How to Make Stunning Dark Chocolate Raspberry Mousse Cake
Ingredients:
- 3 large eggs (room temperature)
- 55 g light brown sugar
- 65 g granulated sugar
- 1 tsp vanilla extract
- 65 g plain flour (all-purpose)
- 15 g cocoa powder
- 1 tsp baking powder
- ½ tsp espresso powder
- ¼ tsp salt
- 75 g Dark Chocolate 75% (melted)
- 2¼ tsp powdered agar-agar
- 45 ml fresh lemon juice
- 400 g fresh raspberries (frozen raspberries can be substituted; see note)
- 100 g granulated sugar
- 480 ml double cream (heavy cream) (cold)
- 125 g fresh raspberries
- 50 g Dark Chocolate shavings
Directions:
-
Prepare a pan and preheat the oven: Grease and line the base and sides of a 23cm (9-inch) springform pan. Preheat your oven to 180°C (350°F).
-
Whip the eggs & sugar: In a medium bowl, combine the eggs, light brown sugar, granulated sugar, and vanilla extract. Use a hand-held electric whisk to whip on medium-high speed until the mixture is light and creamy, about 4 minutes. It should leave trails when you lift out the whisk.
-
Add the dry ingredients and fold through: Sift the flour, cocoa powder, baking powder, espresso powder, and salt into the egg mixture. Mix on low speed until just a few flour streaks remain.
-
Add the melted chocolate: Fold in the melted chocolate with a rubber spatula, scraping the bottom of the bowl until everything is smooth.
-
Pour batter into the baking pan and bake: Pour the batter into the prepared springform pan. Tap the pan on the work surface to release air bubbles and smooth out the surface. Bake for 15-20 minutes until the center springs back. Allow to cool to room temperature.
-
Bloom agar-agar: In a small bowl, mix the lemon juice and powdered agar-agar. Let it sit for a few minutes to soften.
-
Blend raspberries: Blend the fresh raspberries until smooth. Strain the puree through a fine-mesh sieve into a saucepan, removing the seeds.
-
Heat and thicken raspberry puree: On medium-low heat, add granulated sugar to the raspberry puree and simmer. Add the agar-agar mixture and heat gently, stirring until dissolved. Remove from heat and let cool for about 20 minutes.
-
Whip cream and mix in raspberry puree: In another bowl, whip the cream until soft peaks form. Slowly mix in the cooled raspberry puree until combined.
-
Set in prepared pan: Pour the raspberry mousse over the chocolate sponge in the springform pan. Smooth the top and cover. Refrigerate for at least 3 hours, preferably overnight.
-
Remove the cake from the pan and decorate: Carefully release the cake from the pan. Garnish with fresh raspberries and chocolate shavings. Slice with a warm knife and serve immediately.
How to Serve Stunning Dark Chocolate Raspberry Mousse Cake
This cake is best enjoyed chilled. Serve slices with a dollop of whipped cream or a drizzle of raspberry sauce for extra flair. You can also add fresh berries on the side to enhance the presentation.
How to Store Stunning Dark Chocolate Raspberry Mousse Cake
Store any leftovers in the refrigerator. Cover the cake well to prevent it from absorbing other odors. It can last for up to 3 days in the fridge, but it’s best enjoyed fresh.
Tips to Make Stunning Dark Chocolate Raspberry Mousse Cake
- Ensure your ingredients are at room temperature for a better texture.
- Use a kitchen scale for precise measurements to achieve the best results.
- Don’t rush the cooling process; letting the cake cool completely will help the layers set properly.
Variation
You can switch the raspberries for other berries like strawberries or blackberries for a different flavor profile. You can also add a layer of whipped cream between the mousse layer and the chocolate sponge for added richness.
FAQs
-
Can I use frozen raspberries instead of fresh?
Yes, you can use frozen raspberries. Just make sure to thaw and drain them before blending. -
What is agar-agar, and is it necessary?
Agar-agar is a vegetarian gelatin substitute. It helps set the raspberry mousse. If you don’t have it, you can use traditional gelatin, but the texture may vary. -
How do I make this cake ahead of time?
You can prepare the cake and mousse a day in advance. Just keep it refrigerated until you’re ready to serve. It tastes even better the next day!
