Dark Chocolate Raspberry Ingredients
For the Cake
• All-purpose flour – Provides structure to the cake; substitute with gluten-free flour for a gluten-free version.
• Unsweetened cocoa powder – Adds rich chocolate flavor; ensure it’s unsweetened for the best results.
• Baking powder – Helps the cake rise; essential for achieving lightness.
• Baking soda – Works with baking powder to provide leavening.
• Salt – Enhances flavor; don’t omit for a balanced taste.
• Unsalted butter – Softened for easy mixing; use plant-based butter for a dairy-free variant.
• Granulated sugar – Sweetens the cake perfectly.
• Eggs – Provide moisture and structure; consider using flax eggs for a vegan alternative.
• Vanilla extract – Adds depth of flavor.
• Buttermilk – Contributes moisture and richness; substitute with milk and a splash of vinegar if needed.
For the Mousse
• Fresh raspberries – Add fresh flavor and serve as garnish; other berries like strawberries can also be used.

• Dark chocolate – Melted and cooled for the mousse and ganache; milk chocolate is a sweet alternative.
• Granulated sugar (for mousse) – Sweetens the raspberry mousse effectively.
For the Ganache
• Heavy cream (for ganache) – Heats up before pouring over chocolate; this creates a smooth, glossy finish.

Step‑by‑Step Instructions for Dark Chocolate Raspberry
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it heats, take an 8-inch round cake pan and generously grease it with butter before lightly dusting it with flour. This will ensure your Dark Chocolate Raspberry Mousse Cake releases easily once baked, giving you a beautiful presentation.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt until evenly combined. This dry mixture is essential for creating the structure and rich chocolate flavor in your cake, so make sure no lumps remain before moving on to the next step.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat the softened unsalted butter and granulated sugar together using a hand mixer or stand mixer for about 3-5 minutes. You’re aiming for a light and fluffy texture that will create a lovely base for your Dark Chocolate Raspberry Mousse Cake. The mixture should look pale and airy, setting the stage for the next ingredients.
Step 4: Incorporate Eggs and Vanilla
Add the eggs one at a time to the butter-sugar mixture, mixing well after each addition to ensure a homogenous mixture. Then, stir in the vanilla extract. This step not only adds rich flavor but also incorporates moisture essential for the cake’s delicate texture, blending beautifully with the chocolate.
Step 5: Combine Wet and Dry Ingredients
Gradually incorporate the dry ingredients into the wet mixture while alternately adding buttermilk. Mix gently until just combined to keep your cake light and airy. Over-mixing can lead to a dense cake, so stop as soon as no visible flour remains, ensuring that you preserve the fluffiness.
Step 6: Bake the Cake
Pour the rich chocolate batter into the prepared cake pan, smoothing the top with a spatula. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. The cake should have a slight spring when lightly pressed. Once baked, let it cool in the pan for 10 minutes before transferring it to a wire rack.
Step 7: Prepare the Raspberry Mousse
For the luscious raspberry mousse, puree fresh raspberries with granulated sugar in a blender until smooth. Strain the mixture through a fine mesh sieve to remove the seeds, then set this vibrant puree aside. In another bowl, whip the heavy cream with vanilla until soft peaks form, creating an airy texture for your mousse.
Step 8: Fold in Chocolate and Raspberry
Carefully fold the melted dark chocolate into the whipped cream until well combined, maintaining the light and fluffy texture. Next, gently add the raspberry puree, creating a beautiful marbled effect. Chill the mousse in the refrigerator for at least 30 minutes to firm up before assembling the cake.
Step 9: Assemble the Cake
Once the cake has completely cooled, slice it horizontally in half using a serrated knife. Spread half of the raspberry mousse generously on the bottom layer, then place the top layer back on. Finish by spreading the remaining mousse on top, creating an indulgent layering of flavors in your Dark Chocolate Raspberry Mousse Cake.
Step 10: Chill the Assembled Cake
Refrigerate the assembled cake for at least one hour to allow the mousse to set properly. This chilling time will ensure a cleaner slice when serving and meld the flavors beautifully, making every bite of your dessert a delightful experience.
Step 11: Make the Ganache
To create the rich chocolate ganache, heat the heavy cream in a small saucepan over medium heat until it just begins to boil. Remove it from heat and pour it over the chopped dark chocolate in a bowl. Let it sit for a few minutes before stirring until you achieve a smooth, glossy consistency.
Step 12: Finish and Serve
Drizzle the ganache over the chilled Dark Chocolate Raspberry Mousse Cake, allowing it to cascade down the sides for a stunning effect. Serve slices garnished with fresh raspberries and a dollop of whipped cream to elevate this already luxurious dessert into a memorable treat for any occasion.

How to Store and Freeze Dark Chocolate Raspberry Mousse Cake
Room Temperature: Enjoy your cake fresh for up to 1 day at room temperature, but be sure to cover it with a cake dome or wrap it tightly to maintain moisture.

Dark Chocolate Raspberry Mousse Cake Recipe FAQs
How do I select ripe raspberries for the cake?
Absolutely! Look for raspberries that are plump, firm, and vibrant in color. They should yield slightly to gentle pressure but not be overly soft or mushy. Avoid any containers with dark spots or mold, as this indicates overripeness or spoilage.
How should I store leftover Dark Chocolate Raspberry Mousse Cake?
Very! Store leftover slices in the refrigerator, tightly wrapped in plastic wrap or in an airtight container, for up to 3 days. This will help maintain its moisture and freshness. You can also keep it at room temperature for up to 1 day, but remember to cover it to prevent drying out.
Can I freeze Dark Chocolate Raspberry Mousse Cake?
Absolutely! This indulgent dessert can be frozen for up to 2 months. Make sure to wrap it tightly in plastic wrap, then cover with aluminum foil to protect against freezer burn. When you’re ready to enjoy it, thaw in the refrigerator for several hours or overnight before serving.
What should I do if my mousse isn’t thickening properly?
No worries! If your mousse seems too thin, ensure that your heavy cream was whipped to soft peaks before folding in the melted chocolate. If it’s already combined, you can refrigerate the mousse for 30 minutes to help it set better. Also, make sure your chocolate is cooled before mixing it in to prevent it from melting the whipped cream.
Is this recipe suitable for gluten-free diets?
Yes, indeed! You can easily adapt this recipe to be gluten-free by substituting all-purpose flour with a gluten-free flour blend. Be sure to choose a blend that works well for baking to maintain the texture and flavor you want in your Dark Chocolate Raspberry Mousse Cake.
