These easy, fudgy keto avocado brownies are a feast for your taste buds! A deliciously gooey flourless brownie base, topped with a silky-smooth chocolate avocado frosting... yours with only 15 minutes prep.

I was on the fence about avocado brownies for a long time. Over the years, I tried a few times to create a recipe I was happy with, but never got it quite right.
Until today! I am so happy that I can finally share with you an avocado brownies recipe that can rival these fudgy keto brownies.
Pinky promise, you cannot taste the avocado at all!
It helps create a fudgy yet light texture in the baked base and it is perfect for a silky-creamy frosting that won't sit in your tummy like a rock.
I love avocado desserts and have made chocolate avocado cake, chocolate avocado mousse, these keto avocado chocolate cookies and even chocolate avocado ice cream.
But I think this avocado brownie recipe may be my favorite yet!

Ingredients

Here are our ingredients:
- Avocado - Must be ripe and soft, with green flesh and without dark spots.
- Almond flour - I used ground almonds, but super-fine almond flour is also fine.
- Eggs - room temperature
- Sweetener - I used Lakanto Golden, which is a brown sugar substitute made with erythritol and monk fruit. For the frosting use powdered sweetener.
- Almond butter - This adds more depth and also helps with a fudgy texture.
- Cocoa powder - should be unsweetened
- Sugar free chocolate chips - Or use 85% or 90% dark chocolate. Note - if you use a 90% dark chocolate, you may want to add an additional 1-2 tablespoon of sweetener.
See the recipe card for full information on ingredients and quantities.
Recipe Variations
Any sweetener works in this recipe, from allulose to xylitol. If blood sugar is not a concern, you can even use coconut sugar.
For a dairy free version, simply use coconut oil in place of the butter.
Nut-free: Use 3 tablespoon coconut flour instead of the almond flour. Alternatively, replace the almond flour 1:1 with sunflower seed flour.
More flavor: Add 1 teaspoon of vanilla extract to the batter.
Instructions
It is surprisingly easy to make keto avocado brownies. Here are the basic steps.
For detailed instructions, scroll down to the recipe card.

Step 1: Place the chocolate chips in a heat proof bowl. Then, melt them on a medium heat over a pan filled with a little water until smooth. Or, use a microwave.

Step 2: Place all the brownie ingredients in a food processor and blend until smooth.Ā

Step 3: Spoon the keto avocado brownie batter into a parchment paper lined baking tray and level with a spatula.

Step 4: Bake in the oven until a slight jiggle remains in the centre.
Allow to cool in the pan for about 15 minutes and then remove to cool at room temperature.

Step 5: Place all the frosting ingredients in food processor and blend until smooth.
Taste and adjust the sweetness if necessary. I don't have much of a sweet tooth so you may prefer another 1-2 tablespoon of sweetener.
Use a spatula to add the frosting to the avocado brownies. Then, slice into 16 and serve.
Expert Tips
I made these brownies several times before they were perfect. Here are my top tips:
Melt the chocolate slowly. Never, ever heat it until it bubbles, or you risk that it splits and curdles. The water bath method is the safest. If you use a microwave, stop before the chocolate is fully melted. Remove and stir until it is liquid.
During the mixing process, scrape the sides of the mixing bowl a couple of times. This ensures that you don't end up with green avocado bits in the batter of in the frosting.Ā
And here's the most important tip: don't over-bake. This counts for brownies with avocado and ANY other low carb brownies. Take them out of the oven when they are still jiggly in the middle. A toothpick inserted should be sticky with dough.

Recipe FAQs
Yes, they are. This recipe is gluten-free and sugar-free. And of course, it contains avocado, which is full of nutrients and healthy fats. Find out more about the health benefits of avocado here.
It should be possible to use 2 flax or chia eggs instead of the eggs. Note I have not tried this yet.
No. Using both chocolate and cocoa powder gives the best results. Chocolate helps with the creamy texture and the powder lends depth. So, I do not recommend to leave either of them out or replace one with more of the other.
Of course. The frosting is not essential, but I recommend it.
Store your brownies in the fridge for up to 5 days in an airtight container or freeze for up to 3 months.Ā Freezing lightens the colour of the frosting a bit. However, it returns to normal once it is defrosted.

Why do you keep listing monk fruit and allulose knowing full well in the UK it's just not obtainable for most people here??
Katrin Nürnberger
Hello Ruby, if you type "lakanto uk" into your browser, you'll get results where you can currently purchase it in the UK. There are several online companies that sell it. Allulose is available via iherb.com.
Hope that helps!

Love these brownies!! They are so satisfying and yummy. When I make them, we limit ourselves to one/day per person. They're fabulous on my low-carb diet and have helped me keep my weight down. It's so nice to eat something so rich and fudgy and know that they are actually healthy!
Matia Bryson
Great recipe!, I've made it twice. The second time, to save time, mess, and cost, I omitted the almond butter and chocolate chips. It turned out fine. I'm also lazy about making frosting and I only sift powdered Swerve (erythritol) over it to make it look prettier. 5 stars!
Pascale
Oh, so tasty! I used xylitol and Besti brown sugar as I had no Lakanto. Took significantly more. Nonetheless they turned out sooo good!
As I had only two avocados I made half of the recipe and filled the dough in muffin liners. Made 8 muffins..
Love that recipe!

Just wondering what the purpose of the Almond butter is in the recipe? I don't normally stock this in my pantry. It is expensive for just 2 tablespoons. Is it essential? Thanks so much for educating me on almond butter.
Katrin Nürnberger
Hi Sarah, the almond butter is not essential. You can probably replace it with an additional tablespoon of butter and 1 tablespoon additional almond flour.
Sarah Sutcliffe
These are the most delicious brownies ever. Family & friends love them and have no idea they are keto. Many have asked for the recipe
Michael
What's an acceptable American substitute for Lakanto?
Katrin Nürnberger
Lakanto is an American company and you can order their sweetener online (links are in the post). You can replace it with any other sweetener of your choice that is a 1:1 sugar substitute. Swerve, for example, or allulose.

I got a fantastic chocolate hit from these keto avocado chocolate brownies. I subbed fleggs for eggs and double cream instead of melted butter and cocoa butter instead of almond butter. I added vanilla extract and a dash of monk fruit liquid sweetener as well as the brown erythritol and I didnāt use a food processor to mash the avocado I used a standard potato masher. I didn't make a topping because I was confident to undercook due to not having eggs and so the brownies were gooey and wonderful.
Yum
Diane
Iāve frozen avocados in the freezer could I use these do you think
Katrin Nürnberger
I think that should work. Make sure they are not watery after defrosting. Maybe pat them dry.
Esther Zielke
OMG!!!! These are totally AMAZING!!! I've had this recipe bookmarked for over a year, but just came across it again & had to try it... And I'm so glad I did!!
I ran out of Avocados for the base in the middle of everything, so did a quick search for replacement: needed 130 g still, substitution was 1/2 amount of cream cheese, so used 65 g of cream cheese... They seemed to turned out fabulous!! I couldn't wait til tomorrow to go buy more avocados for the frosting, so had 1 while they were still a bit warm... HEAVENLY!! Just a bit on the sweet side, so next time I will probably 1/2 the sweetener. I used Swerve Brown Sugar, so maybe that was why.
Fabulous!! Thanks so much for creating these!! And so incredibly healthy!!
