Is Flourless Chocolate Cake Keto?

Yes, this cake with no flour is naturally gluten-free, but is it Keto-friendly? Most flourless chocolate cake recipes use regular chocolate that’s sweetened with sugar, which means a higher carb content. 

It’s almost too good to believe that using sugar-free chocolate that’s sweetened with stevia or erythritol makes this flourless chocolate cake keto. 

 This delicious moist flourless cake is naturally gluten-free and keto-friendly.

Unsweetened Baker’s Chocolate or sugar-free stevia chocolate chops are an excellent choice for this cake recipe because there’s no after-taste. 

If you aren’t on a keto diet, you can make the classic flourless cake. You won’t need any low carb flours for this keto cake, so say goodbye to almond flour or coconut flour. 

In my honest opinion, this is the best flourless chocolate cake I’ve ever made. Top it with the sugar-free chocolate ganache and fresh berries for a heavenly result. 

Ingredients for Gluten-Free Flourless Chocolate cake 

This chocolate cake is gluten-free because most chocolate cake recipes with no flour are naturally gluten-free. 

The biggest win is that this is a recipe for a sugar-free keto flourless cake. And you can use your favorite powdered sugar. 

Sugar-Free Gluten-Free Flourless Chocolate Cake Recipe - This sugar-free flourless chocolate cake recipe is made with only FIVE INGREDIENTS! It's naturally gluten-free and sugar-free because it's made with dark chocolate, butter, eggs and sweetener of choice.

How To Make Flourless Chocolate Cake?

The instructions for this keto dessert are pretty simple.

how to make flourless chocolate cake step by step instructions
  1. Start by separating the eggs, placing the yolks and whites into different bowls.
  2. Beat the yolks with the sweetener until the mixture becomes light and fluffy. In a separate bowl, beat the egg whites until stiff peaks form.
  3. Melt the chocolate and butter using a double boiler or in the microwave. If using a double boiler, ensure the bowl doesn’t touch the boiling water, as this method helps melt the chocolate evenly without overheating.
  4. Next, quickly incorporate the yolk mixture into the melted chocolate, stirring in the cocoa powder as well.
  5. Gently fold the whipped egg whites into the chocolate mixture. Your keto flourless chocolate cake batter is now ready to be transferred into a springform pan lined with parchment paper. Tap the pan lightly on the counter to remove any air bubbles.
  6. Bake the cake in a preheated oven for 20-25 minutes, adjusting the time based on your preference for a fudgy texture. The cake will rise as it bakes but will collapse slightly as it cools.

Can I Make Paleo Flourless Cake?

It’s an incredibly versatile recipe that can be instantly turned into a flourless paleo recipe by switching only a few ingredients

Instead of butter, use 1/2 cup coconut oil and 1/4 cup coconut cream. Replace the sweetener with powdered coconut sugar.

How To Serve Flourless Chocolate Cake

This sugar-free flourless chocolate cake is delicious to enjoy as it is or dusted with cocoa powder or powdered sweetener. 

But, because I like things extra, I whip up a quick sugar-free ganache and load the cake with fresh raspberries on top. Here are all the ways you can serve it:

  • top with sugar-free chocolate ganache or vanilla frosting
  • decorate with fresh raspberries, blueberries, and mint leaves
  • serve with fresh homemade raspberry sauce
  • add a dollop of regular keto vanilla ice-cream
  • drizzle creamy peanut butter 

This cake is best served at room temperature, as it’s easier to slice and has a fudgy, silky texture.

This delicious gluten-free flourless chocolate cake recipe is naturally keto and sugar-free. Make it for any special occasion when you want a sugar-free fudgy flourless cake.

Ways to Store Flourless Chocolate Cake

How long can I keep the flourless chocolate cake? It can last for up to a week when refrigerated in an airtight container, though I doubt there will be any leftovers!

Is it freezer-friendly? Yes, you can freeze the flourless cake without toppings. Just wrap it in two layers of plastic wrap. When you’re ready to eat, thaw it overnight in the fridge. Then, bring it to room temperature before serving and add the toppings.

This delicious gluten-free flourless chocolate cake recipe is naturally keto and sugar-free. Make it for any special occasion when you want a sugar-free fudgy flourless cake.

Is it essential to use powdered sweeteners?

Yes, it’s vital for the best texture. A granulated sweetener may bring a grainy chocolate cake, and a liquid sweetener makes the sugar-free cake too liquidy. 

It’s super easy to make powdered sweetener at home if you have a coffee grinder or a food processor. 

How many carbs are in a flourless cake?

The classic version is pretty high in sugar and carbs. My keto flourless cake has only 7g net carbs per slice with the chocolate ganache included. If you prefer not to add any toppings, enjoy a less than 5g net carbs satisfying sugar-free, low carb dessert.

    I think you may have meant semi-sweet cholate chips for the ganache. No sugar ones would be terrible. I used the semi-sweet ones because I knew better. The ganache was fine.
    The cake had a great texture. I was very happy with that, however, your recipe says 1/2 – 2/3 cup powdered sweetener. Thinking I’d be doing myself a favor, I used only 1/2 cup. The cake was almost bitter tasting. Next time I’m using 2/3 cup for sure.
    Lastly, you do not need to quickly mix the egg yolks into the batter. “Pour the yolk mixture over the melted chocolate. Quickly whisk so the yolks won’t scramble.” If you let the chocolate mixture cool for about 10-15 minutes, there is no issue. -OR- you can add just a few tablespoons of the chocolate into the yolks, and stir well. Add another few tablespoons, and stir well. Add another few tablespoons and stir well. This is called tempering, and your eggs will not cook.
    I will definitely make this cake again, but will add the full 2/3 cup sugar substitute.

    I just made this and there was a puddle of, I’m assuming, butter floating on top. Is this normal? As the cake sat, the liquid was absorbed back into the cake.

    I did my best to follow the recipe exactly, but the batter seemed to seize when adding the sweetened egg yoke mixture to the melted chocolate. Tried with allulose and then with monk fruit/erythritol mix – same result with both sweeteners.

    Any ideas?? Maybe run the sweeteners through a food processor…

    Taste is GREAT…

    1. Thank you for trying the recipe and sharing your experience! It sounds like the batter might have seized due to the temperature difference between the melted chocolate and the egg yolk mixture. Try letting the chocolate cool slightly before mixing, and whisk quickly to combine. Running the sweeteners through a food processor could also help for a smoother texture!
