    Chef's note

    We have paired our keto chocolate cake with a chocolate cream frosting. If you want, skip the process of making the frosting and use the cake as it is for a simple breakfast or snack. Alternatively, top it with berries, or even make it into cupcakes. It’s perfect for celebrations, meal prepping, or just a regular treat.

    How to Make Keto Chocolate Cake: Step-by-Step Guide

    Cooking Methods

    • Baking

    Preparation Steps

    1. Gather and measure all the ingredients.
    2. Line an 8-inch round cake pan with parchment paper and grease the sides with butter or oil.

    Cooking Instructions

    Bake the sugar-free keto chocolate cake

    1. Preheat your oven to 350°F (175°C)
    2. In a large mixing bowl whisk dry ingredients, namely almond flour, coconut flour, cocoa powder, baking powder, baking soda, and salt until well combined.
    3. In another bowl, whisk all the wet ingredients, eggs, melted butter, almond milk, vanilla extract, apple cider vinegar, and erythritol until smooth.
    4. Pour the wet ingredients into the dry ingredients and mix until a smooth batter forms.
    5. Finally, pour the batter into the prepared cake pan and smooth the top with a spatula.
    6. Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
    7. Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

    Prepare the chocolate frosting

    1. In a mixing bowl, beat the cream cheese and softened butter until creamy.
    2. Add the powdered erythritol, cocoa powder, and vanilla extract. Continue to beat until smooth and fluffy.
    3. Once the cake is completely cool, spread the frosting evenly over the top and sides of the cake and enjoy.

    Chef's pro tip

    It’s tempting to keep mixing the batter until everything looks super smooth, but overmixing can knock the air out of the batter, leaving your cake dense instead of soft and fluffy. To prevent this, stir the ingredients together just until combined. Don’t worry about small lumps—they’ll smooth out as the cake bakes!

    What to Serve with Keto Chocolate Cake

    Serve a slice of this keto chocolate cake with a dollop of sugar-free whipped cream or a serving of warm keto cobbler for an indulging dessert experience.

    What Can I Prepare Ahead of Time

    • Chocolate cream cheese frosting: You can prepare the chocolate cream cheese frosting and store it in the refrigerator in an airtight container.

    Storage Instructions

    • Refrigerator: Store the leftover keto chocolate cake in an airtight container in the refrigerator for up to 5 days.
    • Freezer: Freeze unfrosted cake slices in a single layer, then transfer to a freezer bag for up to 3 months. Allow frozen cake slices to thaw at room temperature before serving.
