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.

Peanut Butter Oatmeal Bars with Chocolate Chips. Gluten Free!

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.

Behold, the ultimate cookie dough blob:

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

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.

Easiest Peanut Butter Oatmeal Bars with Chocolate Chips

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. A super generous quantity (shall I call it a blob?) of creamy PB provides all of the moisture these peanut butter oatmeal 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 peanut butter 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.

Flourless Peanut Butter Oatmeal Bars with Chocolate Chips

An easy, one-bowl recipe for peanut butter oatmeal bars with chocolate chips. Soft, chewy and gluten free!

Yield: 1 8x8-inch pan (16 bars)

Prep Time: 10 minutes

Cook Time: 22 minutes

Total Time: 32 minutes


  • 1 cup creamy peanut butter (crunchy will work too, though I prefer the texture of the creamy)

  • 3/4 cup light brown sugar

  • 1/2 teaspoon baking soda

  • 1/8 teaspoon kosher salt

  • 1 large egg, at room temperature

  • 1 teaspoon vanilla extract

  • 1/2 cup semi-sweet chocolate chips

  • 1/3 cup old fashioned rolled oats


  1. Place rack in the center of your oven and preheat oven to 350°F. Line an 8x8-inch baking dish with parchment paper and lightly coat with cooking spray. Set aside.

  2. In a large mixing bowl, beat together the peanut butter, brown sugar, baking soda, and salt on medium speed until well combined.

  3. Add the egg and vanilla, then mix on medium low, just until incorporated. By hand, stir in the chocolate chips and oats.

  4. Press the dough into the prepared baking pan. Bake for 22 minutes, until golden and the top is set. Let cool completely in the pan. Remove, slice and serve.

Bars will keep in an airtight container at room temperature for up to 1 week, though they will become a bit firmer. Separate layers with parchment or wax paper.
