The Best Low Carb Keto Brownie Recipe (2024)

This just may be The Best Low Carb Keto Brownie Recipe ever.

These are gooey, fudgey, moist, chocolatey..

They offer everything you love about traditional brownies yet are gluten free, sugar free and grain free.

I don't know about you but I've always loved fudgey, almost undercooked brownies.

Cakier brownies just seem like chocolate cake to me! Don't get me wrong, I also love chocolate cake…

But I believe brownies should be thick, rick and decadent. Not light and fluffy.

That's why this keto brownie recipe contains minimal leavening ingredients and minimal flour in it's base.

To start with a dry ingredient blend of almond flour, cocoa powder, arrowroot starch, espresso powder, xanthan gum, baking powder and salt.

Almond flour helps thicken the brownies while not taking away from their rich flavour. We use 1 cup because almond flour is much less absorbent than traditional white flour.

The cocoa powder is of course there to add chocolate flavour. Quality matters. I really enjoy using the Costco Rodelle cocoa powder as I find it has a nicer flavour.

As you'll see later though, these brownies also contain melted chocolate to intensify the rich chocolate flavour.

Next we add arrowroot starch. If you haven't heard of it, it's extremely similar to cornstarch except it comes from a root rather than corn. It's so similar though that you can sub cornstarch 1:1 if you do not have arrowroot starch.

The point of adding arrowroot starch is that it gives the brownies an almost pudding-like consistency in the center (but not to the extreme).

It helps keep them soft and gooey while the outside bakes.

Next we add espresso powder.

Espresso powder is always optional but it helps to intensify the chocolate flavour. Even if you aren't a big coffee lover, I'd suggest adding this ingredient just to see how you like it!

The xanthan gum in this fudgey keto recipe is also optional but highly recommended. I use it in almost every keto dessert.

This ingredient helps improve the batter's texture so that it can thicken and become more elastic like batter that contains gluten. This is super important in creating that signature “chewy” brownie texture.

The last ingredients in our dry blend for this low carb brownie recipe include baking powder and salt.

Baking powder is used in a small quantity to help give a little rise to the brownies. This recipe also only contains 1/4 tsp salt but if using unsalted butter, you'll want to increase that to 1/2 tsp.

In terms of wet ingredients in this fudgey keto brownie recipe, we use most of the basics…eggs, butter, vanilla extract and melted chocolate.

The chocolate chips I use in this “The Best Low Carb Keto Brownie Recipe” are called Krisda Chocolate Chips and are just 2g of NET carbs per tablespoon but you can also use Lily's Chocolate Chips, Choc Zero Chocolate Chips OR 90% dark chocolate if you prefer.

Finally, we have our sweeteners. Sweeteners I think can make or break a recipe. That's why I highly recommend picking up one or both of my recommended sweeteners for this recipe (if you can).

I've made this recipe with both a powdered monkfruit erythritol sweetener blend AND a combination of the powdered monkfruit erythritol sweetener blend + a sweetener called Allulose.

My favourite is the combination of the two sweeteners together but if you can only get one, the powdered monkfruit and erythritol blend is still delicious on it's own!

Allulose simply adds a chewiness to the brownies that you don't get with using the Lakanto sweetener on it's own.

They work well in combination because allulose offers a light sweetness while improving the texture of the brownies while the powdered monkfruit erythritol blend adds more sweetness similar to that of sugar.

All of these ingredients together are what make up these delicious fudgey and moist keto brownies.

Ingredients In The Best Low Carb Keto Fudge Brownie Recipe

–Almond Flour– I use the Kirkland Costco brand of almond flour (I buy it in bulk on Amazon or at Costco itself occasionally) for this recipe. As I’ve noted in many of my past recipes, the brand of almond flour can affect the final outcome of the recipe because absorbency can vary depending on how the flour has been processed.

–Cocoa Powder– I use theRodellebrand again from Costco. I find it to taste better than other brands!

–Xanthan gumThis is used to create a batter more similar to that of white flour. It helps give the brownies a chewier texture.

–Arrowroot Starch – Optional. Arrowroot Starch makes your brownies a bit more soft and silky. It does have 7g of carbs in a tablespoon but when spread throughout a recipe like this one it adds less than 1g of carbs to each brownie. If you leave it out, be sure to replace it with 2 extra tablespoons of almond flour. You can also substitute it with cornstarch!

–Powdered Monkfruit Erythritol Sweetener – I use the Lakanto brand currently. This sweetener tastes the closest to regular white sugar and blends seamlessly into baked goods.

– Allulose – Optional, I use this in combination with the Powdered Monkfruit Erythritol Sweetener to create what I believe to be the best possible flavour and texture for these brownies. Allulose bakes more similarly to real white sugar and creates a “chewy” texture but it's also less sweet than regular sugar so the Powdered Monkfruit Erythritol blend is used to make up for the lack of sweetness.

–Krisda chocolate-chips are what I use for the chocolate in this keto fudge brownie recipe as they are just 2 NET carbs per tbsp.. but you can also use 90% dark chocolate, Choc Zero Chocolate Chips or lily’s chocolate-chips.
