Low Carb Chocolate Brownies - Rich, Fudgy, and Easy
Ingredients
- Almond flour (finely ground, not almond meal)
- Unsweetened cocoa powder (Dutch-process or natural)
- Granulated erythritol or allulose (or a blend designed for baking)
- Dark chocolate chips or chopped sugar-free chocolate (at least 70% cocoa if not sugar-free)
- Unsalted butter (or refined coconut oil for dairy-free)
- Large eggs
- Vanilla extract
- Espresso powder (optional, boosts chocolate flavor)
- Baking powder
- Fine sea salt
- Walnuts or pecans (optional, for crunch)
Instructions
- Prep the pan: Heat the oven to 350°F (175°C). Line an 8-inch square pan with parchment, leaving an overhang for easy lifting. Lightly grease the sides.
- Melt the fat and chocolate: In a microwave-safe bowl, melt 1/2 cup butter (or coconut oil) with 1/2 cup sugar-free chocolate in 20–30 second bursts, stirring until smooth. Let it cool for 2–3 minutes so it doesn’t scramble the eggs.
- Whisk in the wet ingredients: Add 3 large eggs and 2 teaspoons vanilla to the melted mixture. Whisk until glossy. If using, stir in 1/2 teaspoon espresso powder.
- Mix the dry ingredients: In a separate bowl, combine 1 1/4 cups almond flour, 1/3 cup unsweetened cocoa powder, 1 teaspoon baking powder, 1/2–3/4 cup granulated erythritol or allulose (adjust to taste), and 1/2 teaspoon fine sea salt.
- Bring it together: Fold the dry mixture into the wet mixture with a spatula until just combined. The batter will be thick. Stir in 1/3 cup chocolate chips and 1/3 cup chopped nuts if using.
- Pan and smooth: Spread the batter evenly in the prepared pan. Smooth the top with an offset spatula. For extra shine, sprinkle a few extra chips on top.
- Bake: Bake 18–24 minutes. Start checking at 18 minutes. The edges should be set and a toothpick should come out with a few moist crumbs, not wet batter.
- Cool completely: Let the brownies cool in the pan on a rack for at least 45–60 minutes. This sets the structure and improves the fudgy texture.
- Slice cleanly: Lift out using the parchment and cut into 16 squares with a sharp knife. Wipe the blade between cuts for tidy edges.
What Makes This Special
These low carb chocolate brownies use almond flour and a sugar-free sweetener to create that classic brownie moment with fewer carbs. You still get the glossy top, dense crumb, and melty chocolate pockets.
The recipe is flexible, too—use butter or coconut oil, add nuts, or swirl in cream cheese if you like. Even better, the batter comes together quickly and bakes in under 25 minutes. It’s dessert that feels indulgent but supports your goals.

Storage Instructions
- Room temperature: Store in an airtight container for up to 3 days. Add a piece of parchment between layers to prevent sticking.
- Refrigerator: Keeps well for 5–7 days. The texture becomes denser and fudgier when chilled.
- Freezer: Freeze slices on a sheet pan, then transfer to a freezer bag.
They keep for up to 2 months. Thaw at room temp for 30 minutes or microwave for 10–15 seconds.
Health Benefits
- Lower in carbs and sugar: Using almond flour and a sugar-free sweetener reduces the carb load compared to traditional brownies. This can help with blood sugar management and support keto or low carb goals.
- Higher in healthy fats: Almond flour and butter provide fats that help with satiety, so a small piece feels satisfying.
- Cocoa’s antioxidants: Unsweetened cocoa is rich in flavonoids, which can support heart health.
You still get the chocolatey payoff without the added sugar.
- Gluten-free friendly: Almond flour is naturally gluten-free. Just double-check your chocolate and baking powder for gluten-free labeling if needed.
Common Mistakes to Avoid
- Overbaking: Low carb brownies dry out quickly. Pull them when the center is just set and a toothpick shows moist crumbs.
They continue to firm up as they cool.
- Using almond meal: Coarse almond meal can make a gritty texture. Use fine blanched almond flour for the best crumb.
- Skipping the cool-down: Cutting too soon leads to crumbling. Let them cool fully for clean slices and a fudgy bite.
- Wrong sweetener: Some sweeteners crystallize and leave a gritty finish.
Allulose gives a softer texture; erythritol is crisper and cooler on the tongue. Choose based on your preference or use a blend.
- Too much leavener: Extra baking powder makes brownies cakey. Measure accurately to keep them dense and fudgy.
Alternatives
- Dairy-free: Swap butter for refined coconut oil and use dairy-free sugar-free chocolate.
Add a pinch more salt to balance the flavor.
- Nut-free: Try sunflower seed flour as a 1:1 swap for almond flour. Note that it can react with baking powder and turn green; it’s harmless. A splash of lemon juice can help reduce this.
- Extra fudgy: Reduce baking time by 2 minutes and use allulose as the sweetener.
You can also add 2 tablespoons of heavy cream or coconut milk to the batter.
- Mocha twist: Add 1 teaspoon espresso powder and a teaspoon of instant coffee granules for a deeper, roasty note.
- Peppermint swirl: Stir 1/2 teaspoon peppermint extract into the batter and top with crushed sugar-free peppermint pieces after baking.
- Protein boost: Replace 2 tablespoons of almond flour with unflavored or chocolate whey isolate. Don’t overbake, as protein can dry brownies out.
FAQ
Can I use coconut flour instead of almond flour?
Coconut flour is highly absorbent and can’t be swapped 1:1. If you must use it, start with 1/4 cup coconut flour in place of the almond flour and add an extra egg.
Expect a denser, more cake-like texture.
Which sweetener works best?
Allulose creates the softest, most traditional brownie texture and browns well. Erythritol is fine if you don’t mind a slight cooling effect and a crisper top. A 50/50 blend of allulose and erythritol often hits the sweet spot for taste and structure.
How do I get a shiny, crackly top?
Whisk the eggs thoroughly with the melted butter and chocolate to incorporate a little air and dissolve the sweetener as much as possible.
Using some melted chocolate (not just cocoa) also helps form that glossy, crackly crust.
Are these keto-friendly?
Yes, if you use a zero- or very low-carb sweetener and sugar-free chocolate. Net carbs will vary based on your ingredients and serving size, so check your labels and calculate accordingly.
Can I double the recipe?
Yes. Bake in a 9×13-inch pan and increase the time to about 22–28 minutes.
Start checking at 22 minutes and look for the same doneness cues: set edges and moist crumbs on the tester.
What if my brownies taste gritty?
That usually comes from undissolved erythritol or coarse almond meal. Try a finer sweetener, switch to allulose, or let the batter rest for 5 minutes before baking to hydrate the dry ingredients.
How can I make them more chocolatey?
Use Dutch-process cocoa for a deeper flavor, stir in extra chopped dark chocolate, and add a pinch of espresso powder. A tiny bit of salt on top also sharpens the chocolate taste.
Do I need xanthan gum?
Not for this recipe.
Almond flour and eggs provide enough structure. If you prefer a slightly chewier texture, you can add a 1/8 teaspoon, but it’s optional.
In Conclusion
Low Carb Chocolate Brownies can be rich, satisfying, and simple to make. With almond flour, the right sweetener, and a few smart techniques, you’ll get a pan of fudgy squares that feel like a treat, not a compromise.
Keep a stash in the fridge or freezer for a quick dessert or afternoon pick-me-up. Once you try this version, it may become your go-to brownie—low carb or not.
