Ingredients Tips

bowls full of brownie ingredients
  • chocolate – use a bittersweet chocolate for the best results. I use 95% cacao Lindt but anything for 70% up is best.
  • gold sweetener – I use Sukrin Gold sweetener. Other brands available are Lakanto, Natvia or So Nourished to name a few. Alternatively, use any keto sweetener that has a ratio of 1:1 with sugar and is also of a similar weight to sugar. If using something like Splenda you will need to adjust the sweetener as the weight measures are different.
  • unsweetened cacao – please don’t use the sweet stuff. It is loaded with carbs. My favourite brand is Cell Squared.
  • almond flour or almond meal – it doesn’t matter in this recipe. Either one will do for your keto brownie recipe to work out just perfect.

FAQs and Expert Tips

Can I make this nut free?

Yes, you can! Simply swap the almond flour for lupin flour or 3 tablespoons of coconut flour.

How do I store it?

simply keep in an airtight container in the fridge for up to a week or pack in a ziplock bag in the freezer.

Can I make this dairy free?

Simply swap the butter for a plant-based spread or coconut butter. I prefer coconut butter as it also adds more flavour to the brownie.

  • Breville Hand Mixer
  • 20 x 20 cm 8" brownie pan





  • Preheat oven to 170 ̊C. Line a 20cm x 20cm brownie pan with baking paper.
  • Combine half of the chocolate, salt, butter and sweetener in a saucepan and simmer over low heat until mixture is smooth. (Alternatively, do this step in the microwave).
  • In a large bowl add the eggs, and remaining brownie ingredients including the cooled chocolate mixture. Stir well to combine. Fold through the remaining chocolate chunks and nuts, if using.
  • Spoon into the prepared tray and smooth over the top.
  • Bake for 15-20 minutes. Brownie should still be very soft and fudgy. It will firm up upon cooling.
  • For the buttercream; place all ingredients into a mixer bowl. Using a stand mixer or hand mixer mix until the frosting is creamy and well combined. Spread over the brownie and cut into bars to serve.

  • For the buttercream; Mix all ingredients 1 min/speed 5. Scrape down sides of the mixer bowl. Mix for further 1 min/speed 5 or until smooth and fluffy. Spread over the brownie and cut into bars to serve.


  1. Chocolate – I use Lindt 95% cacao for this recipe. It is very low carb and sugar and has a delicious bitterness that balances with the sweetness. Use whatever chocolate you prefer.
  2. Almond Flour – use almond flour or almond meal. For a nut free brownie swap lupin flour or three tablespoons of coconut flour.
  3. Sweetener – I use Sukrin Gold sweetener in my brownies. Any white granular sweetener can be used as long as it is a 1:1 ratio of sweetness to sugar and check that the weight is the same as regular sugar or granulated sweetener before using.
  4. Storage – keep in an airtight container in the fridge for up to one week. Alternatively freeze in a ziplock bag.
  5. Alternative topping – if you do not want to make the buttercream simply dust with extra cacao and serve with cream or ice cream if preferred.
  6. Salt Flakes – I use sea salt flakes in this recipe. If using fine ground salt, table salt or Himalayan salt reduce to just a pinch as they are far saltier.
  7. Nutritional values include both the brownie and frosting.

    I have made many low carb/keto brownies in seven years. Megan’s new recipe takes keto brownies to a whole new level. Moist, gooey in the centre with a frosting that is divine. Definitely not too much nut meal and the big test MOORISH šŸ™‚

  • Diana M Ferguson says:

    l love your recipes. I would like to use gelatin instead of collagen but I’ve never used before. For the gelatin would I use the powdered gelatin that you buy in packets here in the States. Thanks.

  • Kristin Von Rump says:

    Love this recipe. I have tried numerous keto brownie recipes and this by far is the best…very chocolatey and moist.

  • Jill says:

    Hi The carb count for the sukin gold sweetener is 99 grams carb for a 100grams according to the label so not sure if the label is correct? Per slice Megan you say 3 gms of carbs

    Am I reading this incorrect

  • Jill Mottram says:

    Ok thanks that makes sense

    These are delicious. I’ve made them four times since I found the recipe; with nuts and without. I haven’t made the frosting yet, but they’re so good even without it!

  • Rose says:

    Hi Megan, I’m just wondering what the purpose of collegian/gelatin is in the brownies? I don’t have any collegian so would just use normal gelatin but I’m wondering if I leave it out of it will change the texture or flavour in any noticeable way?

    • Megan Mad Creations Hub says:

      Hi Rose, the collagen can add additional health benefits as well as a slight “chew” to the brownie. The gelatin is there also for the same purpose.

  • Kristine Lynch says:

    Hi Megan, I made this today but I still had a bit of butter on the top maybe this was due to not using a hand mixer do you think šŸ¤” smells delicious but still letting it cool down . Cheers
