- Granulated sugar – Sweetens the cake; reduce for less sweetness or substitute with a sugar alternative.
- Eggs – Provides moisture and structure; use flaxseed meal mixed with water as an egg replacement for a vegan option.

Step‑by‑Step Instructions for Dark Chocolate Raspberry Mousse Cake
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C) while you prepare your 8-inch round cake pan. Grease the pan generously with unsalted butter or non-stick spray and dust it with a light coating of all-purpose flour, tapping out the excess. This will ensure your cake releases easily after baking.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt until well combined. This dry mixture is the foundation of your Dark Chocolate Raspberry Mousse Cake, so ensure there are no lumps. Set it aside while you move on to the wet ingredients.
Step 3: Cream Butter and Sugar
In a separate bowl, beat the softened unsalted butter and granulated sugar with an electric mixer on medium speed for about 3-5 minutes. You want the mixture to become light and fluffy, which will help create a tender cake. Once fluffy, add the eggs one at a time, mixing thoroughly after each addition, then stir in the vanilla extract.
Step 4: Combine Wet and Dry Ingredients
Gradually add the dry ingredient mixture to the creamed butter and sugar, alternating with the buttermilk. Mix on low speed until just combined, being careful not to overmix. The batter should be smooth and slightly thick, ready to transform into a moist cake.
Step 5: Bake the Cake
Pour the cake batter into your prepared pan, spreading it evenly. Place it in the preheated oven and bake for approximately 25-30 minutes or until a toothpick inserted into the center comes out clean. The cake should spring back when lightly touched.
Step 6: Cool the Cake
Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes. Carefully invert the cake onto a wire rack, allowing it to cool completely. A fully cooled cake is crucial to ensure that the layers hold together when you add the mousse.
Step 7: Prepare the Raspberry Mousse
For the mousse, start by pureeing fresh raspberries with a bit of sugar in a blender or food processor until smooth. Strain the puree through a fine sieve to remove the seeds, leaving you with a vibrant raspberry sauce. This will add a delightful tartness to your mousse.
Step 8: Whip the Cream
In a chilled bowl, whip the heavy cream with the remaining vanilla extract until soft peaks form. Be careful not to overwhip; you want a creamy texture that will incorporate well with the chocolate.
Step 9: Fold in Chocolate and Raspberry
Gently fold in the melted dark chocolate into the whipped cream until combined. Then, add the raspberry puree and fold again, taking care not to deflate the airy mixture. This luscious mousse deserves to be as light as a cloud for your Dark Chocolate Raspberry Mousse Cake.
Step 10: Assemble the Cake
Once your cake has cooled, use a serrated knife to slice it horizontally into two even layers. Place one layer on a serving plate or cake stand, and spread a generous layer of raspberry mousse over the top. Carefully position the second layer on top and top with the remaining mousse, smoothing it out elegantly.
Step 11: Chill the Assembled Cake
Cover the assembled cake with plastic wrap or a cake dome and chill it in the refrigerator for at least 1 hour. This step allows the mousse to set properly, creating a beautifully layered cake ready to impress.
Step 12: Make the Ganache
For the ganache, heat the heavy cream in a saucepan until it just begins to boil, then pour it over the chopped dark chocolate in a bowl. Let it sit for a few minutes before stirring until smooth and glossy. Once the cake is chilled, drizzle the ganache over the top, allowing it to cascade down the sides.
Step 13: Serve and Enjoy
Slice your Dark Chocolate Raspberry Mousse Cake with a sharp serrated knife for clean layers. Serve with fresh raspberries or a dollop of whipped cream for an extra touch of elegance.

Dark Chocolate Raspberry Mousse Cake Recipe FAQs
How do I select ripe berries for this cake?
Absolutely! Look for fresh raspberries that are plump, firm, and vibrant in color. Avoid those with dark spots or mushiness, as this indicates overripeness. The best time to find sweet and juicy raspberries is during their peak season, typically in late spring to early summer.
What is the best way to store leftover cake?
Very simple! Store your Dark Chocolate Raspberry Mousse Cake in an airtight container in the refrigerator for up to 3 days. This will keep it fresh while preserving its delicious flavors and soft texture. Just make sure to cover it gently to prevent it from absorbing other odors from the fridge.
Can I freeze the Dark Chocolate Raspberry Mousse Cake?
Absolutely! To freeze, wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag or container. This method will keep them fresh for up to 2 months. When you’re ready to enjoy, simply thaw the slices in the refrigerator overnight for best results, or let them sit out at room temperature for a short while.
What if my mousse doesn’t set properly?
If your mousse doesn’t set, it might be because the cream wasn’t whipped long enough or it was too warm when folded with the chocolate. To fix this, chill the mousse in the refrigerator for an additional 30 minutes, or if it’s still too soft, you can try adding a little more whipped cream to stabilize it—a real crowd-pleaser!
Can I make this cake dairy-free?
Very much so! To adapt the Dark Chocolate Raspberry Mousse Cake to a dairy-free version, replace the unsalted butter with coconut oil or vegan butter. For the heavy cream, use coconut cream, which will whip beautifully and provide that lovely texture in the mousse. Just make sure to choose dairy-free chocolate as well.
How can I ensure my cake layers are even?
To achieve perfectly even layers, use a serrated knife for slicing, and take your time to make sure they are level. You can even use a cake leveler for a professional touch!
