How to Make Easy Chocolate Mousse Cake
-
Preheat Oven: Begin by setting your oven to 350°F (177°C). Don’t forget to prepare a 9-inch springform pan by greasing it lightly to prevent sticking.
-
Make Cake Batter: In a large mixing bowl, whisk together the dry ingredients—flour, sugar, cocoa powder, baking soda, baking powder, and salt. Then, blend in the wet ingredients: oil, egg, vanilla, buttermilk, and hot coffee, mixing until smooth and well combined. Pour the batter into the prepared pan.
-
Bake: Slide the cake into the preheated oven and bake for 25-30 minutes. It’s ready when a toothpick inserted into the center comes out clean. Once baked, allow the cake to cool completely in the pan on a wire rack.
-
Prepare Mousse: While the cake cools, heat 1 cup of heavy cream in a saucepan over medium heat until it simmers. Pour this hot cream over the chocolate chips in a bowl and let it sit for a few minutes to melt. Stir until smooth, then set aside to cool.
-
Whip Cream: In a separate bowl, whip the remaining heavy cream with powdered sugar and vanilla until stiff peaks form. Gently fold this whipped cream into the cooled chocolate ganache until fully combined, creating a luscious mousse.
-
Assemble Cake: Once the cake has cooled, level the top if needed. Wrap the cooled cake with an acetate collar and pour the prepared mousse over it. Refrigerate the cake for at least 6 hours, or overnight, to achieve a firm set.
-
Make Ganache Topping: For the ganache, combine the remaining chocolate chips and heavy cream in a saucepan over low heat. Stir until smooth and glossy. Allow the ganache to cool to room temperature before carefully pouring it over the set mousse layer.
-
Garnish: Before serving, consider decorating the top with fresh raspberries and chocolate-covered espresso beans for an appealing finish.
Optional: Drizzle with extra ganache for an indulgent touch.

Easy Chocolate Mousse Cake Recipe FAQs
How do I select the best ingredients for my chocolate mousse cake?
Absolutely! When choosing ingredients, ensure your chocolate is of high quality, as it greatly affects the flavor. Look for cocoa powder that is rich and aromatic with a deep color and check that your heavy whipping cream is fresh for the best volume when whipped. Use eggs that are at room temperature for a smoother batter and better emulsification, and consult your flour for any signs of being clumpy or stale.
What’s the best way to store my chocolate mousse cake?
Very important! Store the assembled cake in an airtight container or cover it with plastic wrap to prevent drying. It will stay fresh in the refrigerator for up to 5 days. If the cake is cut, you may want to use a cake dome to maintain freshness.
Can I freeze chocolate mousse cake?
Yes, you can! To freeze, wrap the entire cake tightly in plastic wrap. Follow with a layer of aluminum foil to prevent freezer burn. The cake can be frozen for up to 1 month. When ready to enjoy, thaw it overnight in the refrigerator for the best texture and flavor.
What if my mousse isn’t setting properly?
Don’t worry! If your mousse isn’t setting, it might be because the chocolate mixture was too warm when combined with the whipped cream or not enough cream was whipped to stiff peaks. Make sure to let the ganache cool to room temperature before folding in cooled whipped cream. If it still doesn’t set, consider adding a bit of gelatin (1 teaspoon dissolved in water) to help stabilize it.
Is this chocolate mousse cake suitable for people with allergies?
Absolutely! If you’re concerned about allergies, consider substituting ingredients as needed. Use gluten-free flour for a gluten-free version and replace heavy cream with coconut cream for a dairy-free option. Always check labels for allergens, particularly on chocolate products, as they can sometimes contain traces of nuts or other allergens.
Can my chocolate mousse cake be made ahead of time?
Definitely! You can prepare individual components, like the cake and mousse, up to 2 days in advance. Just ensure the cake is completely cooled before wrapping it tightly, and the mousse can be made and refrigerated. Assemble the cake on the day you plan to serve it, or simply refrigerate the layers separately to maintain freshness.
