Flourless Peanut Butter Oatmeal Cookies

My favorite peanut butter cookie recipe is this flourless peanut butter cookie recipe I posted about last year.

Recently, I came across a variation adding oats to the batter on Domestic Fits. Same easy batter, but with healthy oats added to it. Genius!

I had all the ingredients on hand, so I was able to quickly whip this up this weekend, cram a few in my mouth between cleaning the kitchen, and pack a bunch for Mr. K to snack on at work.

  1. Hi! Loved the cookies but I’d like for them to be crispier. Do you happen to know if using granulated sugar would do the trick?

  2. I just made these and replaced the sugar for organic honey and used cinnamon instead of vanilla – it turned out so delicious. The texture very smooth (I only put it in the oven for 9 mins so it maintained a smooth non-crunchy texture which I prefer, but I also tried putting them in for longer to get some with a good crunch). Delicious! Thank you for the wonderful recipe! 

  3. Thank you! My husband loves this recipe. They are so good.

  4. I put dried Cranberries instead of the chocolate chips

  5. Did you flatten the balls before baking? Or will they flatten out from the balls?

  6. I would really love to make these. I’m type 1 diabetic and was wondering if you can help me with a substitute for the brown sugar. Anyone kindly suggest anything?

  7. oh, i see now. thank you!
