These brownies are the ultimate holiday treat. With less than 4 grams of net carbs and 170 calories per serving, they are the perfect after dinner dessert.

One of the ingredients I used to make these rich and fudgy low-carb brownies is avocado. It may sound like an unusual ingredient to some of you but it's definitely worth trying. It adds richness and heart-healthy monounsaturated fats. Don't worry, you won't be able to even tell it's there!

Apart from brownies, avocado works in other ketogenic treats like ice-cream. I used it in my Mint Chocolate Chip Ice-Cream, Key Lime Popsicles and Chocolate Popsicles.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

LOVE this brownie!!  Definitely something I've missed and most other keto brownie recipes just haven't been quite as satisfying!! I forgot to pay attention to the grams for the avocado and just added one but will definitely be making these again.  I also used bakers unsweetened chocolate, added additional Swerve and used sunflower flour because I can't have almonds.  Mine were probably a little dry from not adding enough avocado but have a wonderful dense texture and rich taste.  I can't believe this recipe is 2 years old and I've just found it!  Thank you for your amazing recipes and for the diet challenges that keep me on track!!

I made a batch of these brownies this afternoon. I didn't even wait until it had fully cooled to take a bite. Oh my goodness! The only way to describe these brownies...fluffy and light like a whipped truffle cake brownie! Absolutely the most scrumptious dessert I've enjoyed in a long, long time and I haven't even added whipped cream yet! Oh the anticipation! The only thing I did differently was use powdered Xylitol instead of Swerve. I've been using Xylitol for years now and in moderation so haven't experienced any of the typical side effects you hear about. Thank you for creating such a delicious recipe!

Cherylann, thank you so much for your lovely feedback!

Thank you so much for this and all your recipes! Made this today for the first time. The brownies are so tasty, better than the "real" ones I used to bake long long ago... I made a substitution, instead of cacao powder I used organic cacao fiber powder, which is available here in Germany in low-carb shops. You can substitute 1:1 and get the same results but lower net carbs as with regular cacao pwd 😉 Btw today I forgot the salt... you say it's a key ingredient, why? Only for taste oder is there another reason? Next time I won't forget 😉 the recipe is amazing and for sure I will make it again and again and again... thank you!

Reply

Thank you for your kind words and for the tip! Yes, the salt is only to taste (no other purpose). I'm glad you enjoyed!

Reply

I tried using Erythritol but it has an after taste.

Reply

Some people don't like the "cooling" effect of pure erythritol - you might want to try Swerve which is a blend of erythritol and FOS. I hope this helps!

Reply

Wondering what amounts I need to just use cocoa instead of chocolate squares. Thanks.

Reply

I'd guess you can add 1/2 cup cocoa powder, plus add 1/2 cup butter or coconut oil or cacao butter. I hope this helps!

Reply

Ummm... I used your recipe to fool my 40 year old son into eating something healthy with avocado. But I'm not sorry! If I had mentioned to him that it had avocado, he would have insisted that he tasted it. But I kept quiet. He LOVED the brownies. Even the very very picky grandkids loved the brownies. I topped them with an icing that I whipped up with butter, cream cheese, vanilla and powdered Swerve. Good stuff. I'll be making this again!

Oh that is amazing! I'm glad he enjoyed! Thank you for your lovely feedback

These are really really good. My family and I were super impressed!

Thanks so much for this recipe.  The first keto brownie that I tried was just awful, I took one bite spat it out and put the whole batch in the garbge😝.  The texture of these is great and they don't taste low carb.  This will be my go to recipe.

Thank you Donna, I'm glad you enjoyed!

Made them twice, delicious.  These are a favorite in my house even for the non keto eaters.  Second time made in a bigger pan, they baked better for me.  Very grateful for the ingredients being in grams, I had to use 3 small avocados to equate 200 g. I used Nativa sweetener. Thanks for the recipe, these are a great treat.

Thanks so much Kristi, I'm glad you liked them!

Love them....
I can't use Almond flour as I'm allergic to Almond. I use pecans that I grind down myself. The texture is crumbly but with a small dollop of thick double cream, it is a better alternative for me. I've lost almost 13kg in 10 weeks...and boy do I feel so much more alert and happy! Thanks for the amazing recipe!

Well done Farhana! Macadamia nuts are a good alternative too 😊

Hi, this recipe looks amazing, I'm going to try it tonight for dessert.  I don't have any dark chocolate though, do you think it would work with cacao nibs?  I also only have stevia powder/granules, would I only use about a tablespoon of this as I have heard that it can be quite bitter, or could I possibly use some vanilla bean paste?

Reply

Hi Clare, if you don't have dark chocolate, try more cacao powder + butter instead. Cacao nibs won't work. Stevia can be used as an alternative. It depends on the product but if it's pure stevia powder, it will be 200-300 times sweeter than sugar. If it's granulated stevia mixed with erythritol, then it should be as sweet as sugar. I think the best approach is to add sweetener at the end, taste and add more if needed. Vanilla bean paste contains sugar - I'd personally avoid it and use either vanilla bean powder or unsweetened vanilla extract. I hope this helps!

Is there any flourless version of this recipe?
I only have almond flour, how much almond flour can I substitute for coconut flour in this recipe?
Thanks

Reply

Although I haven't tried it in this recipe, in most baked goods you can substitute coconut flour with almond flour in 1: 3 ratio (for every part of coconut flour, use 3 parts of almond flour). In this recipe, it would mean that you should use 3/4 cup almond flour instead of 1/4 cup coconut flour.

Reply

Can I use only almond flour and also, omit the avocado?

Reply

Hi Maria, check out this recipe, it's from my KetoDiet cookbook: Fudgy Keto Brownies

Wow these came out so great! Didn't realize these would be so thick but thats fine because that means more brownie per serving for me!  They are very dense though and definitely taste of dark chocolate.  I uses 100% unsweetend dark bakers chocolate and used drops of stevia to sweeten.  Would like to see what I could do to make these just a tad bit less dense so I'm not grabbing a glass of water to get these down.  Any suggestions would be helpful. Kids devoured these like no tomorrow so absolutely making these again!

Reply

Thank you! I suppose you could use more almond flour and less of the avocado-chocolate mixture to make them more cake like 😊

Reply

I made these and they were so good. I did alter it a bit by only adding 1/4 cacao instead of 1/2 after reading a comment that it was a bit strong. I wasn't sure if I needed to replace the other 1/4 cup so I added defatted peanut flour hoping the peanut butter taste would come through but it didn't. Next time I might try adding 1/4 cup of oat fiber instead and see how that does.
If I omit 1/4 of of the cacao powder do I need to add something else in it's place?
Thank you!!!!

Reply

Sorry about the late reply - I just found your comment! I think you could use almond flour - or coconut flour instead. I'd go for 1/4-1/3 cup almond flour or 2-3 tablespoons coconut flour instead of the 1/4 cup cocoa powder. I hope this helps 😊

OMG I just made them and they are so good!
First I thought they will be dry but they are so moist.
Btw thank you for writing in the recipe the ingredients in gram as well - for me as a german girl it is much easier to bake 😊

Thank you Cristiana, I'm glad you liked them! 😊

I made these tonight to test out a new convection toaster oven that we bought. They are -perfect-. Thank you for such a great recipe! I used 100% instead of 85% chocolate and kept the same amount of erythritol and just a few drops of chocolate stevia. Absolutely delicious served with whipped cream and a dash of cinnamon.

Thank you Jody! 😊

Hi Martina,
These are delicious! I also calculated that these have more like  11 net carbs per serving, almost all from the swerve alone. My food database says that 3/4 cups swerve has 180 g of net carbs. Is there a different product I should be using?

Reply

Thank you Kimi! Swerve is almost zero-carb because it has no effect on blood sugar and is almost zero calorie. Here is more about sweeteners: Complete Guide To Sweeteners on a Low-carb Ketogenic Diet

I just made these brownies...YUMMMM!!! I did used Truvia baking blend, however, which does have some sugar in it. I didn't have a full bar of the 85% chocolate, so I used about 2 oz of 85% and 1.5 oz of unsweetened baking chocolate. I was trying to figure out how much of the Truvia baking blend to to use, so I just decided to use 3/4 cup like in the recipe, and I made the right call! It obviously ended up making calories and carbs higher, but sugars weren't bad. From my calculations using My Fitness Pal, each serving came to roughly 200 calories, 16.2g fat, 12.2g total carbs, 4.5g fiber, 1.2g sugar, and 5.6g protein. And honestly, one brownie was enough! Rich and delicious!

Thank you!!! 😊

I was very excited to try these. I used Ghirardelli 86% chocolate and I used stevia because I didn't have the other sweetener. Unfortunately these were SO strong dark chocolate tasting I couldn't enjoy them. If you really like dark chocolate you'd love them (so I'm sure my husband will enjoy!) I ended up making a cream cheese frosting for them and that helped a bit.
4 ounces cream cheese
1-2 tablespoon cream
1 1/2 tablespoon butter
stevia or other sweetener to taste
drop vanilla extract
--
Whisk until well combined.
I haven't been super low carb as long as most people so maybe that's my problem. Who knows? I might try these again in a few months.

Reply

Thank you for sharing your tips! I do have to admit these are for dark chocolate lovers, they do taste quite strong 😊 Maybe your palate will adjust in a couple of months, at least mine did. Or you can try 70% dark chocolate next time?

Reply

Please can I use these same recipe as normal chocolate cake recipes?

Reply

These may be a bit too dense/rich for a chocolate cake but you can always use cacao powder instead of chocolate and add some almond or coconut milk instead. I'm planning to make chocolate bundt cake - as soon as I find the time to do it 😊

Reply

Made these again and topped them with fresh cream that I whipped this morning.  I do have to say that having the right equipment makes so much of a difference when making food.  The Kenwood is just an amazing machine in the kitchen ☺️ This recipe always comes out great and has become a family favourite.

Reply

It definitely does! I think that my food processor and slow cooker were the best investments ever!

I made these last night and wow!  Pleasantly surprised at how good they were and how easy they were to make.  Checking today to see what else you have.  Looking for keto chocolate cookies

Thank you Donna! I'm actually going to post a recipe for 5-ingredient keto chocolate cookies tomorrow so stay tuned 😊

Thx so much Martina
Cooking this way also if you can believe it has also made me lose 10 pounds and really all it is was eliminating the white sugar and bleached white flour from my diet. My mummy tummy has also shrank, 👍🏽 my husband commented this AM that by simply me switching over to cooking this way he has noticed a significant drop not only in my weight but his chronic heartburn he suffers from 😀 I thanked him for the positive comment on my waste line as I devoured a brownie 😊
I believe eating this way which I consider to be 'anti-inflammatory ', really does help considerably in some of the ailments we suffer from big and small. Just wanted to say Thankyou for sharing your knowledge, if we all take the time to self educate, knowledge is truly power which benefits us and our families. Grow your own food and cook naturally as best we can. Now, onto chocolate donuts 😉

That's awesome news, I'm glad it works great for both of you! Thank you so much for your kind words and sorry for the late reply, I always have many comments to approve and reply to and I haven't done it for the last couple of weeks because I'm working on a new cookbook! 😊

Made these they were awesome!
Just wish I could print from the site a printer friendly version 😊

Thank you so much Janice! I'll definitely make a free eBook at some point 😊 You can print the recipes (see top of the post and "print recipe - full" or "print recipe -compact" - recommended).
