Description
This Keto Chocolate Mousse Cake is a low-carb, sugar-free, and gluten-free dessert perfect for satisfying chocolate cravings without compromising health. It's a rich, decadent, and airy treat that's surprisingly simple to prepare and loved by families.
Ingredients
1 cup Almond Flour
½ cup Unsweetened Cocoa Powder
¾ cup Erythritol
1 teaspoon Baking Powder
¼ teaspoon Salt
3 Large Eggs
¼ cup Melted Unsalted Butter
1 teaspoon Vanilla Extract
2 cups Heavy Cream
½ cup Erythritol
½ cup Sugar-Free Chocolate Chips
Instructions
- Prepare the Cake Base: Preheat your oven to 350°F (175°C). Grease and line an 8-inch springform pan. In a large bowl, whisk together almond flour, cocoa powder, ¾ cup erythritol, baking powder, and salt
- Combine Wet Ingredients: In a separate bowl, beat eggs, melted butter, and vanilla extract
- Mix and Bake: Pour the wet ingredients into the dry ingredients. Mix until just combined. Spread the batter evenly into the prepared pan. Bake for 15-20 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool completely on a wire rack
- Make the Chocolate Mousse: While the cake cools, melt sugar-free chocolate chips in a double boiler or microwave. Set aside to cool slightly. In a cold bowl, whip heavy cream and ½ cup erythritol until stiff peaks form. Gently fold the slightly cooled melted chocolate into the whipped cream until fully incorporated
- Assemble the Keto Chocolate Mousse Cake: Once the cake base is completely cool, spread the chocolate mousse evenly over the cake. Smooth the top with an offset spatula
- Chill: Refrigerate your Keto Chocolate Mousse Cake for at least 4 hours, or preferably overnight, to allow the mousse to set firmly
Notes
Ensure cake base is completely cool before adding mousse to prevent melting and maintain structure.
For the mousse, use a very cold bowl and cold heavy cream to achieve stiff peaks faster.
Use high-quality unsweetened cocoa powder for the richest chocolate flavor.
Do not overmix cake batter; mixing until just combined ensures a tender crumb.
Allow ample chilling time (at least 4 hours, preferably overnight) for the mousse to set beautifully and for easy slicing.
Store covered tightly in the refrigerator for up to 5 days. For longer storage, freeze individual slices (wrapped tightly) for up to 1 month and thaw overnight in the refrigerator. Reheating is not recommended as it alters the mousse's texture.

FAQs
Is this Keto Chocolate Mousse Cake truly low-carb?

What if I don’t have a springform pan for the Keto Chocolate Mousse Cake?
