Dark Chocolate Mousse Cake Ingredients
For the Cake
• All-Purpose Flour – Provides structure to the cake. Can substitute with a gluten-free blend if needed.
• Dutch Cocoa Powder – Offers deep chocolate flavor. Not to be confused with natural cocoa powder; essential for richness.
• Fine Espresso Powder – Enhances chocolate flavor (optional). Omit if not available.
• Baking Powder – Helps the cake rise. Ensure it is fresh for proper leavening.
• Baking Soda – Further aids in rising. Do not substitute with baking powder; they serve different purposes.
• Fine Sea Salt – Balances sweetness. Regular salt can be used in a pinch but adjust quantities.
• Granulated White Sugar – Provides sweetness and moisture. Can substitute with coconut sugar for a lower glycemic option.
• Neutral Oil (Avocado, Vegetable, Canola) – Adds moisture and richness. Coconut oil can be used if melted beforehand.
• Full-Fat Sour Cream – Enhances moisture and flavor. Greek yogurt can serve as a substitute for a lighter option.
• Whole Large Egg – Provides structure and moisture. Flax egg can be used for an eggless version.
• Pure Vanilla Extract – Adds aromatic flavor. Use high-quality vanilla for best results.
• Boiling Water – Activates cocoa and hydrates the batter. Essential for achieving moisture in the dark chocolate mousse cake.
For the Mousse
• Heavy Cream – Creates a rich, creamy texture. Can substitute with coconut cream for a dairy-free option.
• Whole Large Egg and Yolk – Provides stability to the mousse. An eggless version can be created using aquafaba or additional heavy cream.
• White Granulated Sugar – Sweetens the mousse. Same options for substitution as above.
• Dark Chocolate – Main flavor ingredient; ensures a rich chocolate finish. Select between 60-70% cocoa for the best balance of sweetness and bitterness.
For the Ganache
• Heavy Cream – Provides a smooth, pourable consistency for the topping. Follow the same guidelines for substitutions as noted earlier.
• Dark Chocolate – The star of the ganache that guarantees a luscious finish. Use the same chocolate selection as for the mousse to maintain flavor consistency.

Step‑by‑Step Instructions for Triple Dark Chocolate Mousse Cake
Step 1: Preheat and Prepare
Begin by preheating your oven to 350ºF (180ºC). While it warms up, grab a 9-inch springform pan and line the bottom with parchment paper to ensure easy removal after baking. This foundational step is key to achieving a beautifully moist cake, so don’t skip it!
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, Dutch cocoa powder, fine espresso powder, baking powder, baking soda, and fine sea salt thoroughly. This blend of dry ingredients will provide the essential structure and chocolatey depth to your dark chocolate mousse cake. Set this mixture aside once combined.
Step 3: Combine Wet Ingredients
In a separate large mixing bowl, combine the granulated white sugar, neutral oil, full-fat sour cream, large egg, and pure vanilla extract. Mix these wet ingredients vigorously until the mixture becomes smooth and creamy. This ensures that the cake batter will be rich and flavorful, holding in moisture throughout baking.
Step 4: Blend Mixtures
Gradually sift the dry ingredients into the wet mixture, then carefully pour in the boiling water. Mix until just combined; do not overmix, as this could result in a dense cake. You want a smooth, luscious batter that captures the essence of dark chocolate mousse cake.
Step 5: Bake the Cake
Pour the cake batter into your prepared springform pan, spreading it evenly. Bake in your preheated oven for 24–28 minutes, or until a toothpick inserted in the center comes out clean. Once baked, cool the cake completely on a wire rack to maintain its moist texture.
Step 6: Prepare the Mousse
To create the creamy mousse, start by whisking together the heavy cream, whole egg, egg yolk, white granulated sugar, cocoa powder, espresso powder, and a pinch of salt in a saucepan without heat. Once everything is well combined, slowly heat this mixture until it reaches 170ºF (76ºC), stirring constantly to avoid scrambling the eggs.
Step 7: Incorporate Chocolate
After removing the saucepan from the heat, whisk in chunks of dark chocolate along with a splash of vanilla extract until the mixture is entirely smooth. Allow it to cool, then place the mousse in the refrigerator until it thickens, which enhances the texture and flavor for the dark chocolate mousse cake.
Step 8: Fold in Whipped Cream
Once chilled, whip some additional cold heavy cream until soft peaks form. Gently fold this whipped cream into the chocolate mixture until fully incorporated, taking care to keep the airy texture intact. This step is essential for achieving that light and fluffy mousse that contrasts beautifully with the dense cake.
Step 9: Assemble the Cake
Return the cooled cake to the springform pan and wrap the sides with a cake collar for a neat presentation. Spread the thick chocolate mousse evenly over the top of the cake, smoothing it out with a spatula. Place the cake back in the refrigerator and chill for at least 8 hours, allowing the mousse to firm up.
Step 10: Make the Ganache
To create a glossy ganache, heat heavy cream in a saucepan until it just begins to simmer. Pour it over the chopped dark chocolate in a bowl and let it sit for a few minutes. Stir until it becomes smooth and shiny. This luscious ganache will be the perfect finishing touch for your dark chocolate mousse cake.
Step 11: Finish the Cake
Once the ganache is ready and the cake has chilled adequately, pour the ganache over the top of the mousse layer and spread it evenly with a spatula. Allow the ganache to set slightly before slicing. Serve chilled for the best melt-in-your-mouth experience, and savor the indulgence of this triple dark chocolate mousse cake!
Expert Tips for Dark Chocolate Mousse Cake
-
Cocoa Quality Matters: Use high-quality Dutch cocoa powder to intensify the chocolate flavor of your cake, enhancing the overall richness in your dark chocolate mousse cake.
-
Correct Measurements: Always measure ingredients accurately. Too much flour or sugar can lead to a dense cake. Use a kitchen scale for the best results.
-
Chill for Texture: Ensure that your mousse is chilled adequately before assembling; a firm but spreadable texture is key to achieving that perfect layer atop your cake.
-
Avoid Overmixing: When combining wet and dry ingredients, mix just until incorporated. Overmixing can develop gluten, leading to a less tender cake.
-
Whip Cream to Perfection: When whipping the cream for the mousse, stop when you reach soft peaks for a light and airy texture that complements the dense cake layer beautifully.

How to Store and Freeze Dark Chocolate Mousse Cake
Fridge: Store any leftover dark chocolate mousse cake covered in the refrigerator for up to 5 days to maintain freshness and flavor.

Thawing: To enjoy frozen slices, simply transfer them to the fridge for a few hours or overnight before serving, allowing them to thaw gradually.
Reheating: For a warm treat, you can microwave individual slices on low power for about 15-20 seconds so the mousse gets slightly soft without melting the ganache.

Dark Chocolate Mousse Cake Recipe FAQs
How do I choose the right dark chocolate for my mousse?
Absolutely! When selecting dark chocolate for your mousse, aim for chocolate with a cocoa content between 60-70%. This range offers the best balance between sweetness and bitterness, resulting in a rich, complex flavor. Look for high-quality chocolate bars that contain minimal additives for a smoother texture and deeper taste in your dark chocolate mousse cake.
How should I store my leftover dark chocolate mousse cake?
To keep your dark chocolate mousse cake fresh, store any leftover slices covered in the refrigerator, where they will remain delightful for up to 5 days. Ensure it’s well-wrapped to prevent drying out and to keep out any odors from other foods in your fridge!
Can I freeze slices of dark chocolate mousse cake?
Yes! Freezing your dark chocolate mousse cake is simple. First, slice the cake, then tightly wrap each piece in plastic wrap to prevent freezer burn. Place wrapped slices in an airtight container to keep them fresh. They can be stored in the freezer for up to 2 months. When you’re ready to enjoy, thaw the slices in the refrigerator overnight for the best result.
What if my mousse doesn’t reach the right consistency?
Very! If you find that your mousse isn’t setting properly, it may not have been chilled long enough—allow it to cool and thicken in the fridge for a bit longer until it achieves a spreadable, creamy texture. If it’s too runny, consider gently folding in more whipped cream that’s been whipped to soft peaks, as this can help stabilize the mousse layer in your dark chocolate mousse cake.
Are there any common allergens in this recipe?
Yes, this recipe contains common allergens such as gluten from all-purpose flour, dairy from sour cream and heavy cream, and egg. If you’re making the cake for someone with specific dietary restrictions, you can easily adapt it! For gluten-free options, use a gluten-free flour blend; for dairy-free alternatives, opt for coconut cream and plant-based yogurt, and use substitutes like aquafaba for eggs.
What are some ways to customize this cake?
You can personalize your dark chocolate mousse cake by adding a layer of fruit preserves, like raspberry or cherry, between the cake and mousse layers for a tangy contrast. Furthermore, experimenting with different flavor extracts, such as mint or orange, can elevate this already indulgent dessert into a unique masterpiece!
