also masks any banana flavor. Do not omit, as it will change the texture of the cookie bars.
  • Bananas– Overripe, mashed bananas! The riper they are, the sweeter they will be! Bananas replace any need for butter or eggs while also providing sweetness and a softer texture.
  • Chocolate Chips– What is a good cookie without chocolate chips? I like using semi-sweet chocolate chips, but milk chocolate chips or dark chocolate chips work, as do chocolate chunks. 
  • Baking soda– Optional, but helps with the leavening of the bars.

How to make oatmeal chocolate chip bars

What I love about this recipe is that everything is made in one bowl! Clean up is almost non-existant.

Step 1- Make the batter. Stir together all the ingredients except for the chocolate chips. Fold them through, then transfer to a lined pan.

Step 2- Bake the bars. Bake the oatmeal cookie bars for 15-17 minutes or until golden on top.

Step 3- Cool and slice. Let the bars cool completely before slicing and serving.

Tips to make the best recipe

  • Don’t overmix the batter. When making the batter, mix everything until just combined. You don’t want these to turn out rubbery!
  • Avoid over-baking. These bars will continue to cook as they are cooling down. I like to remove them from the oven once the edges are golden brown.
  • Add mix-ins. Enhance the bars by adding mix-ins like pecans, walnuts, butterscotch chips, or vanilla extract. Like i said above, candy bits are also fab.
  • Press the batter firmly. Press it firmly into the baking pan when transferring the batter into the pan. This will cook them more evenly.
  • Cool completely before cutting. This is important to ensure the bars are fully set. 

Recipe variations

These cookie bars are very forgiving and have plenty of ingredient substitutions, including basic pantry staple ingredients.

  • Gluten-free oatmeal chocolate chip bars. Swap out the oats for gluten-free rolled oats or buckwheat flakes. 
  • Banana alternative. You can substitute the banana for unsweetened applesauce or pumpkin puree. Neither are as sweet as bananas, but they will still yield a similar texture. You may need to add extra maple syrup to make up for the lack of sweetness from the banana.
  • Use other nut butter. Swap out the almond butter for either peanut butter or cashew butter, or keep them nut free by using tahini or sunflower seed butter. 
  • Lower the sugar. Instead of maple syrup, you can use a sugar-free or reduced-sugar version.
  • Use regular sugar. If you don’t want to use syrup, brown sugar or coconut sugar work.  

Storage instructions 

To store: Store leftovers in the refrigerator in an airtight container. They will keep fresh for up to 5 days.

To freeze: Wrap individual bars in parchment paper and place them in ziplock bags or a freezer-safe container. They will freeze well for up to 6 months.

Reheating: These bars become firm once refrigerated, but to have a gooey cookie bar, microwave it for 20-30 seconds.

Frequently asked questions

Can I use instant oats instead of regular oats? 

Yes, instant oats will work for this recipe. However, the bars will be softer and less chewy.

Can I add an egg?

There is no need to add eggs to this recipe, but if you’d like to increase the protein, adding 1-2 eggs will not affect the texture.

    I have made this recipe SEVERAL times and it’s fantastic! Easy and I know all of the ingredients. I’ve used pumpkin puree from a can and applesauce since my husband can’t have bananas. I’ve also added more chocolate chips and tons of nuts because the base of this reciepe allows for variation and those of us with food sensitivities, this is PERFECT! Thank you so much for this recipe!

    We love this and have it every night for our dessert! We actually love it made with pumpkin puree instead of mashed bananas! Yum!

    Easy, simple and love the no added sugar. I substituted on cup of the oats for one cup of shredded coconut. Will make again.

    My sons and husband cannot have diary, gluten or eggs – so it is a trick to make anything special and this 6 ingredient recipe was THE BEST! It was PERFECT! I’m in Indiana and I have one son who’s living in Alaska for the next year. I wrapped and froze 4 oatmeal bars to send him. And I also couldn’t use almond butter (bc of one son), I made cashew butter and it turned out perfectly! EXCELLENT and SIMPLE recipe! Thank you!

  5. I have made these and they are yummy! I have been craving more chocolate and wondered if I could use some cocoa powder too. 🙂

      Hi, thanks for the recipe!
      In the video you use baking soda (1 teaspoon?) but that is not in the recipe. Is the original recipe meant to be with or without baking soda?
      And with 3 small- medium sized mashed bananas I had 1,5 cup. Isn’t 6-7 as written in the recipe quite a lot?
      Thanks, Imera.
