How to make Keto Brownies Recipe?

  • Preheat oven to 350 degrees F. 
  • In a medium bowl, melt together the butter, and set aside. 
  • Next, combine the melted butter with the sugar replacer. 
  • Then, combine with eggs, and add all the dry ingredients to them. Using a mixer, combine them all together until mixed through. You could also use a whisk. 
  • Next, transfer the batter to a pan, and bake for about 20 minutes. Make sure not to overcook it. A nice way to check if done is to insert a toothpick. If it comes out moist, it is ready. 
  • Let it cool for 20-30 minutes prior to consumption.

Can you replace almond flour with coconut flour?

Yes. We recommend using almond flour as it has a nicer texture, and works best for this recipe. However, if you are short on the almond flour, feel free to replace it with coconut flour.

Also, you can mix the two together. Just remember, that coconut flour absorbs liquid faster, and sometimes the brownies might end up a bit dry.


Ensure the brownies are cooled prior to cutting. Then, using a sharp knife cut them into about 3 by 3 inch wide. You can also grease the knife by spraying the blade with some cooking spray. This way, the blade glides through the bars easier. Also, wipe down the knife between cuts as the brownies tend to stick to the knife. 


The best way to store them is in an airtight container. Prior to storing them, ensure they are completely cooled. Then, transfer the pieces to an airtight container, and store in the fridge for up to 5 days. We recommend reheating them for a few seconds in the microwave. This way, they will be warm and moist, just perfect to enjoy!


Absolutely! Layer them in a freezer proof container and store in the freezer for up to 3 months. Also, it is a good idea to layer them in foil and then wrap them in plastic. This way they will maintain the moisture and texture better. 

To thaw them, remove them from the freezer and place them on the counter the night prior to eating.

Recipe Tips:

  • It is very important not to over-bake the brownies. So check on them after about 18-minute mark. It is better to have them slightly undercooked than dried out. 
  • Also, use room temperature eggs. This is also important when mixing the eggs with the butter mixture. If the eggs will be cold they might make the batter thicker, which will affect the end result. 
  • Since these are chocolate brownies, use sugar-free chocolate chips for a more pronounced chocolate flavor, but keep in mind, they may add a few more grams of carbs.
  • If you stored them in the fridge, it is best to reheat them for a few seconds in the microwave. This step will make them moist and tender, just the way they should be!
