Prep Time 20 minutes
Cook Time 30 minutes
Total Time 55 minutes


  • 5 large eggs, at room temperature, yolks and whites separated
  • 12 ounces sugar free dark chocolate, chopped, (you can also use semi-sweet chocolate, milk chocolate, etc.)
  • ¾ cup butter, cut into ½-inch cubes
  • ¼ teaspoon cream of tartar
  • ¾ cup powdered sweetener, or powdered sugar. If using 70% dark chocolate, add ¼-cup to ½-cup more sweetener.
  • ¼ teaspoon salt
  • 1 tablespoon pure vanilla extract
  • cocoa powder, powdered sugar, berries, chocolate shavings, etc., for garnish, optional


  • Preheat oven to 350˚F.
  • Grease a 9-inch springform pan with some butter and line the bottom with parchment paper. Set aside.
  • Pour water in a small saucepan; water should come up about 2 inches; set it over medium heat and bring to a simmer; decrease heat to low.
  • Put a metal bowl (or a heat-proof bowl) over the saucepan; to the top bowl, add the chocolate and butter; using a rubber spatula, stir until melted and smooth. Remove from heat and let cool slightly.
  • In the meantime, in a separate large mixing bowl, beat egg yolks with an electric mixer for 5 minutes, or until thickened and bright yellow.
  • Gradually beat in the melted chocolate mixture. Set aside.
  • In a separate large bowl add the egg whites and cream of tartar.
  • Clean the beaters and beat the egg whites on medium speed until foamy.
  • Gradually add the powdered sweetener or sugar, one tablespoon at a time. Continue to beat on high after each addition until the sugar is completely combined.
  • Add in the salt and vanilla, and continue beating on high until stiff and glossy peaks form.
  • Using a spatula, fold ¼ of the egg whites mixture into the chocolate mixture.
  • Then, fold in the remaining egg whites. Fold, do not mix, until incorporated, smooth, and chocolaty.
  • Transfer the mixture to the springform cake pan.
  • Bake for 30 to 32 minutes, or until a toothpick inserted in the center of the cake comes out with moist crumbs. Start checking for doneness around the 28-minute mark.
  • Remove the cake from the oven and let it cool on a wire rack.
  • Once cooled, loosen the sides of the cake by running a knife all around the edges of the pan.
  • Remove the rim from the pan.
  • Dust the cake with cocoa powder or confectioner’s sugar.
  • Add chocolate shavings and raspberries.
  • Serve.


  • Separating Eggs: Let eggs sit at room temperature for 20 minutes before separating.
  • Chocolate: You don't have to use sugar-free dark chocolate. You can also use semi-sweet chocolate, milk chocolate, etc.
  • Sweetener: To keep the carbohydrates lower, I used powdered sweetener, but you can also use regular powdered sugar.
  • Create Steam: This flourless chocolate cake may benefit from a steamy baking environment. Try placing an ovenproof dish with hot water in the oven to generate steam while the cake bakes. It's a simple step that will enhance the cake's texture.
  • Avoid Overbaking: For the best result, consider taking the cake out of the oven slightly "early," or when a toothpick inserted into the center has a few moist crumbs on it. 
  • Enhance the Flavor: To deepen the chocolate flavor, consider blending a spoonful of espresso or cocoa powder into the melted chocolate. Some cooks even add a pinch of cayenne pepper for a unique twist.
