Dark Chocolate Raspberry Mousse Cake Ingredients
For the Chocolate Cake
• All-purpose flour – Provides structure and stability to the cake; substitute with gluten-free flour for a gluten-free option.
• Unsweetened cocoa powder – Adds rich chocolate flavor; avoid Dutch-processed for a more intense cocoa taste.
• Granulated sugar – Sweetens and helps with moisture retention; brown sugar can add a caramel flavor.
• Baking powder – Helps the cake rise; ensure it’s fresh for maximum effectiveness.
• Baking soda – Additional leavening agent; use fresh for best results.
• Salt – Enhances flavors; don’t skip to balance sweetness.
• Unsalted butter (melted) – Adds moisture and richness; use coconut oil for a dairy-free version.
• Large eggs – Binds ingredients and creates a tender texture.
• Vanilla extract – Adds depth of flavor; pure vanilla preferred for the best taste.
• Buttermilk (or milk) – Contributes to a moist texture; substitute with yogurt or dairy-free milk if needed.
For the Raspberry Mousse
• Heavy cream (chilled) – Whipped for lightness in the mousse; coconut cream is a great dairy-free alternative.

• Powdered sugar – Sweetens the mousse; granulated sugar can be used if needed.
• Vanilla extract – Enhances mousse flavor; optional but recommended.
• Gelatin (or agar-agar) – Helps set the mousse; agar-agar is ideal for vegetarians.

For the Ganache
• Heavy cream – Adds richness to the ganache; use dark cream for a more intense flavor.

How to Make Dark Chocolate Raspberry Mousse Cake
-
Preheat your oven to 350°F (175°C) and fan grease an 8-inch round cake pan. This ensures even baking and prevents sticking.
-
Combine the dry ingredients: In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt until well mixed. This creates a strong base for your cake.
-
Mix the wet ingredients: In a separate bowl, whisk together melted butter, eggs, vanilla, and buttermilk. This adds richness and moisture to your cake.
-
Combine the mixtures: Gently add the wet ingredients to the dry ingredients and stir until just mixed. Be mindful not to overmix as this can lead to a dense cake.
-
Pour the batter into your prepared cake pan and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Let it cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
-
Bloom the gelatin by sprinkling it over 2 tablespoons of cold water; let sit for 5 minutes. Then, gently heat until dissolved; set aside to cool slightly.
-
Whip the chilled heavy cream with powdered sugar and vanilla in a mixing bowl until soft peaks form. This will give your mousse a light texture.
-
Fold in the mashed raspberries and the cooled melted dark chocolate into whipped cream, followed by adding the dissolved gelatin. This ensures the mousse is stable and luscious.
-
Slice the cooled chocolate cake horizontally to create two layers. Place one layer on a serving plate, creating a beautiful base for the mousse.
-
Spread half of the raspberry mousse over the bottom cake layer, then gently place the top layer on and finish with the remaining mousse.
-
Chill in the refrigerator for at least 2 hours to set the mousse thoroughly. This will create that delightful texture you’re after.

Prepare the ganache by heating heavy cream until it just simmers; then combine with chocolate and butter, stirring until smooth and glossy.

Pour the ganache evenly over the set mousse cake, letting it drizzle down the sides for that irresistible look.

Expert Tips
-
Clean Equipment: Ensure your mixing bowls and beaters are clean and dry for optimal whipping of the cream; any grease can prevent it from achieving soft peaks.
-
Avoid Overmixing: Be gentle when combining wet and dry ingredients to avoid overmixing; this keeps your Dark Chocolate Raspberry Mousse Cake light and fluffy.
-
Cool Ganache: Allow the ganache to cool slightly before pouring over the mousse to prevent it from melting the light layers beneath.
-
Quality Chocolate: Use dark chocolate with at least 70% cocoa content for the ganache and mousse to achieve a richer, more intense chocolate flavor.
-
Moisture Matters: For the best cake texture, ensure you use fresh buttermilk, as its acidity helps to tenderize and moisten the cake.

Dark Chocolate Raspberry Mousse Cake Recipe FAQs
How do I select ripe raspberries for this cake?
Absolutely! Look for raspberries that are plump, firm, and bright in color. Avoid any with dark spots or blemishes, as they may be overripe or spoiled. Fresh raspberries should also have a pleasant aroma. If you can’t find fresh ones, frozen raspberries can work well too—just ensure they’re unsweetened and thaw them completely before using.
How should I store leftovers of the Dark Chocolate Raspberry Mousse Cake?
Very! To keep your cake fresh, store any leftovers in an airtight container in the fridge for up to 3 days. It’s best enjoyed chilled, as this maintains the luscious texture of the mousse. Make sure to slice it before placing in the container to avoid squishing the layers!
Can I freeze the Dark Chocolate Raspberry Mousse Cake?
Definitely! You can freeze the sliced cake for up to 1 month. To do this, wrap each slice tightly in plastic wrap and then place them in a freezer-safe container. This helps keep the flavors intact. For the best experience, allow the slices to thaw in the fridge for several hours or overnight before enjoying.
What if my mousse is not setting properly?
Don’t worry! If your mousse isn’t setting, it could be due to the gelatin not dissolving properly or not cooling enough before being folded into the whipped cream. To troubleshoot, ensure you bloom the gelatin correctly by letting it sit in cold water for about 5 minutes. After dissolving it in warm water, allow it to cool slightly before incorporating it gently into the mixture.
Are there any dietary considerations for this cake?
Certainly! When making this Dark Chocolate Raspberry Mousse Cake, be mindful of allergies—especially to gluten or dairy. You can substitute the all-purpose flour with gluten-free flour and use coconut cream or a dairy-free alternative for the mousse. Additionally, if you’re catering to vegetarians, replace gelatin with agar-agar as a gelling agent.
What should I do if I have leftover ganache?
Great question! If you have leftover ganache, you can store it in an airtight container in the fridge for about 2 weeks. It’s wonderful as a topping for other desserts, like ice cream or brownies. To reuse, simply reheat gently in the microwave or over a double boiler until it reaches your desired consistency.
