Step‑by‑Step Instructions for Dark Chocolate Raspberry Mousse Cake
Step 1: Preheat the Oven and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan, ensuring coverage on all surfaces to prevent sticking. Use parchment paper for added security if desired. This will create a perfect base for your decadent Dark Chocolate Raspberry Mousse Cake.
Step 2: Combine Dry Ingredients
In a mixing bowl, whisk together 1 ½ cups of all-purpose flour, 1/2 cup of unsweetened cocoa powder, 1 teaspoon of baking powder, 1 teaspoon of baking soda, and 1/2 teaspoon of salt. Blend these ingredients thoroughly until evenly mixed to ensure the leavening agents are well-distributed, which aids in the cake’s rise and maintains that lovely chocolate flavor.
Step 3: Cream Butter and Sugar
In a large mixing bowl, combine 1/2 cup of softened unsalted butter and 1 cup of granulated sugar. Using an electric mixer, beat the mixture on medium speed for about 3 to 5 minutes until it becomes light and fluffy, turning a pale color. This step is crucial for incorporating air into your batter, creating a tender cake texture.
Step 4: Add Eggs and Vanilla
Add 2 large eggs one at a time to the creamed butter and sugar mixture, mixing well after each addition. Next, stir in 2 teaspoons of pure vanilla extract until thoroughly combined. The eggs will provide richness and structure to your Dark Chocolate Raspberry Mousse Cake, while the vanilla adds a delightful aroma.
Step 5: Mix in Dry Ingredients and Buttermilk
Gradually add the dry mixture to the wet ingredients, alternating with 1/2 cup of buttermilk. Start and end with the dry ingredients, mixing just until combined after each addition. This will ensure a smooth batter without overmixing, which could result in a dense cake.
Step 6: Bake the Cake
Pour the batter into your prepared cake pan, smoothing the top with a spatula. Place it in the preheated oven and bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean. Once done, the edges will pull slightly away from the pan, leaving you with a moist and delicious foundation for your mousse.
Step 7: Cool the Cake
Allow the cake to cool in the pan for 10 minutes before carefully transferring it to a wire rack to cool completely. This cooling step is essential to prevent melting your raspberry mousse later. Once cooled, the cake should feel firm yet springy to the touch, indicating it is ready for the next layer.
Step 8: Prepare the Raspberry Mousse
For the raspberry mousse, start by pureeing 1 cup of fresh raspberries with 3 tablespoons of granulated sugar in a blender. After blending, strain the mixture through a fine sieve to remove the seeds. This silky puree will add a refreshing contrast to the rich chocolate flavor in your Dark Chocolate Raspberry Mousse Cake.
Step 9: Whip Cream and Combine
In another bowl, whip 1 cup of heavy cream with 1 teaspoon of vanilla extract until soft peaks form. Gently fold in the cooled melted dark chocolate and the raspberry puree until just combined. Be careful not to deflate the mousse too much; you want it light and airy for the perfect texture layered in your cake. Chill the mousse in the refrigerator for 30 minutes.
Step 10: Layer the Cake
Once the cake is completely cool, use a serrated knife to slice it horizontally into two equal layers. Place the bottom layer on a serving plate and spread half of the raspberry mousse evenly on top. Carefully place the second layer over the mousse; this creates a delightful filling of flavor within your Dark Chocolate Raspberry Mousse Cake.
Step 11: Finish with Mousse
Cover the top layer of the cake with the remaining raspberry mousse, smoothing it out for an elegant finish. The mousse will add an irresistible richness to each bite. Chill the assembled cake in the refrigerator for at least 1 hour to set the mousse properly, allowing the flavors to meld beautifully together.
Step 12: Make the Ganache
To create the ganache, heat 1/2 cup of heavy cream in a small saucepan until it just begins to boil. Pour the hot cream over 6 ounces of chopped dark chocolate and let it sit for a few moments. Stir until smooth and glossy. This indulgent ganache will be the cherry on top of your already stunning cake!
Step 13: Drizzle the Ganache and Serve
Once the mousse is set, drizzle the smooth ganache over the chilled cake, letting it cascade down the sides for a breathtaking effect. Slice the cake, revealing the beautiful layers of chocolate and raspberry, and serve. Your Dark Chocolate Raspberry Mousse Cake is now ready to impress at any gathering or as a special treat at home!
Make Ahead Options
The Dark Chocolate Raspberry Mousse Cake is a fantastic option for busy home cooks looking to save time without sacrificing flavor! You can bake and cool the cake up to 3 days in advance, wrapping it tightly in plastic wrap to maintain moisture and freshness. The mousse can also be prepared 24 hours ahead; simply cover it in the refrigerator to keep it airy and light. When you’re ready to serve, layer the mousse on the cake, chill for at least 1 hour to set, and finish it off with the ganache for that extra touch of indulgence. Prepping these components ahead allows you to create an impressive dessert with minimal effort on the day of your celebration!

Dark Chocolate Raspberry Mousse Cake Recipe FAQs
What type of chocolate is best for this recipe?
Absolutely! For the best flavor, I recommend using high-quality dark chocolate (70% cocoa or more) for both the mousse and ganache. The bittersweet notes enhance the richness of the cake, creating a delectable contrast with the tartness of the raspberries. If you prefer a sweeter profile, feel free to substitute with milk chocolate or a combination of both.
How long can I store the Dark Chocolate Raspberry Mousse Cake?
You can store the cake in an airtight container in the refrigerator for up to 3 days. Make sure the mousse is adequately covered to prevent it from picking up any odors from the fridge. Keeping it chilled helps maintain that light, fluffy texture of the mousse.
Can I freeze the Dark Chocolate Raspberry Mousse Cake?
Yes, you can freeze this cake! Wrap it tightly in plastic wrap, then in aluminum foil to prevent freezer burn. It will keep well for up to 2 months. When you’re ready to enjoy it, simply thaw the cake in the refrigerator for several hours or overnight to allow it to regain its texture before serving.
What should I do if my mousse doesn’t set properly?
Very! If your mousse doesn’t seem to set, it may not have chilled long enough. I recommend letting it chill in the refrigerator for an additional 30 minutes and ensuring that the heavy cream was whipped to soft peaks. If it’s still too soft, you can gently fold in a bit of additional whipped cream to lighten it and then chill again to firm it up.
Can I make this cake gluten-free?
Definitely! To make a gluten-free Dark Chocolate Raspberry Mousse Cake, simply substitute the all-purpose flour with a gluten-free all-purpose flour blend. Make sure the blend has xanthan gum or any other binding agent to help with the structure. I often use one that includes almond flour for added richness, and it works beautifully!
How can I tell if the cake is done baking?
A great way to check if the cake is done is by inserting a toothpick into the center. If it comes out clean or with just a few moist crumbs, it’s ready! Additionally, the edges should be slightly pulling away from the sides of the pan, indicating it’s perfectly baked and ready to cool.
