Tools You Need

Key Ingredients & Substitutes of Sugar Free Chocolate Cake Recipe

  • Butter

    • Melted butter adds richness, moisture, and flavor.
    • If used, browned butter adds a nutty, and caramel-like flavor to baked goods. It enhances the chocolate flavor in this gluten-free, sugar-free cake and gives it a deeper, more complex taste.
    • Substitute: You can use coconut oil or ghee instead.
  • Coconut Oil

    • Coconut oil provides a plant-based fat source, adds moisture, and enhances the cake’s flavor and texture.
    • Substitute: Additional butter or another neutral oil, such as avocado oil. Surprisingly, olive oil or even extra virgin olive oil will pair well with chocolate.
  • Sugar-Free Chocolate

    • It provides the primary chocolate flavor and helps bind the ingredients.
  • Eggs

    • Eggs act as a binding agent and provide structure and richness.
    • Substitute: 1 tablespoon ground flaxseed + 3 tablespoon water, ¼ cup (4 tablespoons) Silken Tofu, or ¼ cup (4 tablespoons) Yogurt (vegan or regular) from our Egg Substitute Chart will work. 
  • Granulated Monk Fruit Sugar

    • Monk fruit sweetens this healthy chocolate cake without adding calories from sugar.
    • Substitute:
      • Allulose is natural and has a similar sweetness level and can mimic its texture and taste closely.
      • Swerve: A popular sugar replacement with a similar sweetness level.
      • Erythritol: Another sugar alcohol that is commonly used in sugar-free baking.
      • Stevia: A natural sweetener that is much sweeter than sugar, so use less.
  • Cocoa Powder

    • Unsweetened cocoa powder enhances the chocolate flavor and contributes to the sugar-free cake’s structure.
    • Substitute: Dutch-process cocoa powder for a deeper flavor.
  • Vanilla Extract

    • Vanilla extract adds depth and enhances the overall flavor.
  • Instant Espresso Powder
    • It intensifies the chocolate flavor without adding a coffee taste.
    • Substitute: Omit if desired or use brewed espresso for a similar effect.
  • Salt

    • Balances sweetness and enhances the flavors.
  • Powdered Monk Fruit Sugar (or Cocoa Powder) for Dusting

    • Provides a decorative finish and a touch of sweetness or additional chocolate flavor.
    • Substitute: Use our recipe to make other sugar-free powdered sweeteners.

How to Make Sugar Free Flourless Chocolate Cake

Prep

  1. Preheat the oven to 350°F (180°C). Butter and line a 9 inch spring form pan with parchment paper, set aside.

Make the cake batter

  1. Combine the fat and chocolate: Combine the butter, coconut oil and chopped chocolate in a microwave safe bowl and heat in 30-second intervals, stirring in between, until the chocolate is melted. Set aside to cool for 10 minutes.
  2. Add wet ingredients: Add the eggs one at a time, making sure it is fully incorporated between each addition, then add in the vanilla.
  3. Add dry ingredients: In a separate bowl, whisk in the monk fruit sugar, cocoa powder, espresso powder and salt, then whisk this into the wet ingredients until smooth.

Bake the sugar-free chocolate cake

  1. Pour the batter into the prepared tin and bake for 35-40 minutes or until the top has formed a nice crust and slightly risen.

Serve the cake

  1. Allow the cake to cool on the wire rack for about 10 minutes before releasing from the spring form pan.
  2. Dust with powdered monk fruit sugar or cocoa powder for garnish.
  3. Slice and enjoy!

A slice of Sugar Free Chocolate is served with whipped cream.

Gemma’s Pro Chef Tips

  • If you do choose to brown the butter (see the method above) be sure to remeasure the butter as you will lose volume because water in the butter evaporates during this process. You can make up the loss in volume with some additional butter or more coconut oil.
  • Coconut oil is solid at room temperature. To most easily get an accurate measurement, either use a scale to measure by weight or melt the oil to measure by volume.
  • Although we have only tested this recipe with monk fruit sweetener, you can try a different sweetener if you like. Allulose, Swerve Sweetener and coconut sugar are all options to explore if you choose. Leave your experiment results in the comments!
  • Using espresso powder in chocolate cakes helps bring out the chocolate flavor. If you don’t have any, its okay to leave it out. This cake will still be very chocolaty!
  • For the best texture, don’t overbake this cake – it is done once it has risen and the top is just set but still slightly jiggly.
  • Try serving this cake with a big scoop of our Sugar Free Ice Cream!

Make Ahead and Storage Instructions

Make-Ahead:

  • You can prepare the cake batter and refrigerate it in an airtight container for up to 24 hours. Bake per this recipe.
  • Once baked and cooled, cover it with plastic wrap or store it in an airtight container.

Storage

  • Keep the cake in the refrigerator in an airtight container for up to 4 days.
  • If you want to store it for a longer period, you can freeze it. Wrap it tightly in plastic wrap and then foil, and freeze for up to 3 months. Thaw in the refrigerator before serving.

Why Use Half Butter, Half Coconut Oil

Using half butter and half coconut oil balances flavor, texture, and health benefits, making the sugar free flourless chocolate cake both delicious and a bit more nutritious.

  • Rich Flavor and Texture: Butter adds richness and flavor to the cake, contributing to its indulgent taste and creamy texture.
  • Reduced Butter Content: By cutting down on the butter and replacing part of it with coconut oil, you reduce the overall saturated fat content.
  • Sustainable Fat Source: Coconut oil is a plant-based fat that is more sustainable compared to butter. It offers a healthier alternative while maintaining the cake’s quality.
  • Maintains Flavor and Texture: The combination of butter and coconut oil ensures that you retain the rich, fudge-like texture and flavor of the cake.
  • Nutritional Benefits: Coconut oil provides added nutritional value, such as medium-chain triglycerides (MCTs), which are thought to have health benefits.

Why Did my Flourless Chocolate Cake “Fall”?

This cake should be about an inch and a half tall and will not expand so much for the following reasons:

  • Naturally Flat: Flourless chocolate cake is dense and fudgy, so it tends to be on the flatter side and doesn’t rise significantly.
  • Minimal Rising: The cake will rise slightly during baking and form a crackly crust, but it won’t expand much.
  • Post-Baking Crust: After baking, the crust may sink a bit, which is normal and adds to the cake’s characteristic crackle.
  • Desired Result: The flatness and crackly appearance are expected and contribute to the cake’s sophisticated look and texture.
  • Sophisticated Appearance: The overall look of the cake is intentionally refined, with a slightly sunken crust enhancing its aesthetic appeal.

FAQs

Why is my flourless chocolate cake dense?

  • Flourless chocolate cake is naturally dense due to the lack of flour, which typically provides structure. The density is part of its rich, fudgy texture.

Can I make flourless chocolate cake dairy-free?

  • Yes, you can substitute the butter with dairy-free alternatives like coconut oil or vegan butter to make the cake dairy-free.

What type of sugar-free chocolate frosting goes well with this recipe?

To make a Sugar Free Fudge Frosting:

You will need:

  • 1( 14oz) can coconut cream,cold
  • 3/4 cup (3oz/85g)cocoa powder
  • 1cup (4oz/115g)confectioners swerve, or Lakanto confectioner’s Sugar

Follow the instructions:

  • Using a hand or stand mixer beat the coconut cream until very light and fluffy, 3-5 minutes. Once the cream is whipped add in the Swerve and beat to stiff peaks.
  • Once the frosting has reached stiff peaks, gradually add the cocoa powder and continue to whip until a thick rich frosting forms.

I tried this cake today and everyone loved it! I’ve been devouring it ever since it came out of the oven! Way to go, Gem Gem, once agn! :-*
Since we’ve put ourselves on healthy diets the flourless version, although fudgy, is way lighter than the usual cake.

Hi Gemma! I’m planning to make this for my husband’s birthday — he’s GF and sugar-free. Question: Does “sugar-free chocolate” mean unsweetened chocolate, or does it mean chocolate that’s been sweetened with a sugar alternative, such as coconut sugar? I think this should be clarified in the recipe, as it’s confusing. Thanks in advance for letting me know!!

Could you replace the sugar with dates? If so, how many would you suggest?

Shoot, I was planning on making this tomorrow for the first time, and I noticed an error on your recipe!! Is it 1 CUP of cocoa powder or 1/2 C.? Because you wrote 1 cup ( 4 oz.), which is a half a cup. So is it 1 C – 8 oz of cocoa powder or 1/2 C – 4 oz of cocoa powder? ( Big difference!)
Thanks
