Sugar-Free Flourless Chocolate Oatmeal Cluster Cookies

Sugar-Free Flourless Chocolate Oatmeal Cluster Cookies are easy and delicious, and these can be made with the sweetener of your choice! Even with some oatmeal these are fairly low in net carbs, and if you use gluten-free oats the cookies are gluten-free.

Years ago I spotted a cookie (no longer online) that reminded me of something my mother used to make, and I thought it would be fun to come up with a sugar-free version. After a few attempts I had two similar but slightly different versions of the cookies. I’m sharing an updated recipe here for the fudgy version of Sugar-Free Flourless Chocolate Oatmeal Cluster Cookies, and if you prefer a more cakey cookie (that’s a bit sweeter and also not completely sugar free) I’ll give you the printer-friendly link for that version below as well.

Photos here are the fudgy version of the cookies, but both versions look similar.

What ingredients do you need for this recipe?

Is this a low-carb cookie recipe?

These cookies do have oatmeal, so they’re not completely free from carbs, but they net carbs are pretty low, and  they’re tasty for a sugar-free treat. If you’re not watching your sugar intake, these cookies could be made with sugar and the cookies would be gluten-free if you used gluten-free oatmeal.

How to Make Sugar-Free Flourless Chocolate Oatmeal Cluster Cookies:

  1. First combine rolled oats, Golden Monkfruit Sweetener or sweetener of your choice, cocoa powder, and pinch of salt in a medium-sized bowl.
  2. Start with 1/2 cup sweetener, then taste to see if you want a bit more sweetener.
  3. In a separate bowl combine olive oil, vanilla, and egg.
  4. Combine wet and dry ingredients with a fork, stirring until all the cocoa powder has blended with the oil and egg, then chill cookies several hours.
  5. To bake, preheat the oven to 350F/180C.
  6. Line a baking sheet with parchment paper and make small balls of batter (about 2 teaspoons.)
  7. I smashed the cookies down with a fork a little before I baked them, which is probably necessary because they don’t spread out much.
  8. Bake 12 minutes, or until cookies are firm but not hard. They will harden a bit more when they cool.

I first made this with a blend of granulated Stevia and Monkfruit sweeteners, but now I'd use Golden Monkfruit Sweetener (affiliate link). Use the sweetener of your choice. Start with 1/2 cup sweetener and then taste to see if you want more sweetener; some people preferred a sweeter cookie.

If you prefer the more cakey and higher sugar version of these cookies,  you can see that recipe here.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Two things that caught my eye about these cookies were the use of olive oil, and the fact that the cookies didn’t have flour. Both those things make this a great cookie choice for the original South Beach Diet, but these cookies are phase two or three for South Beach, due to the oatmeal. (The cakey version that uses agave is probably phase three.) Cookies with oatmeal are not super low in carbs, but if you check the nutritional information you’ll see these are relative low in net carbs.

  1. oops I got all the dates wrong so glad there are recent ones.

  2. I don’t know if the comments are closed since the last one was 10 years ago but I recently found this recipe. I have made a few batches exactly as the recipe is presented and they were great. I’m not one of those folks who changes up a recipe in all kinds of ways from that presented but I was looking to reduce the ww points further, I substituted apple sauce for the oil. The substitution works nicely. For those looking to reduce fat even further, use applesauce. But kudos to Kalyn because while I may be able to tweak I can never create a recipe from scratch so finding this was a lifesaver for a little sweetness in my rather austere low glycemic diet. Thank you.

  3. Hi, I was just wondering if someone with type 2 diabetes can have this cookie recipe 

    • I am not qualified to give medical advice, so I can’t answer that question. But I’m in the process of calculating nutritional information for my recipes so I just calculated the carbs and these cookies have 6.8 carbs per cookie (due to the oatmeal). I am guessing that’s a bit high in carbs. Here is a round-up of lower-carb cookies, maybe one of those will work better for you.

  4. Needs a whole lot more sweetener. Very dry

    • Sorry you didn’t enjoy it. Did you follow the recipe exactly as written? What sweetener did you use?

  5. Well, I tried the first recipe, following it to the letter and the cookies are not sweet at all. They are very chocolaty, but not sweet. I think I will try sprinkling them with the granulated stevia to see if that helps, but I won’t make them again.

    • Sorry to hear you didn’t like them. Did you use the Stevia in the Raw Granulated Sweetener I linked to? I think everyone has their own taste when it comes to sweetness.

  6. Thank you! Thank you! Thank you! I have been off added sugar….as much as I can be living overseas…..for 6 weeks…..and have been looking for a cookie recipe that I can make that isn't dry, tasteless and that both my husband and I like. I have found it in this cookie! I did change things a bit……used butter instead of oil, used 1/3 cup stevia, 1 1/2 Tbs brown sugar, 5 shakes of cinnamon, about 1/4 cup chocolate chips. I will continue to play with the recipe but so far this is the best one! "Expat in China"

    • So glad you're enjoying it. And I'm glad you don't mind experimenting; I love it when people do that to adjust recipes to their own taste.

  7. Thanks for your speedy reply, Kalyn. I Binged my question and got varying answers. I think I'll try it with 1 whole egg and see what happens. If they don't work right, it's not the end of the world…I'll just go back to your original recipe. Merry Christmas!

  8. Yummy! I'm going to try the fudgy one since I don't have the agave nectar on hand. One question though. If I didn't want to use egg whites, should I replace that with 1 whole egg….or 2 whole eggs? Thanks for a great site. You really help me with my low-carb efforts!

    • Elizabeth, so glad the site is helpful for you. I haven't tested the fudgy version with whole eggs, so I'm not sure what to recommend. (I'm not a good baker, so don't know much about baking substitutions.) I would guess 2 egg whites = 1 egg, but whether it would act the same way in a recipe I have no idea.

  9. wow these look so delicious and easy
