These keto brownies are super fudgy, gooey, and taste like the real thing! Ready in just 20 minutes, you won’t believe these are low carb.

If you’ve been around here for some time, you may remember that we’ve shared some classic keto desserts, including a keto cheesecake, keto ice cream, and a keto chocolate cake. None of them have been as easy as this.

If you are after the best tasting keto brownies recipe, you have come to the right place.

These brownies are a spin on my almond flour brownies and coconut flour brownies (or all my brownie recipes, to be honest). While both of these are low-ish in carbs, they aren’t completely keto-friendly. Not anymore- this recipe will swoon even the most reluctant low carber out there.

Recipe highlights

  • Fast. They take less than 20 minutes to bake and require little prep work.
  • Perfect texture. These brownies are gooey and fudgy in the middle and with those gorgeous crinkly tops. 
  • Incredible flavor. Full of chocolate and no grainy, bitter, or artificial aftertaste ever.
  • Seriously low carb. Each brownie has just 3 grams of net carbs and are also gluten-free and sugar-free.

Ingredients needed

If you’ve made any of my keto desserts before, you probably have everything on hand as we speak. If not, there is nothing special needed and you’ll find everything at any basic grocery store. Here is what you’ll need: 

  • Butter. Salted or unsalted. I prefer using the salted variety as it negates the need to add any extra salt. I tested these brownies with coconut oil but found the edges to be greasy.
  • Chocolate. Any sugar free chocolate works, including sugar-free chocolate chips or baking chocolate. The latter is a fantastic option as, even though it is extremely bitter, the brownie batter already has added sweeteners to compensate. 
  • Almond flour. Blanched almond flour is a must. It doesn’t leave a gritty texture and has a lighter crumb. 
  • Unsweetened cocoa powder. Sifted and unsweetened. 
  • Baking powder. The leavening agent to give the brownies some stability. 
  • Sugar substitute. The best sweetener to use is allulose, as it dissolves like sugar would. I have successfully tried my keto brown sugar too. I don’t recommend using erythritol, swerve, or stevia as it gives the brownies a super grainy texture.
  • Eggs. Room temperature. 
  • Vanilla extract. Optional, but highly recommended.

How to make low carb brownies

Step 1- Make the brownie batter. Start by combining the butter with half the chocolate. Microwave in 20-second increments until the both are mostly melted. Using a spoon, gently mix until smooth. Next, beat the eggs until frothy. Slowly mix in the butter/chocolate mixture until combined. Add the dry ingredients then fold through the remaining chocolate. 

Step 2- Bake the brownies. Now, transfer the brownie batter into a lined square pan. Bake the brownies for 14-18 minutes or until a skewer comes out mostly clean. Let the brownies cool in the pan for 20 minutes before carefully transferring to a wire rack to cool completely. 

Recipe tips and variations

  • Do not over-bake the brownies, as they will continue to bake as they are cooling down. If you’d like more cakey brownies, you can cook them closer to the 18-minute mark.
  • Sift your dry ingredients if there are clumps throughout. 
  • Don’t fret if the brownie batter looks a little thick. It is supposed to be like that and will bake as expected.
  • If you don’t use allulose, your brownies won’t have the crackly tops. Allulose is the only sweetener that will yield it. With that said, I’ve tested these brownies with monk fruit sweetener and Splenda and they taste just as good.
  • Fold through chopped walnuts, pecans, other kinds of chocolate (like white chocolate!) or even low carb fruit (like berries). 
  • Swirl through some peanut butter to make keto peanut butter brownies.

Storage instructions

To store: These brownies can be stored at room temperature, provided you intend to consume them within 3 days. Ensure they are in a sealed container or covered on a plate. If you want them to keep longer, store them in the refrigerator.

To freeze: Wrap the brownies in parchment paper and place them in a ziplock bag or shallow container. They will keep fresh for up to 6 months.

    These were good!I had to bake for 35 minutes. I used swerve sugar and earth balance butter. Also I live at a higher elevation (4800 feet) so that might be why it took longer.

    Wow, so good. I used 2ozs baker’s chocolate (half melted in butter, half chunked up and folded into batter) and didn’t add any extra sugar, and it was still perfectly sweet. I also ran into the same issue as one of the other commenters with very soupy batter after 18mins, but then I turned the heat up to 375F and cooked for another 10mins and it was perfect. We tried one 20mins after they came out of the oven, delicious, but when we tried one the next day, hot damn, were they even more delicious. I honestly don’t think any non-keto people would even tell the difference. Thanks!

    Oh YUMMMM! These are amazing! I made them to take to the camper to share and they disappeared within minutes! Even people who claim to not like keto foods ate them and said how good and fudgy they are. These are so easy to put together and once they cool completely are easy to handle without falling apart. They did take me about 10 minutes longer on baking but otherwise I had no issues with these.

  4. Hello- I made these last night and while they did turn out pretty good, the sugar didn’t seem to dissolve, is that normal? I used lakanto monk fruit sweetener And followed the recipe exactly, except for the chocolate chip part because I didn’t have any, so I added a tablespoon of cocoa powder to the melted butter. The fudginess is on point and so is the flavor, it’s just the crunch from the sugar crystals that throws me off. Any ideas as to why that happened or how to avoid in the future?

    1. Hi Lena! We’ve sometimes found Lakanto sweetener are larger than other brands, so to combat it, if you blend it until a finer consistency (like superfine sugar) you won’t have that issue 🙂

  5. I’m a diabetic so I can’t have any of that sweetener because it jumps my sugar up I can’t even have the vanilla so can I still make them without the sweetener and the vanilla.

  6. Really, really delicious! I There was no butter, so I substitute the butter for thick cream and added a splash of coconut oil, heated the mixture and then added it to the chocolate chips to melt. Love your recipes!!!

  7. These brownies are incredible! By far the best I’ve ever had let alone made. So gooey and chocolatey. My families always very sceptical of my “healthy bakes” but they loved there!
