These easy one-bowl keto brownies have a secret ingredient to make them extra fudgy and chewy. This might just be the ultimate keto brownie recipe and no one can tell they are low carb and gluten-free. At less than 4g total carbs, you can dig in with gusto!
Remember some time ago when I promised to bring you more basic keto recipes on this blog? Well these super fudgy keto brownies are part of that promise.
I love baking more elaborate creations and proving to the world that the keto diet it anything but restrictive. But sometimes I forget that simple and straightforward can be just as delicious.
So let’s skip the fancy stuff and get down to basics again!
Why you’ll love this recipe
The secret to the perfect texture is the addition of a little gelatin. I figured if it helps make my keto ginger molasses cookies chewier, it couldn’t hurt to try adding it to brownies, right?
And it really works! These keto brownies have all the best features you’re looking for, with a dense, rich texture and a slightly crackly top. They’re incredibly easy to make too. It takes a single bowl and 35 minutes from start to finish.
And readers swear that no one can even tell they are keto. I call that a win.
Ingredients you need
- Butter: Use unsalted butter and make sure to let it cool a bit before adding the sweetener and eggs.
- Sweetener: I recommend Swerve or another erythritol-based sweetener for this recipe. Using another sweetener will change the texture and consistency. Learn more about keto sweeteners here.
- Eggs: Large eggs are the standard for baking.
- Vanilla extract: Vanilla always brings out the chocolate flavor.
- Almond flour: Make sure you are using a finely ground almond flour for the best consistency. I also have a coconut flour brownie recipe, if you prefer.
- Cocoa powder: I prefer Dutch process cocoa powder when baking keto brownies. It has a deeper, richer chocolate flavor, but you can use natural cocoa powder if you prefer.
- Grass fed gelatin: Grassfed gelatin is the best choice for this and other keto recipes, but you can use Knox gelatin. Use 1 envelope for the brownies and make sure you add it along with the dry ingredients. You can also omit it completely but the brownies will be less chewy.
- Chocolate chips: Make sure to choose keto-friendly chips like ChocZero!
- Pantry staples: Baking powder and salt.
Step by Step Instructions
1. Whisk together the wet ingredients, including the butter, sweetener, eggs, and vanilla extract. Sweetener goes in with the wet ingredients so it dissolves better.
2. Add the almond flour, cocoa powder, gelatin, baking powder, and salt and whisk until well combined. Always add the gelatin powder with the dry ingredients before adding any water so that you don’t end up with blobs of gelatin in your brownie batter.
3. Stir in the water a little at a time to thin the batter to a thick but pourable consistency. You may not need the full amount of liquid to thin the batter – it depends on your cocoa powder and how absorbent it is. The batter should be the consistency of conventional brownie batter. Stir in the chocolate chips or chopped nuts, if using.
4. Spread the batter in a greased 8×8 inch metal baking pan and bake at 350ºF 15 to 20 minutes. If you prefer cakier brownies, continue baking for another few minutes until the center is fully cooked through. Let the brownies cool completely in the pan.
Recipe Tips and FAQs
This is a basic keto brownie recipe that you can customize and add your own fun twists to. Try these delicious ideas:
- Stir in ½ – ¾ cup chopped walnuts or pecans.
- Use brewed coffee instead of water to enhance the chocolate flavor. Or add some espresso powder for a mocha flavor.
- Add some different flavors of keto chocolate chips, such as white chocolate, peanut butter, or mint.
- Add some keto chocolate frosting or chocolate ganache.
- Drizzle with some keto caramel sauce for a decadent treat.
Use a metal baking pan. Ceramic and glass don’t conduct heat as efficiently as metal, so they will take much longer to bake through and firm up properly.
For fudgy keto brownies you will need almond meal, swerve sweetener, butter, eggs, cocoa powder and dark chocolate chips. My secret ingredient to making these brownies chewy is the addition of grass fed gelatin.
This brownie recipe is tested with almond flour and you can not simply swap out with coconut flour. You can, however, substitute with sunflower seed flour for a nut-free version.
For one 2-inch square, these keto brownies have only 1.2 grams of net carbs. Best of all, they taste as good as regular brownies, so you won’t miss the carbs at all.
Store the brownies in a covered container on the counter for up to 4 days, or in the fridge for a week. They can also be frozen for several months. Store them in an airtight container to avoid freezer burn.
Swaps and substitutions
- Dairy-free Option: Substitute the butter with melted coconut oil, ghee, or another liquid oil.
- Nut-free Option: You can use sunflower seed flour for nut-free keto brownies. Replace the almond flour cup for cup.
- Egg-free Option: I have not tried to make these keto brownies egg-free, but a few readers had good luck using flax seed meal and water.
- Alternate Sweeteners: I highly recommend an erythritol-based sweetener, such as Swerve or Lakanto, to achieve the best texture. Other sweeteners like BochaSweet and allulose will make them more cakey and soft.

A friend gave me a bite of a brownie from a dollar store box mix. It was very good even though overcooked. This from scratch recipe is 2000% better. Hubby says I should take her my brownie. He absolutely loved them!
Carolyn says
I am so delighted to hear that!!!
Stacy says
I don’t have the grass fed gelatin. Is it necessary?
Carolyn says
Please read the blog post!
KG says
I’d love to make these, but I always use Pyure Granular Sweetener. Should it work as the sweetener in these? Thank you!
Carolyn says
Should be fine.
Debbie Walker says
Love your website and your recipes. We are blessed that you share them.
I would love to make these for a friend. But she is allergic to almond flour. Can I substitute coconut flour one for one? Or what other keto friendly flour would you recommend? Thanks so much!

Can another nut flour be substituted for the Almond Flour? My daughter has hasimotos & avoids Almonds of any sort.

Please read the blog post as I already addressed this.
