Its the best way to treat the whole family to gluten free keto desserts that will satisfy chocolate cravings and sweet tooth cravings without compromising dietary goals.

I keep this keto recipe simple and do not use any wheat flour, or all purpose flours to make these low-carb brownies. 

I use the fudgy capabilities of eggs and cocoa combined to create the best recipe.

As with all of my other recipes, I stick to treats that are not only low carb, but gluten free as well.

So let’s get out the ingredients we need to make this delicious chocolate fudge brownie.

What you will need to make these Gluten Free Fudgy Brownies

• Butter; softened
• Confectioners erithrytol or other powdered low carb sweetener
• Cocoa powder
• Large eggs room temperature
• Pure Vanilla extract
• Almond flour 
• Baking powder
• Sugar free chocolate chips
• 8×8 pan
• Parchment Paper

It is time to make these Easy Keto Fudge Brownies

Preheat oven to 350F and prepare your 8×8 baking dish by lining with parchment paper.

This ensures that you are able to lift your prepared brownies out of the pan to cut cleanly on a cutting board once cooled.

Since we are mixing everything up in one bowl, there is no need to mix up the wet ingredients and dry ingredients separately.

Now put your eggs in a bowl filled with hottest tap water and set aside.

This warms up the egg so it does not solidify the fat used in the recipe.

In a medium saucepan over low heat, melt butter and confectioners erithrytol and whisk until well combined.

Watch it as the melted butter takes a bit of whisking to combine with the powdered sweetener.

Once it is whisked in smooth, slowly incorporate the cocoa powder into the butter mixture until smooth.

Remove from heat and let sit 5 minutes to cool a little bit.

Now whisk in the vanilla and eggs one at a time until a very smooth batter is made with a shiny top.

This step is what improves the texture of the brownies to be fudgy.

Now whisk in the almond flour and baking powder until very smooth.

Lastly stir half of the dark chocolate sugar-free chocolate chips. 

It is the secret ingredient that brings out the fudginess of these delicious brownies.

Spread in your parchment lined prepared baking pan.

Sprinkle other half of chips over the top of the batter.

Bake for 20 minutes at 350F until it is set in the middle and a toothpick tested in the middle comes out with a few crumbs or clean.

Check a few minutes early to not overcook them as oven temperatures vary slightly in how hot they cook.

Cool them for 30 minutes before lifting out to cut into 12 squares.

Store in the fridge in an airtight container.

If you are wanting to re-warm them, they can be reheated in a 350F oven for 5 minutes for ultimate fresh taste!

To freeze, wrap individually in plastic wrap then store in a freezer bag up to 2 months.

The recipe by itsself WITHOUT CHOCOLATE CHIPS is as follows for 1/12 of the recipe: 1.3 g total carbs/0.7g fiber/0.6 g net carbs/1.7g protein/ 11.2g fat

Tips, Substitutions, and FAQs

Here are some ways you can transform these regular brownies into something spectacular:

• Try turning this easy recipe for keto chocolate brownies into a tropical delight with my keto caramel recipe plus coconut for an amazing Keto Samoa Brownie.

• Make whoopie pies out of my favorite brownie recipe when you bake in a 11×15 jellyroll pan. Cut into small squares then half the squares lengthwise to make two halves. You would then fill it with my The Best Gluten Free Vanilla Buttercream Frosting. The texture of the fudgy chocolate brownies plus the frosting gives you the perfect bite and it holds together well. It is the best idea for an edible gift for a birthday or holiday celebration.

• Put this brownie recipe in the bottom of a lined 10 inch cast iron skillet and drop dollops of my Keto Chocolate Chip Pudding Cookie dough on top to create my Keto Gluten Free Cast Iron Skillet Brookie Recipe.

• You can also transform it into a layered dessert, perfect for potlucks or family gatherings, made with a layer of easy keto brownies, low carb chocolate pudding and a creamy whipped topping layer in my Keto Brownie Delight Dessert!

• Use this keto brownies recipe as a base to hold chunks of your favorite candy bar. I make homemade Keto 3 Musketeers Candy Bars, cut them into chunks, then stir in right before putting in the oven to bake! This turns out so decadent and very chocolate filled.

• If you are watching your sodium intake, you can use unsalted butter. Make sure to put just a tiny pinch of salt in the batter so it still has a bit of salt.

• Turn these into Keto Peanut Butter Brownies when you sub half of the butter called for with peanut butter. You can also use almond butter if you have a peanut allergy.

• Turn these keto brownies into Keto Cheesecake Brownies next time when you take 2 oz of cream cheese, mix with 1 egg and 1 tablespoon of tapioca starch then swirl this mixture into the prepared brownie batter before baking. Plop the cream cheese mixture into a cobblestone pattern then run a butter knife through it swirling. The less swirling the better as you want to make sure the brownie batter surrounds the cream cheese addition. If you have too many swirls then the brownies will fall apart at the cream cheese swirl.

Can I substitute in chopped chocolate bars for the chocolate chips asked for?

Yes, of course! You can use any additions that you feel like using.

Just simply stir into the brownie batter right before putting into the baking pan.

Do not leave them out as the added bits of melted chocolate when the brownies bake, makes the best texture shine through of ultimate fudginess!

Can I use coconut flour instead of almond flour in this recipe?

No, it cannot be substituted. Coconut flour requires a lot more moisture and your brownies will turn out very dry and crumbly if you do.

Do not add in heavy cream or almond milk with coconut flour if you try to substitute anyway.

It will be a runny mess if you do. 

Almond flour is ground almonds without the skins, resulting in a fine, light flour that lends a delicate nuttiness to your brownies.

This flour also helps achieve the fudgy texture you crave, while keeping your net carb count low.

What’s the difference between confectioners erythritol and regular erythritol? 

Confectioners erythritol is finely powdered, making it ideal for baking as it dissolves more easily.

If you only have regular erythritol, you can pulse it in a blender or food processor until it reaches a powdered consistency so it is the texture of the real thing.

Can I replace butter with coconut oil?

Yes, you can substitute coconut oil for butter in this recipe. 

Coconut oil imparts a hint of coconut flavor, which can be a delightful addition to your brownies.

Make sure you add in a pinch of salt to counter balance the sweetness since coconut oil does not naturally contain salt.

Can I replace the butter with cocoa butter?

​Technically you can. I say technically as I have not tried this in my brownie recipe but I HAVE tried this in my Easy Keto Dairy Free Blondie Recipe (gluten-free).

In this particular recipe, the cocoa butter instead of the butter made it more chewy and dense.

It is worth a try though!

Make sure you measure the cocoa butter after you have melted it, or weigh it out to the 4 oz called for in the recipe then melt.

Is there a sugar substitute or sugar alternative other than erythritol I can use?

Yes, you can use other sugar substitutes like monk fruit, stevia, or allulose. Just be sure that you are using a powdered version so you do not get grainy brownies.

Do my eggs have to be room temerature before adding them?

Yes, it is most important to have not only exact measurements on your dry ingredients, but also that your eggs are room temperature.

If you add cold eggs to the batter it will sieze up the butter or oil you used and not blend as well.

To achieve room temperature eggs without waiting, simply place them in a bowl of hot tap water for a few minutes.

This step ensures that your eggs integrate smoothly into the batter, contributing to the fudgy texture of your brownies.

Can I use regular powdered sugar instead of erythritol for non-keto brownies? 

Yes, you can use regular sugar, powdered,  if you’re not following a low-carb or keto diet. Just substitute it in a 1:1 ratio for the erythritol.

Do I need to use Dutch process cocoa powder?

While Dutch process cocoa powder can enhance the flavor and color of your brownies, you can use any unsweetened cocoa powder you have on hand.

I prefer to use cacao powder for the boost of anti-oxidants it provides.

How can I achieve the fudgiest texture in these brownies?

To make the fudgiest brownies, avoid overbaking. The toothpick test is your best friend; look for a few moist crumbs to indicate they’re done. Also, let them cool completely before cutting for the best results.
