Chocolate raspberry mousse cake delivers a luxurious blend of flavors and textures. The chocolate cake layer is rich, tender, and slightly fudgy, providing a deep cocoa taste that melts on the tongue.The raspberry mousse adds a bright, tangy freshness that balances the chocolate, while the creamy texture feels light and airy.
Set your oven to 350°F (175°C). Grease an 8-inch round cake pan with butter or oil, then line it with parchment paper so the cake won’t stick.
Step 2: Prepare Dry Ingredients
In a medium bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. Mixing them now ensures an even distribution in the cake later. Set this bowl aside.
Step 3: Mix Wet Ingredients
In a large mixing bowl, combine the sugar, milk, vegetable oil, eggs, and vanilla extract. Whisk thoroughly until the mixture is smooth and uniform in texture.
Step 4: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, stirring gently. Mix just until everything is fully incorporated and there are no dry pockets of flour. Avoid over mixing to keep the cake tender.
Step 5: Add Boiling Water
Carefully pour in the boiling water while stirring. The batter will become thin; this is expected and will help the cake stay moist and light.
Step 6: Bake the Cake
Pour the batter into the prepared pan. Bake in the preheated oven for 20–25 minutes. To check doneness, insert a toothpick in the center—if it comes out clean, the cake is ready. Allow the cake to cool completely on a wire rack before proceeding.
Step 7: Make Raspberry Puree
In a small saucepan, combine raspberries, sugar, lemon juice, and a little water. Heat over medium heat for about 5 minutes, stirring occasionally. Once softened, strain the mixture through a fine sieve to remove the seeds. Let it cool slightly.
Step 8: Prepare Gelatin and Whipped Cream
Sprinkle gelatin over 1 tablespoon of cold water and let it sit for 5 minutes to bloom. Heat gently in the microwave for a few seconds to dissolve, and then stir it into the raspberry puree. Separately, whip the heavy cream until it forms stiff peaks, and then fold it gently into the raspberry puree to create a light, airy mousse.
Step 9: Assemble the Cake
Place the cooled chocolate cake on a serving plate. Spread the raspberry mousse evenly on top, smoothing it with a spatula. Refrigerate for at least 3 hours to allow the mousse to set.
Step 10: Make Ganache and Finish
Heat the cream until it just begins to boil, then pour it over the chocolate chips. Stir until smooth and glossy. Pour the ganache over the set raspberry mousse, spreading it evenly. Decorate with fresh raspberries. Chill for another 30 minutes before serving to let everything set perfectly.
Notes
❖ Cool the Cake Completely: Before assembling, make sure the chocolate cake layer is fully cooled to avoid melting the mousse. This helps maintain the cake’s structure and ensures a clean, neat finish.❖ Chill Time: The mousse needs time to firm up, so be sure to chill the cake for at least 2 hours before serving. This will help the layers set properly and allow the flavors to meld together.❖ Customization: Feel free to get creative with the decoration. Adding fresh berries, chocolate shavings, or a drizzle of raspberry sauce can elevate the presentation and add extra flavor.
