What is the Difference Between a Flourless Cake and a Traditional Chocolate Cake?

Traditional chocolate cake is made with white baking flour and tends to be light and kind of fluffy. Flour-free chocolate cake will be more dense. Often described as a cross between a brownie, a truffle and mousse, it is a unique dessert.

Fudgy, Chocolatey Keto Cake

Prep Time

You should plan at least 2 hours of total time from starting the project to serving the dessert to guests.


  • 8 oz sugar-free dark chocolate (it can be a chocolate bar shaved or chocolate chips)

  • ¾ cup unsalted butter cut in pieces

  • ½ cup cocoa powder

  • ½ tsp salt

  • 1 tsp espresso powder

  • 6 large eggs, room temperature

  • 1 tsp sugar free vanilla extract

  • 1/3 cup powdered sweetener

  • 1/3 cup Fiberyum Tapioca Soluble Fiber Syrup

For the Chocolate Ganache


Preheat your oven to 325°F. You will make the cake either in a 9-inch springform pan or a round metal cake pan.

Line the pan with a piece of parchment paper and generously grease the sides.

The Cake

  • If you are working with a chocolate bar, you will need to cut it into small pieces. Place the chocolate (chopped pieces or chocolate chips) in a large bowl. Add butter to the chips and place the bowl on a double boiler to melt the chips (stirring constantly until it melts).

  • Separate the eggs. The egg whites should be put in a large mixing bowl with a pinch of salt. Use either a hand mixer or a standing mixer to beat the eggs until you have stiff peaks forming. Set aside.

  • In a medium mixing bowl, place the egg yolks and add the sweetener. Mix these two ingredients for 2-3 minutes.

  • Once the yolk mixture has lightened in color, pour it over the melted chocolate, whisking while you add the yolks to ensure they don’t cook.

  • Mix in the cocoa powder.

  • Next, gently fold the egg whites into the chocolate mixture. 1/2 at a time. When your cake batter is one consistent color and appears light and airy, add the vanilla extract and espresso powder.

  • Pour the batter into the pan you have prepared with parchment paper and by greasing the sides.

  • Bake the cake for 20-25 minutes. The top will appear set but will still jiggle a bit.

  • Allow the cake to cool completely prior to adding the glaze (or ganache).

The Sugar-Free Chocolate Cake Glaze

Chocolate ganache (or chocolate glaze) adds another delicious, low-carb dimension to this fudgy dessert.

  • Melt the sugar-free chocolate chips and stir in the heavy whipping cream until smooth.

  • Top the sugar-free flourless cake with the glaze.

  • Serve and top with fresh berries or sliced toasted almonds.
