Step‑by‑Step Instructions for Dark Chocolate Raspberry Mousse Cake
Step 1: Preheat Oven
Start by preheating your oven to 350°F (175°C). While the oven heats, prepare your 8-inch round cake pan by greasing it with unsalted butter and dusting it with flour. This will help the cake release easily once baked, ensuring a perfect start for your Dark Chocolate Raspberry Mousse Cake.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together 1 ¾ cups all-purpose flour, ¾ cup unsweetened cocoa powder, 1 ½ teaspoons baking powder, ½ teaspoon baking soda, and ½ teaspoon salt. These dry ingredients will create the structure and leavening for your cake. Ensure they’re evenly combined for a consistent bake.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat ½ cup softened unsalted butter with 1 ½ cups granulated sugar until light and fluffy, about 3-5 minutes. The mixture should be pale and airy, which adds moisture and sweetness to the cake. This step builds a lovely base for your Dark Chocolate Raspberry Mousse Cake.
Step 4: Incorporate Eggs and Vanilla
Add 3 large eggs to the butter-sugar mixture one at a time, mixing well after each addition to fully incorporate. Then, mix in 1 teaspoon of pure vanilla extract, which adds depth of flavor. The mixture should look smooth and creamy, bringing you closer to that delectable cake batter.
Step 5: Combine Ingredients
Gradually add the dry mixture to the wet ingredients, alternating with 1 cup of buttermilk. Mix just until combined—do not overmix, as this can lead to a dense cake. Your batter should be silky and slightly thick, showcasing the rich chocolate hue that will define your Dark Chocolate Raspberry Mousse Cake.
Step 6: Bake the Cake
Pour the cake batter into the prepared pan and gently spread it to even out the surface. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted in the center comes out clean. Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Step 7: Prepare Raspberry Mousse
While the cake cools, blend 1 cup of fresh raspberries with 2 tablespoons of granulated sugar until smooth. Strain the puree through a fine-mesh sieve to remove seeds. In a separate bowl, whip 1 cup of heavy cream and 1 teaspoon of vanilla extract to soft peaks, then fold in 4 ounces of melted dark chocolate and the raspberry puree. Chill the mousse for at least 30 minutes to firm up.
Step 8: Assemble the Cake
Once the cake is completely cool, use a serrated knife to slice it in half horizontally into two layers. Place the bottom layer on a serving platter, and spread half of the raspberry mousse evenly on top. Carefully position the second layer on top and smooth the remaining mousse over the cake, ensuring an even, luscious layer of mousse covers the cake.
Step 9: Make Ganache
In a small saucepan over medium heat, bring ½ cup of heavy cream to a gentle boil. Remove from heat and pour it over 6 ounces of chopped dark chocolate in a bowl. Let it sit for a minute, then whisk until smooth and glossy. This ganache will be the stunning finish for your Dark Chocolate Raspberry Mousse Cake.
Step 10: Garnish
Drizzle the glossy ganache over the chilled mousse cake, allowing it to cascade down the sides. For a beautiful finishing touch, top with fresh raspberries and, if desired, a sprinkle of cocoa powder or a few mint leaves. This decoration elevates not only the presentation but also the deliciousness of your decadent dessert.

Make Ahead Options
These Dark Chocolate Raspberry Mousse Cakes are perfect for busy home cooks looking to simplify dessert preparation! You can bake the cake up to 24 hours in advance; just be sure to cool it completely before wrapping it tightly in plastic wrap to keep it moist. The raspberry mousse can be prepared up to 3 days ahead, and stored in an airtight container in the fridge to maintain its airy texture. When ready to serve, simply layer the mousse on the cooled cake, make your ganache, and drizzle it over top just before presentation. This allows your dessert to shine, ensuring you have a stunning, delicious cake with minimal last-minute effort!

Dark Chocolate Raspberry Mousse Cake Recipe FAQs
How do I choose the best raspberries for this cake?
Absolutely! When selecting fresh raspberries, look for ones that are plump, firm, and deeply colored. Avoid any berries with mold or dark spots all over, as they indicate overripeness. If using frozen raspberries, make sure to thaw them completely and drain excess juice to prevent the mousse from becoming too watery.
How should I store my leftover Dark Chocolate Raspberry Mousse Cake?
To keep the cake fresh, store it tightly covered in the refrigerator for up to three days. Make sure to use plastic wrap or an airtight container to maintain moisture and flavor. You can also freeze individual slices wrapped in plastic wrap and then in foil for up to one month—perfect for a later indulgence on a busy day!
Can I freeze the Dark Chocolate Raspberry Mousse Cake?
Absolutely! To freeze, let your cake cool completely, then slice it into portions. Wrap each slice tightly in plastic wrap, then cover with aluminum foil. This double protection will keep freezer burn away. When you’re ready to enjoy a slice, simply thaw it in the refrigerator overnight—no need to rush!
What if my mousse isn’t setting properly?
Very! If your mousse isn’t setting as it should, here are a few troubleshooting tips: Make sure to allow the mousse to chill in the refrigerator for at least 30 minutes so it thickens properly. Additionally, if the cream wasn’t whipped to soft peaks or the chocolate was still warm when mixed in, it can prevent it from setting. If you notice this, simply fold in some extra whipped cream or place it back in the fridge for a bit longer.
Are there any allergy considerations for this recipe?
Definitely! This Dark Chocolate Raspberry Mousse Cake contains common allergens like eggs, dairy, and gluten. For those with dietary restrictions, you can easily make it gluten-free by substituting all-purpose flour with a gluten-free blend. For a dairy-free version, consider using coconut cream for the mousse and a suitable vegan butter in the cake. Always check labels of your ingredients to ensure they meet your specific dietary needs!
What are some creative serving ideas for the cake?
The more the merrier! Consider serving slices topped with an extra dollop of whipped cream or pairing them with a scoop of vanilla bean ice cream for a delightful contrast.
