Step‑by‑Step Instructions for Dark Chocolate Raspberry Mousse Cake
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) while you prepare an 8-inch round cake pan. Grease the sides and dust with flour, ensuring an even coat to prevent sticking. You want the pan to be ready for the luscious Dark Chocolate Raspberry Mousse Cake batter you’ll soon create.
Step 2: Whisk Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt. This mixture is crucial for the cake’s structure and flavor, so be sure to blend them well until evenly combined, resulting in a rich chocolate base with a light texture.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat the softened unsalted butter and granulated sugar together until light and fluffy, about 3 to 5 minutes. The texture should be pale and airy. Add eggs one at a time, fully incorporating each before moving to the next, then stir in the pure vanilla extract for an aromatic touch.
Step 4: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk, and mix until just combined. This method helps maintain the cake’s lightness. Look for a smooth batter that is slightly thick and glossy—perfect for your decadent Dark Chocolate Raspberry Mousse Cake!
Step 5: Bake the Cake
Pour the batter into the prepared cake pan and spread it evenly. Bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean. The cake should spring back slightly when touched. Once done, let it cool in the pan for 10 minutes before turning it out onto a wire rack.
Step 6: Make the Raspberry Mousse
While the cake cools, prepare the raspberry mousse. Puree fresh raspberries with sugar, then strain the mixture to remove the seeds. In another bowl, whip the heavy cream until stiff peaks form and gently fold in the melted dark chocolate. Finally, add the raspberry puree, and chill the mousse for 30 minutes to set.
Step 7: Assemble the Cake
Once the cake has cooled completely, slice it in half horizontally using a serrated knife. Place one layer on a serving platter and spread half of the raspberry mousse over it. Add the second cake layer on top and then spread the remaining mousse evenly over the top. Chill the assembled Dark Chocolate Raspberry Mousse Cake for at least 1 hour.
Step 8: Prepare the Ganache
To create a silky ganache, heat heavy cream in a small saucepan until just boiling, then pour it over chopped dark chocolate in a separate bowl. Stir until smooth and glossy. Allow it to cool slightly before drizzling over the chilled cake, creating a stunning finish that will enhance every delightful slice.

How to Store and Freeze Dark Chocolate Raspberry Mousse Cake
Fridge: Store the cake in an airtight container in the refrigerator for up to 3 days. This helps maintain its rich flavor and fluffy texture.
Freezer: Wrap slices tightly in plastic wrap, then place in an airtight freezer bag. The cake can be frozen for up to 2 months without losing flavor.
Thawing: To enjoy a frozen slice, thaw in the refrigerator overnight before serving, ensuring the mousse remains delightful and creamy.
Reheating: If desired, you can briefly warm individual slices in the microwave for about 10-15 seconds. Be careful, as you don’t want to melt the mousse!

Dark Chocolate Raspberry Mousse Cake Recipe FAQs
What type of raspberries should I use for the mousse?
Absolutely! Fresh raspberries are ideal for this mousse due to their natural sweetness and tartness. Look for firm berries that are vibrant in color, avoiding any with dark spots or signs of over-ripeness. However, if fresh raspberries aren’t available, feel free to use frozen ones—just thaw and drain excess moisture before pureeing.
How do I store the Dark Chocolate Raspberry Mousse Cake?
Very simply! Store the cake in an airtight container in the refrigerator for up to 3 days. This helps preserve the delightful flavors and texture of the mousse. If you plan to keep it longer, consider freezing individual slices.
Can I freeze the Dark Chocolate Raspberry Mousse Cake?
Absolutely! To freeze, first wrap slices tightly in plastic wrap, ensuring no air can get in, then place them in an airtight freezer bag. The cake can be stored this way for up to 2 months. For the best result, thaw the slices in the refrigerator overnight before enjoying.
What should I do if my ganache doesn’t set?
If your ganache remains too runny, it may need more time to cool and thicken. Allow it to sit at room temperature for 15-30 minutes, and if it’s still not thick enough, you can gently reheat the ganache over low heat until warm, then let it cool again. Alternatively, adding a bit more chopped chocolate can help thicken the ganache effectively!
Are there any dietary considerations for the Dark Chocolate Raspberry Mousse Cake?
Yes, this dessert can be tailored to accommodate various dietary needs. You can substitute all-purpose flour with a 1:1 gluten-free flour blend to make it gluten-free. Additionally, check that your dark chocolate is dairy-free if you’re making this cake for someone with lactose intolerance. Always ensure to use ingredients that suit the dietary requirements of your guests.
Can I use different fruits instead of raspberries?
Very much so! This cake is highly customizable. You can substitute raspberries with strawberries, blueberries, or even tropical fruits like mango for a unique twist! If using other fruits, keep in mind that the sweetness and acidity levels may change, so adjusting sugar in the mousse might be necessary for optimal flavor.
