My mum is a type 2 diabetic and she’s sometimes bored of keto brownies, or almond flour recipes. She’s after truly fudgy brownies, with real crackle on top, gooey you can’t get that without all-purpose flour

Obviously, all-purpose flour is higher in carbs than keto-friendly flour, but if used in small amounts in combination with sugar-free monk fruit sweetener, you can bake a diabetic brownie recipe with four times less carbs than regular brownies.

What Are Sugar-Free Brownies?

Sugar-free brownies are the healthier version of classic brownies. While the traditional brownie recipes are made with refined sugar and sugar-loaded chocolate, this sugar-free brownie recipe is a sugar-free, low-sugar alternative.

It’s a great sugar-free dessert made with ingredients void of any added sugar, and they are therefore very low in carbs.

This said, I am an expert at healthy brownie recipes, and this recipe is too high in carbs for you I have so many options for you like my coconut flour brownies, Greek Yogurt brownies, or date brownies.

Ingredients For Fudgy Sugar-Free Brownies For Diabetics

It’s a very easy recipe, the batter is ready in 10 minutes, and all you need to make these sugar-free brownies are a few simple ingredients.

  • All-Purpose Flour – You will be surprised that you can actually bake fudgy diabetic brownie recipes using all-purpose flour. You don’t have to use almond flour or coconut flour. It’s all about balance and keeping the carbs low and I have shown my expertise in using flour and delivering diabetes-friendly pancakes with my sugar-free pancakes!
  • Unsweetened Cocoa Powder – The key ingredient for gooey chocolate brownies is cocoa powder.
  • Baking Powder for just a little rise.
  • Sugar-Free Crystal Sweetener – I like to use a combination of white erythritol Mon fruit blend with some brown erythritol that crackles the top of the brownie. I used erythritol but allulose or tagatose would also work. Check out my review of keto-friendly sweeteners to learn how to pick the best.
  • Sugar-Free Chocolate Chips – Feel free to use milk or dark chocolate chips, I do prefer dark chocolate to enhance the chocolate brownie flavor. If you don’t have sugar-free chocolate chips, you can make my chocolate chip recipe.
  • Large Eggs – Bring the eggs to room temperature 30 minutes before. Eggs are naturally low in carbohydrates and the binder of these healthy brownies.
  • Melted Unsalted Butter – Cooled for 5 minutes but still a bit lukewarm so it melts the sugar-free sweetener.
  • Salt to enhance the chocolate flavor
  • Vanilla Extract for flavor

How To Make Sugar Free Brownies

Preheat the oven to 350°F (180°C). Line an 8-inch x 8-inch brownie pan with parchment paper. Oil with cooking spray. Set aside.

Preparing Sugar Free Brownies

  1. In a large bowl, whisk the melted lukewarm butter and sweetener.
  2. Whisk in eggs and vanilla extract until well incorporated.
Making Diabetic Brownies
  1. Fold in the unsweetened cocoa powder, flour, baking powder, and sugar-free chocolate chips. Stir to combine nicely, into a thick, smooth brownie batter.
  2. Transfer the batter to the prepared baking pan and bake them at 350°F (180°C) for 20 to 25 minutes or until the top is dry, crackles and a toothpick inserted in the center of the diabetic brownies comes out with a bit of crumbs. Let the brownies cool down in the pan for 10 minutes, then take them out and let them cool on a cooling rack before slicing.

Baker Tips To Make Diabetic Brownies

  • Store in the fridge for extra fudgy texture – the texture will get extremely rich, and fudgy when cold. Place the brownies in an airtight container in the fridge to increase their fudgy chocolate texture.
  • Avoid cold eggs – the contact of lukewarm butter and cold eggs will clump the butter.
  • Use a combination of white and brown sugar-free crystal sweetener – brown erythritol contains more moisture, it makes the brownies crackle on top and even fudgier.
  • Don’t be afraid of flour – regular flour is higher in carbs but it’s the key ingredient to deliver a real brownie texture. In this recipe, only a small amount is used which keeps each slice of brownies to 8 grams of net carbs and no sugar added!

Frequently Asked Questions

Can I Replace The Eggs With Chia Eggs?

Yes, flax eggs or egg replacer might work to make a vegan sugar-free brownie recipe.

What Can Replace Sugar In Brownies?

To make a low-sugar brownie recipe, you can replace the sugar with a crystal sweetener like erythritol, allulose, or tagatose.
Don’t use artificial sweeteners like sucralose, acesulphame K, or Aspartame. Sugar in brownies doesn’t only add sweetness but also texture and artificial sweeteners can’t bring that.

Are Sugar-Free Brownies OK For Diabetics?

Yes, these sugar-free brownies are very low-GI desserts and are suitable for diabetics.

    61 Thoughts On Sugar-Free Brownies
    1 2
  1. Hi!looks like a great recipe.
    I would like to make them dairy free.
    Is there an oil that you recommend that I could use to substitute for the butter?

  2. These look wonderful for a newly diagnosed Type 2 Diabetic. But, I am confused as your preliminary information says equipment includes a 9-inch square pan, but the directions say to cover a(an?) 8-inch brownie square pan. A bit confusing, I think. Please advise. Thanks. Looking forward to making them soon.

  3. This recipe sounds great and I would love to try. Can I substitute the coconut oil with vegetable oil or butter? Can the coconut flour be substituted with more of the almond flour? I’m just wanting to make them with what I have in my pantry. Would like to make them for my Mom today! Thanks!

    • For the batter, you can use butter and for the chocolate drizzle, you can use vegetable oil.
      Coconut flour can’t be replaced in this recipe as it’s more absorbent than other flours. If you use just almond flour, it might struggle to come together.
      It might work by adding a touch of ground flaxseeds, but I can’t guarantee that.

  4. 5 stars
    I followed this recipe exactly, and it is literally my favorite brownie recipe that I’ve ever made, and the recipe is so simple.

  5. These look so delicious, but unfortunately I don’t have almond flour and have oat flour. Will it still be okay if I use oat flour as a substitute?

    • Oat flour will work, same amount but it’s not a keto friendly flour. A better swap will be sesame flour or sunflower seed flour, both are keto approved. Enjoy, XOXO Carine

  6. 5 stars
    This is very good! Whoever I only baked it for 15 min and it was close to being too dry so I think I’ll check it at 13-14min. Next time. Also it is more like cake but still delicious. I have a few ideas to make it more brownie like if they down work I’ll try you other brownie recipes. 💗. I drizzled Lily’s white and dark chocolate on top. Yum! I’m actually excited it turned out more like cake because I’ve tried to make keto cakes with countless fails but I think this will work perfectly for cupcakes and cakes. Thank you!

  7. My partner is diabetic and I am interested in finding some healthy recipes for him and myself. I am not diabetic but I could lose a few pounds.
    So I am really trying to keep both of us eating healthy.

    Haven’t tasted yet. Question- do you drizzle after one hour in the fridge or before placing in the fridge for one hour?

    • You can do both, if you drizzle before, the chocolate wil set and gets crunchy in the fridge. If you do it after, it will stay liquid. It depends on taste, I like it cold and crunchy 🙂 Enjoy he treat, XOXO Carine

    So since starting keto over a year ago I’ve been looking for a brownie recipe….and I’ve found it! I’ve used this recipe more than once and its my favorite dessert! It comes out perfect each time…fudgy and delicious! If you haven’t tried this recipe yet you’re missing out! THANK YOU for coming up with such a delicious brownie! ????

    • This is such a beautiful comment to read! Thanks so much for joining my keto blog. Enjoy the sweet treat around here. XOXO Carine.

  10. Hi, how can I replace de 1/2 cup of sweetener? I only have liquid or Zucra ( sucralose ) in envelopes… Thanks

    • I am not familiar with sucralose at all so unfortunately I can’t recommend on something I did not try. Enjoy the blog recipes. XOXO Carine.

    Hi Carine,
    My sister has type 1 diabetes and does not like coconut, can I just use more of the almond flour or do you have any recommendations as to what flour I could replace it with.
    Thanks Carine.

    • I did not try the recipe without coconut flour so I dont know how much more almond flour you will need. Usually you need way more almond flour to replace coconut flour, could be up to 4 times more. Otherwise you can try my almond flour avocado brownies, 100% type 1 diabetes-friendly. Enjoy the recipes on the blog. Have a Merry Christmas, XOXO Carine.

    • I did not try to freeze those as they keep well for few days in the panry in a cookie jar. I think they should freeze as well as regular brownie. I would defrost the day before on a cookie rack at room temperature. Enjoy. XOXO Carine.

    • Do you means eggs that you beat with a beater before adding into the brownie batter? if so, yes it won’t change the recipe. You can beat the eggs and add them beaten as soon as you don’t change the amount of eggs used. Enjoy the brownie, XOXO Carine.

      • Egg beaters are a product that does not contain cholesterol as it does not have egg yolks included in it. It is sold in the dairy section of a store. People use it in place of regular eggs in recipes when they are watching their cholesterol intake.

    • Hi! It won’t be appropriate in this recipe because it is using lots of coconut flour – a very absorbent flour that won’t work with chia eggs. Chia eggs don’t add enough liquid as eggs do to make this recipe work. If you love vegan brownies, I will recommend my vegan brownie sweetened with dates (no other sweetener added, 100% naturally sweetened). Enjoy the vegan desserts! XOXO Carine.

    I followed the recipe and even pulled the brownies 5 minutes early, and still found them too “cakey” for my taste. But I think cutting back a few more minutes and maybe upping the fat will help.

    Thanks for the recipe!

    • I am sorry this wasn’t to your taste Liz. I have got a fudgier low carb brownie recipe to try if you prefer fudge brownies. It is here. That is a recipe using a bit more fat – healthy one from avocado – and you should prefer this texture if you are not too much into coconut flour brownies. Enjoy the blog and recipes. Thanks for taking a minute to shre your valuable feedback ! XOXO Carine.

    • Hello ! If you follow the recipe using the ingredients listed, it will create a delicious low carb sugar free treat that should not impact your blood sugar level very much. I had pre diabetes and I was treating myself with a slice of this once in a while and I was fine. Enjoy the recipe and again, always check with a doctor if you have got any doubt on a recipe regarding your particular health condition. We are all different and I am not a medical professional, I wouldn’t give a bad advice to you. Have a great time baking those. XOXO Carine.
