    This keto flourless chocolate cake is pure chocolate heaven. It is super rich and decadent, yet really easy to make. This is truthfully the best keto chocolate cake I have ever made!

    I get a lot of people commenting that they are not fond of almond flour. If that describes you, this is the perfect recipe! It has no flour, not even almond flour. I adapted this recipe from the King Arthur Flourless Chocolate Cake Recipe.

    How to make keto flourless chocolate cake

    prepared cake pan
    1. Make the cake: Prepare a round cake pan by spraying with cooking spray and lining the bottom with parchment paper.

    1. Melt butter and sugar free chocolate chips together in a medium sized microwave safe bowl.

    1. Make the ganache: Heat heavy cream in a microwave safe bowl until steaming. Pour in sugar free chocolate chips and stir until melted. Spread the ganache over the cake.

    1. Serve warm, if desired, or refrigerate for 20 minutes to set the ganache.

    Ingredients

    Cake
    • 1 cup Semi-sweet Sugar free Chocolate Chips
    • ½ cup unsalted butter
    • ¾ cup sugar free granulated sweetener (see my favorite on Amazon)
    • ¼ teaspoon salt
    • 1 teaspoon vanilla extract
    • 3 large eggs beaten
    • ½ cup dutch process cocoa powder
    Ganache
    • ½ cup Semi-sweet Sugar free Chocolate Chips
    • ¼ cup heavy cream

    Equipment

    • 8 inch round cake pan

    Method

    1. Preheat the oven to 375F. Spray an 8 inch round cake pan with cooking spray and line the bottom with parchment paper.
    2. For the cake, combine the chocolate chips and butter in a medium sized microwave safe bowl. Microwave on high for 1 minute. Stir together until the chocolate is fully melted. You may need to heat for 10 more seconds.
    3. Stir in the sweetener, salt, vanilla extract, and eggs. Finally, stir in the cocoa powder. Scoop the batter into the cake pan and spread in an even layer.
    4. Bake in the preheated oven for 20-25 minutes, or until a toothpick has just a few crumbs. Let cool in the pan for 10 minutes.
    5. For the ganache, heat the cream in a small microwave safe bowl for 1 minutes. Remove from the microwave and immediately stir in the chocolate chips. Stir until the chocolate is completely melted.
    6. Invert the cake onto a plate and remove the parchment paper. Spread the ganache over top. Serve warm (the best way in my opinion) or allow the ganache to setup in the refrigerator for 20 minutes.

    Notes

    Storage: This cake can be stored in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. If you store it in the refrigerator, let it sit at room temperature for at least 30 minutes before serving.

        There is no cream cheese in this recipe. It's just a cake.

      What can I substitute for the eggs? Unable to have dairy. I use plant based butter.

      Absolutely amaze-bomb! I’m allergic to nuts, so recipes with almond flour are no-go for me. When I found your recipe, I was excited. My daughter and I enjoyed it! It was done before dinner, so we had dessert first! Sheer decadence.
