Delicious Keto Brownies!

Hi Bold Bakers!

As Bigger Bolder Baking‘s resident alternative baker, I am here to show you guys how to take those classic sweets we all love and make them your way. Lots of people are trying a ketogenic diet and having great success, feeling satisfied and fit at the same time thanks to a high-fat, low carb and low sugar diet.

The thing is, whether you’re giving a keto diet a try or not, these are some of the best brownies around. These babies are beyond decadent with a deep chocolatey flavor, thick fudgy center, and big chunks of melted chocolate. By using some staple sugar substitutes I swear by, and lovely coconut oil, I was able to create the Best Fudgy Keto Brownies that are high in healthy fats, but very low in carbs — and best of all, 100% sugar-free.

If you are keto and think you need to cut out all sweets and indulgence, you are wrong! These brownies are here for you!

How to make a brownie Keto

So, while you might think making a fudgy brownie keto (that also tastes great) is hard to do, with the right ingredients it really is foolproof. My Best Keto Fudgy Brownie recipe is made with no sugar whatsoever as it uses an all natural sugar alternative and sugar-free vegan chocolate.

My favorite sugar-free chocolate brand for baking and just snacking is Lily’s Sweets. That said, any sugar-free chocolate brand will work! The other component to making the Best Fudgy Keto Brownie is making sure they are high in healthy fat. Brownies already lend themselves to a high-fat content, so 1/2 cup of coconut oil used in this recipe was the perfect fit. This keeps the brownies moist and super rich and makes sure you stay full and satisfied.

How to make almond flour?

What makes these Fudgy Keto Brownies low in carbohydrates is almond flour instead of a wheat-based flour. Gemma has a great method for how to make your own almond flour. For those that don’t know, almond flour is simply made by grinding almonds into a fine powder. The almond flour keeps these brownies low carb and also adds additional healthy fat and lots of texture to the brownies.

What is Lakanto MonkFruit Sweetener?

The secret ingredient in my Best Fudgy Keto Brownies is Lakanto Monkfruit Sweetener. This is my absolute favorite sugar substitute. This article isn’t even sponsored, this is just honestly a staple ingredient I use in all of my baking and cooking.

Whether you’re trying a ketogenic diet or not, it’s always good to have a sugar substitute handy. This one is the only one I have baked with that has the exact same result as sugar. This Lakanto Monkfruit Sweetener can replace sugar in all of your baking with a 1:1 ratio, it has no aftertaste, and caramelizes just like sugar would!

Will these keto brownies crumble?

These brownies really live up to their name. What makes these the Best Fudgy Keto Brownies is that they have an identical texture and flavor to a classic brownie made with sugar and flour. These keto brownies come out so rich, thick, and decadent. I really want to encourage everyone to give this recipe a try as it’s not just for people who are keto but anyone who is a chocolate lover looking for new ways to try the quintessential brownie!

For everyone getting a grainy texture try using super fine almond flour or buzz it in a bullet..also used powdered can buzz swerve or monkfruit in a bullet as well. Also do not over bake..if they are a little jiggly in the middle it’s all good they will set up as they cool..hope that helps

Use the choc zero chocolate chips for the chocolate, and the net carbs drop significantly.

We cut the tray into nine brownies, and each had <3 carbs

Changing that one thing would bring the net carbs to 1.6 using your serving sizes.

Hi Gemma, this recipe is just lovely! I tried this recipe, some of the best brownies that I’ve ever had. Thank you. I was wondering if I could substitute banana for sugar/oil.

Hi Gemma, I want to make this for my parents but don’t have almond flour. Can I use coconut flour instead?

Hi Gemma,
Can I use coconut flour as a substitute if there are allergies to other nut flours like almond? If so, does the amount of flour used change?

Hi! Where I live. It’s not very easy to get keto substitutes and the ones you. Get are very expensive. So one day I saw coconut flour and coconut sweetener in a store and i bought the on a whim, but now I don’t really know how to use them. Will they do for this recipe??
