Step‑by‑Step Instructions for Dark Chocolate Raspberry Mousse Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) while you prepare an 8-inch round cake pan. Lightly grease the pan with butter and dust with cocoa powder to prevent sticking. This step ensures your Dark Chocolate Raspberry Mousse Cake bakes evenly and releases effortlessly once done.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, whisk together 1.5 cups of all-purpose flour, 1 cup of unsweetened cocoa powder, 1 teaspoon of baking powder, 1 teaspoon of baking soda, and a pinch of salt. Combine well until the mixture is uniform and free from lumps. This flour blend provides a rich and fluffy base for your cake layers, setting the stage for a delightful dessert.
Step 3: Cream Butter and Sugar
In another bowl, cream together 1 cup of softened unsalted butter and 1.5 cups of granulated sugar using an electric mixer on medium speed for about 3-4 minutes. The mixture should turn light and fluffy, creating tiny air pockets. This process incorporates air into the batter, helping your cake rise perfectly and achieve a light texture.
Step 4: Incorporate Eggs and Vanilla
Gradually add 3 large eggs to the butter mixture, one at a time, beating well after each addition. Next, stir in 2 teaspoons of vanilla extract. This step enriches the flavor profile of your Dark Chocolate Raspberry Mousse Cake, making it all the more indulgent with each whisk.
Step 5: Combine Dry and Wet Ingredients
Alternate adding the dry ingredient mixture and 1 cup of buttermilk to the creamed butter mixture. Start and end with the dry ingredients, mixing on low speed until just combined. Be careful not to overmix; you want a smooth batter that’s slightly thick yet pourable. This careful mixing helps maintain the cake’s lightness.
Step 6: Bake the Cake
Pour the prepared batter into the greased cake pan, spreading it evenly with a spatula. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted in the center comes out clean. Once baked, let it cool in the pan for 10 minutes, then transfer the cake to a wire rack to cool completely, preventing sogginess.
Step 7: Prepare the Mousse
While the cake cools, make the raspberry mousse by pureeing 1.5 cups of fresh raspberries with 2 tablespoons of sugar. Strain the puree to remove the seeds, achieving a smooth consistency. In another bowl, whip 1.5 cups of heavy cream with 1 teaspoon of vanilla extract until soft peaks form. Gently fold in the melted dark chocolate (about 6 ounces) and the raspberry puree, ensuring the mixture remains airy.
Step 8: Assemble the Cake
After the cake has cooled, slice it horizontally into two even layers. Place the first layer on a serving plate and spread half of the mousse mixture evenly on top. Carefully place the second layer on top, then spread the remaining mousse over it. Chill the cake in the refrigerator for at least 1 hour to allow the mousse to set firmly.
Step 9: Make the Ganache
For the ganache, heat 1 cup of heavy cream in a small saucepan until just boiling, then pour it over 8 ounces of chopped dark chocolate in a bowl. Let it sit for 5 minutes before stirring until smooth and glossy. Once the ganache cools slightly, drizzle it over the chilled Dark Chocolate Raspberry Mousse Cake, letting it cascade down the sides for a stunning finish.
Step 10: Serve and Enjoy
Slice your chilled Dark Chocolate Raspberry Mousse Cake into wedges and serve with additional fresh raspberries or a dollop of whipped cream if desired. This indulgent dessert showcases layers of rich chocolate cake and airy mousse, making it a standout treat for any occasion.
Make Ahead Options
These Dark Chocolate Raspberry Mousse Cakes are perfect for meal prep enthusiasts! You can bake the chocolate cake up to 3 days in advance, allowing it to cool completely before wrapping it tightly in plastic wrap and refrigerating. The raspberry mousse can also be prepared up to 24 hours ahead; just store it in an airtight container in the fridge. When it’s time to assemble, slice the cooled cake layers, spread half of the mousse on the first layer, and top with the second layer and remaining mousse. For the best texture, chill the assembled cake for at least 1 hour before serving. This way, you’ll have an elegant dessert ready with minimal effort!

Dark Chocolate Raspberry Mousse Cake Recipe FAQs
What kind of raspberries should I use for this cake?
Absolutely use fresh raspberries for the best flavor and texture in the mousse! Look for bright, plump berries with no dark spots or signs of mold. You can also opt for frozen raspberries, but ensure they’re fully thawed and drained before using to avoid excess moisture that could affect the mousse.
How should I store my Dark Chocolate Raspberry Mousse Cake?
Store your cake covered in the refrigerator for up to 3 days. I recommend wrapping it tightly in plastic wrap to maintain its moisture and prevent it from absorbing any odors. If you have leftovers, place them in an airtight container to keep them fresh.
Can I freeze the Dark Chocolate Raspberry Mousse Cake?
Yes! You can freeze the cake for up to 2 months. First, slice the cake into individual portions, wrap each piece tightly in plastic wrap, and then place them in an airtight container. When you’re ready to enjoy it, simply thaw it in the fridge overnight for the best texture.
What if my mousse is too runny?
If your mousse turns out runny, it may be due to over-mixing or not enough whipped cream. To salvage it, try whipping more heavy cream until soft peaks form, and fold it into the mousse gently. This will help lighten it up and give it that fluffy texture. Alternatively, you can refrigerate it for a while longer to see if it sets up more as it cools.
Can I make this cake dairy-free or vegan?
Absolutely! For a dairy-free version, substitute unsalted butter with coconut oil or a dairy-free butter alternative, and use full-fat coconut cream instead of heavy cream. For the eggs, you can replace each egg with 1/4 cup of unsweetened applesauce or a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons of water, let sit for 5 minutes). This way, everyone can enjoy this decadent dessert!
What gluten-free options do I have?
Very easy! Simply swap the all-purpose flour with a gluten-free flour blend that has a 1:1 ratio. Many brands are available that mimic the texture of regular flour, providing delicious results without sacrificing taste. Enjoy your gluten-free indulgence!
