Flourless Peanut Butter Oatmeal Bars with Chocolate Chips want you to embrace The Blob Phase.

Easy Peanut Butter Oatmeal Bars with Chocolate Chips. Gluten Free!

Are you acquainted with The Blob Phase? It’s the moment right after you’ve realized that you wasted no fewer than five hours watching back-to-back Friends reruns and eating Cheez-Its, but before you’ve mustered the energy to scoot the empty box off of your abdomen.

When The Blob Phase hits, the only thing that’s less appealing than spending one additional second covered in cracker crumbs is the thought of getting up to do anything else. Thank goodness for Instagram. Blob Phase, recommence.

About the Best Chocolate Peanut Butter Oatmeal Bars

These ooey gooey peanut butter oatmeal bars were designed for The Blob Phase. In fact, they beg you to embrace it. An ultimate lazy dessert—only one bowl and limited measuring is required—these soft and chewy bars are at their best when at their blobbiest.

I suggest you make two: one to bake into peanut butter oatmeal bars and the other to devour immediately. I don’t consider myself a big cookie dough eater (I usually prefer the final baked version), but I couldn’t keep away from the mixing bowl. I am still stunned that a flourless, butter-free cookie dough can taste this incredible.

Flourless Peanut Butter Oatmeal Bars with Chocolate Chips. Easy and gluten free

Yes, you read that properly—butter free. In addition to being flourless, these miraculous bars contain no butter and still taste amazing, a feat made possible by our good friend, peanut butter. My Flourless Peanut Butter Cookies use the same no-butter strategy. A super generous quantity (shall I call it a blob?) of creamy PB provides all of the moisture these bars need to be perfectly soft and chewy, without the addition of butter. Old fashioned oats add a little texture, and a handful of chocolate chips keeps things sweet and right.

Full disclosure: we are on our third batch of oatmeal bars in 10 days. When a dessert is this easy, this tasty, and (compared to other blondie bar recipes) this much better for us, it’s a little hard to control the urge not to bake just one more pan.

  1. Unfortunately, my batch turned out burned, dry, and crumbly. I use an oven thermometer all the time, so I know that the temperature of the oven was not the problem, nor was the metal pan I used. Major bummer, especially considering the wasted ingredients.2 stars

    1. Hi Mary, I’m sorry to hear you didn’t enjoy the recipe. It’s hard to know what may have happened without being in the kitchen with you, but I know it’s disappointing to try a new recipe and not have it come out, so I truly wish you would have enjoyed these!

  2. Thank you so much to share your recipe, i love peanut butter oatmeal bars,

    i have make this for follow your recipe.4 stars

  3. I made these two days ago, and they are super yummy. I used Kirklan natural peanut butter from Costco and an 8×8 glass Pyrex dish for baking. I baked them for 22 mins. I did not line the pan, just used a little cooking spray. They taste like chocolate chip peanut butter cookies. Thank you for the recipe!5 stars

  4. My son is on the fodmap diet and this seemed like a good recipe that works with that diet. He doesn’t like chocolate chips so I used flaked coconut instead. Very addictive!4 stars

  5. Excellent recipe! Really easy to make and the bars come out perfect every time. I know that for a fact; I made 300+ of them (20+ batches) for our town’s annual holiday cookie tour. They were a huge hit. People couldn’t believe there was no flour or butter/shortening in the recipe. They freeze really well, too, which was a big plus when making 25 dozen for an event!5 stars

  6. These bars are delicious. Ive made them a few times and they are always great.
    I do wish i had the caloric information though as i track my calories every day5 stars

    1. So glad you enjoyed them Rosanne! Nutritional information is something I started adding to recipes in January 2016. Unfortunately, it’s a time-consuming process, so I’m unable to go back to all my past recipes to add it. The good news is that you can calculate the calories for free at MyFitnessPal (there are other similar sites too). I hope that can be a helpful resource for you!
