Sugar-Free Flourless Chocolate Oatmeal Cluster Cookies are easy and delicious, and these are perfect to make with Golden Monkfruit Sweetener! Even with some oatmeal these are fairly low in net carbs, and if you use gluten-free oats the cookies are gluten-free.

Sugar-Free and Flourless Chocolate and Oatmeal Cluster Cookies finished cookies on plate

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.
