Low carb brownies are one of my favorite keto desserts and over the years, I've tried so many different keto brownie recipes that I've lost track!

I published this post in 2019 but have since updated the original recipe to get it just right. There are also new photos and recipe tips to bring you the very best content, always.

why this keto brownies recipe works

This is a coconut flour brownies recipe sweetened with monk fruit and made with a mix of grass-fed butter and almond butter for extra gooey, fudgy-ness that's just like regular brownies.

Dutch-processed cocoa powder and stevia-sweetened dark chocolate chips are where the "double chocolate" part comes in. 🙂

Essentially, this is a great recipe if you're craving healthy brownies that taste just like the real thing but with an added bonus: they're not only super chocolate-y and delicious, but they can work for all eaters!

Since they're refined sugar free / low-sugar, they're the perfect brownies for diabetics, low-carb and keto eaters, i.e. anyone looking for delicious desserts that are low glycemic.

And if you're dairy-free, you can substitute the butter for melted coconut oil, more almond butter, peanut butter or a seed butter like tahini.

Here is a quick summary of the steps, but for the ingredient amounts and instructions in this keto brownies recipe, view the recipe card at the bottom of the page.

In a large mixing bowl or bowl of a standup mixer, mix the melted butter, almond butter and granulated sweetener.

Whisk stirring wet ingredients for keto brownies recipe.

Whisk in wet ingredients- eggs, vanilla and coffee.

Add the dry ingredients in a separate medium bowl (except the chocolate chips) and mix well to combine. Pour the dry ingredients into the bowl and mix. The batter will be extra thick but it should still be pretty easy to spread. Stir in half of the chocolate chips.

Transfer the brownie batter to an 8x8 baking dish lined with parchment paper. Spread it evenly across the base and sprinkle the remaining chocolate chips.

Transfer the brownie pan to the preheated oven and bake for about 20-24 minutes. Remove and enjoy warm (for extra gooey brownies) or allow them to cool to room temperature for more firm brownies.

substitutions

You can easily modify this coconut flour brownies recipe a little bit so it fits your eating style! Here are a few swaps you can make.

Dairy-free brownies: Omit the melted butter and sub the same amount of melted coconut oil, almond butter (for 1 cup total), all-natural peanut butter or tahini for a deliciously nutty spin.

Paleo coconut flour brownies: Use coconut sugar instead of granulated monk fruit sweetener and substitute melted coconut oil for the butter.

Different sweeteners: I prefer granulated Golden monk fruit sweetener but you can also use granulated allulose (increase the amount by 2-3 tablespoons), plain erythritol or another ketogenic diet friendly sweetener that's a 1:1 sugar substitute. If you're simply looking for a gluten-free or low sugar brownies recipe, you can swap in regular sugar for granulated monk fruit sweetener and they'll turn out great.

keto brownies recipe tips

The brownie batter turns out to be super thick- even thicker than batter for regular brownies. This is to be expected!

The baking time may vary based on your oven, but I usually bake these for about 22 minutes. They will look slightly underdone, especially in the center, but that ensures they will still be very gooey and fudgy once they have cooled to room temperature. Tip: When they're right out of the oven, the consistency is very similar to chocolate lava cakes. 🙂

Store these low-carb brownies in an airtight container at room temperature for up to one week.

Dutch-processed cocoa powder has a more smooth and intense chocolate flavor that will give you the best brownies! If you're using unsweetened cocoa powder that is not Dutch processed, you should swap the baking powder for baking soda. Regular cocoa powder is more acidic than Dutch-processed powder and baking soda helps to balance out the taste.

Feel free to toss in other add-ins, like chopped pecans, walnuts, or coconut flakes. A few drops of peppermint oil is also ideal if you're baking these during the holidays.

frequently asked questions

How many carbs are in a keto brownie?

These coconut flour brownies are low in carbs, with only 4 net carbs per serving! They do contain sugar alcohols from the granulated monk fruit sweetener but that does not factor into the final net carbs of this keto recipe since the net carbs of monk fruit sweetener ends up being 0.

What are keto brownies made of?

This sugar free brownies recipe consists of coconut flour, a monk fruit sweetener blend and Dutch-processed baking cocoa as the main dry ingredients. Butter, almond butter and eggs are where the moisture comes in. A splash of strong coffee and vanilla help add flavor and sugar-free chocolate chips are that little extra that take these keto brownies to the next level.

What can replace sugar in brownies?

Golden granulated monk fruit sweetener from Lakanto (affiliate link) is my favorite sugar alternative to use in this easy keto brownie recipe. It has a caramel-y flavor and unlike other erythritol sweeteners, the cooling aftertaste is very minimal! If you're not a fan of erythritol, you can also swap in granulated allulose or coconut sugar. It's important to note that while coconut sugar is paleo-friendly, it's not an ideal sweetener if you're looking to make these brownies for diabetics or other eaters who need a low-glycemic option. Monk fruit sweetener or allulose are better options.

Is coconut flour keto friendly?

Absolutely! Coconut flour is high fiber, low-carb and overall, a wonderful type of gluten-free flour to include in keto baking. It can be trickier to work with since it's highly absorbent, which is why this coconut flour brownies recipe only calls for 2 tablespoons total!

Can I substitute coconut flour for almond flour?

Coconut flour and almond flour work very differently and cannot stand in for each other as a 1:1 replacement.
