Flourless, Sugar-Free, Gluten-Free Peanut Butter Cookies

Way back in 2007 I spotted a recipe for Flourless Peanut Butter Cookies on Cookie Madness, and you can imagine how the world *flourless* caught my eye in that recipe title. I’ve made quite a few Low-Sugar or Sugar-Free Cookies since those days, but these Flourless, Sugar-Free, Gluten-Free Peanut Butter Cookies that I adapted from Anna’s recipe are still my favorites. If you like peanut butter cookies, I promise you’ll love this healthier version.

I’ve made these cookies so many times through the years, and always enjoyed them. They’re a delicate cookie that can be a bit crumbly, so let them cool completely before you store the cookies. I use Lakanto Monkfruit Golden Sweetener (affiliate link) for slightly more brown sugar flavor in these cookies, but you can make this with any sweetener you prefer.)

My favorite sugar-free cookies are these Flourless, Sugar-Free, Gluten-Free Peanut Butter Cookies that I make over and over.


  • 1 large egg
  • 1 cup granular sweetener of your choice (see notes)
  • 1 tsp. baking powder
  • 1/2 tsp. Mexican vanilla (or vanilla extract)

  • 1 tsp. water
  • 1/3 cup chopped peanuts (optional)


  1. Preheat oven to 350F/180C.
  2. In mixing bowl, use electric beater to beat together the egg, Granulated Stevia or sweetener(s) of your choice, baking powder, and vanilla for about a minute.
  3. Add peanut butter and water and beat together. (The mixture was fairly dry; just be sure the peanut butter is mixed well with the other ingredients.)
  4. Add peanuts if using, and blend into dough.
  5. Use a large non-stick cookie sheet. Measure out a heaping teaspoon of batter for each cookie, roll into a ball, and then smash down with a fork.

  7. Let cookies cool well before handling.


I used Lakanto Monkfruit Golden Sweetener (affiliate link) for a bit more brown-sugar flavor in the cookies, but use any sweetener you prefer. Sweetener is calculated as zero net carbs for nutritional information.

I love Adams 100% Natural Peanut Butter (affiliate link) but any natural peanut butter will work.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Of course since there’s no flour or sugar these are a low-carb cookie, low-glycemic, Keto, and gluten-free cookie. They’re also much more South Beach Diet friendly than than a normal cookie, but if you’re following South Beach, nut flours are limited to phase 2 or 3. No matter what diet plan you’re following, you may want to use portion control if you’re actively trying to lose weight.

  1. Way to sweet1

    • Took me a minute to figure out that you meant “Way too sweet!” Sorry to hear you didn’t enjoy it. I have made these many times and there are quite a few good reviews and comments. I wish you had told me what sweetener you used and if you made any changes.

  2. Can homemade cashew butter be used in place of peanut butter? I want to try something different.


    • I haven’t ever tried it that way, so all I can really say is try it and see what you think. I can’t think of any reason why it wouldn’t work but I am not sure cashew butter will give as much flavor in a cookie as peanut butter does. But it might be great!

  4. Hi, i made a batch of these tonight as i had a rare sweetie craving, but they were too crumbly to eat as a cookie, just disintergrated into crumbs. any idea what i can do to firm them up a bit? The peanut butter i used (meridian) was peanut only with quite a high oil content. would that be the problem?

    • Sorry that happened for you. It is a fairly crumbly cookie, but they should stay together enough to eat them for sure! I’m guessing the high oil amount is the problem, since it’s only the peanut butter + the granulated Stevia that gives these structure. When I buy a jar of natural peanut butter, I sometime drain some off before using it, so you could try that. Hope that makes them work.

  5. Been craving the old fashioned pb cookie, but I am on Weight Watchers. Made these this afternoon and was very pleased with the outcome. I used the Stevia in the Raw like you did and I used a natural crunchy peanut butter. Just enough to kill those cravings.

  7. Hi! Do you have any suggestions for making these a high altitude friendly cookie? I was going to try them this weekend!

    • I live in Utah where the altitude is relatively high and haven’t had trouble with them. I’m afraid I’m not a good enough baker to know how to adjust for high altitude though, sorry!

      • I’m just north of you in Idaho (4700 feet, so borderline high altitude). I’ll just try them as is! Thanks for the quick response!

  8. Yummy! I used a trusted cookie sheet but mine burned on the bottom – even after I changed sheets and used the Airbake insulated sheet.  Could it be the agave syrup sunk to the bottom? I’m stumped.

  9. Made these tonight! They came out wonderful and tasted so good! Been craving a low carb no sugar cookie! Love your posts!!

  10. Made these tonight and they came out wonderful and tasted great! Thank you for posting this..Been craving a low carb cookie!
    Wish I could post a picture of them!

  11. Would these be lower in calories with PB2? I tried calculating it and it came out to 18 calories per cookie, but I'm not sure if I did that right?

    • I don't know enough about PB2 to know the answer to that; also I'm not sure it would work because the bulk of the peanut butter is important in this recipe. Love to hear what you think if you try it!
