Chocolate Mousse Cake Ingredients
For the Cake
- All-purpose flour – Provides structure; can substitute with gluten-free flour for a lighter option.
- Granulated sugar – Sweetens the cake, crucial for caramelization; no direct substitutes suggested.
- Unsweetened cocoa powder – Deepens chocolate flavor; using Dutch-processed cocoa can add a unique taste.
- Baking soda – Acts as a leavening agent; ensure freshness for the best rise.
- Baking powder – Works with baking soda to enhance fluffiness; always check expiration date.
- Salt – Balances sweetness; use kosher salt for better granularity.
- Vegetable oil – Keeps the cake moist; can be swapped with melted butter for a richer flavor.
- Buttermilk – Adds moisture and tenderness; substitute with milk + 1 tsp vinegar or lemon juice.
- Eggs – Provide structure; for a vegan version, use flax eggs (1 tbsp flaxseed meal + 2.5 tbsp water).
- Vanilla extract – Infuses flavor into the batter; opt for pure vanilla for the best results.
- Boiling water – Blooms the cocoa and thins the batter for optimal consistency; don’t skip this step.
For the Mousse

- Semisweet chocolate – The star of the mousse, lending depth; substitute with dark chocolate for a less sweet version.
For the Ganache

Step‑by‑Step Instructions for Chocolate Mousse Cake
Step 1: Preheat and Prepare Pans
Begin by preheating your oven to 350°F (175°C). While it warms up, grease and flour two 9-inch round cake pans. This ensures your chocolate mousse cake slides out easily after baking. Set aside the prepared pans and gather your ingredients, making sure everything is within reach for a smooth baking process.
Step 2: Mix Dry Ingredients
In a large mixing bowl, sift together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking soda, baking powder, and salt. This step aerates your dry mix, promoting a light texture in the cake. Stir the mixture gently, ensuring an even blend of ingredients, which is crucial for the success of your chocolate mousse cake.
Step 3: Combine Wet Ingredients
In a separate bowl, whisk together the vegetable oil, buttermilk, eggs, and vanilla extract until smooth and well combined. This rich liquid blend infuses moisture and flavor into your chocolate mousse cake batter. Once mixed, prepare to gradually add these wet ingredients to your dry mix, creating a velvety cake batter.
Step 4: Mix Wet and Dry Ingredients
Carefully pour your wet mixture into the dry ingredients, stirring gently until just combined. The batter will be thick; then, slowly incorporate the boiling water, which will help bloom the cocoa and create a smooth consistency. Be sure to mix thoroughly, reaching a glossy finish—this is the essence of a delectable chocolate mousse cake.
Step 5: Bake the Cake
Divide the batter evenly between the two prepared pans and spread it out using a spatula for an even layer. Place the pans in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Once baked, the cakes should spring back when lightly pressed—this ensures a moist and tender result.
Step 6: Cool the Cakes
After baking, let the cakes rest in the pans for about 10 minutes. Then, carefully transfer them to cooling racks to cool completely. This cooling process is vital, as it allows the chocolate mousse cake layers to firm up, making them easier to handle and assemble later.
Step 7: Prepare the Mousse
To make the mousse, heat ½ cup of heavy cream in a small saucepan until steaming but not boiling. Pour this hot cream over chopped semisweet chocolate in a bowl, allowing it to sit for a minute before whisking until smooth and fully melted. This silky chocolate mixture is the heart of your chocolate mousse cake.
Step 8: Whip the Cream for Mousse
In a separate bowl, whip the remaining heavy cream until it reaches soft peaks. Gently fold the whipped cream into the cooled chocolate mixture until fully combined. This step is key for the airy texture of the mousse. Once mixed, chilling the mousse in the refrigerator for at least 1 hour will help it set.
Step 9: Make the Ganache
For the ganache, heat 1 cup of heavy cream in a saucepan until it simmers. Pour this hot cream over chopped semisweet chocolate in a bowl, similar to the mousse preparation. Allow it to sit for a minute before stirring until smooth and glossy, ensuring a luxurious finish for your chocolate mousse cake.
Step 10: Assemble the Cake
Once the cakes are completely cool, place one layer on a serving platter. Spread a generous layer of mousse over the top, then gently place the second cake layer on top. Finish by covering the entire cake with the remaining mousse and pour the luxurious ganache over the top, letting it drizzle down the sides for a stunning presentation.

Chocolate Mousse Cake Recipe FAQs
How do I select the best chocolate for my cake?
Absolutely! For the best flavor, choose high-quality semisweet or dark chocolate with a cocoa percentage of at least 60%. The richness of the chocolate directly impacts the overall flavor of your chocolate mousse cake. If you prefer a sweeter taste, you can opt for high-quality milk chocolate instead, but it may yield a different richness.
Can I make this recipe gluten-free?
Very! To make a gluten-free chocolate mousse cake, simply substitute the all-purpose flour with a gluten-free flour blend. Make sure it has a good structure and is designed for baking, as this will mimic the properties of regular flour. Always check the labels to ensure all other ingredients are also gluten-free.
How should I store leftover chocolate mousse cake?
For sure! Store leftover cake in an airtight container in the refrigerator for up to 4 days. This keeps the cake fresh while preserving the delightful texture and flavor. If you want to keep it longer, you can freeze individual slices to enjoy later.
What is the best way to freeze chocolate mousse cake?
Absolutely! To freeze your chocolate mousse cake, wrap individual slices tightly in plastic wrap, then place them in a freezer-safe bag. Label the bag with the date, and your cake can be stored for up to one month. When ready to eat, thaw it in the refrigerator overnight; this method maintains the silky mousse texture nicely.
Can I use dairy alternatives for this recipe?
Yes, definitely! If you’re looking for a dairy-free option, use plant-based milk combined with a teaspoon of vinegar or lemon juice instead of buttermilk, and choose coconut cream or a dairy-free whipped cream for the mousse. Just ensure you select a dairy-free chocolate to keep the whole dessert vegan-friendly.
What if my mousse doesn’t set properly?
No problem! If your mousse doesn’t seem to set after chilling for the recommended time, it could be due to over-whipping the cream or not allowing the chocolate mixture to cool sufficiently before combining. Next time, ensure the chocolate mixture cools to room temperature before folding in the whipped cream. If you’re in a pinch, you can re-whip the mixture gently and chill it again for at least 30 minutes.
