Chocolate Sponge
1
|
Preheat the oven to 350 degrees F. Line a 9" springform pan with parchment paper.
2
|
In a small heat-proof bowl, combine the chocolate, oil, vanilla, espresso powder, and salt. Place the bowl over a small pot of simmering water, and stir frequently until the chocolate has full melted. Set aside to cool.
3
|
In a medium bowl, vigorously whisk the egg yolks and sugar until the mixture is pale in color and drizzles off the whisk like a ribbon.
4
|
Pour the cooled chocolate mixture into the egg yolk mixture and mix to combine.
5
|
In a separate bowl, add the egg whites and use an electric hand mixer to beat until stiff peaks form.
6
|
Use a rubber spatula to fold ⅓ of the egg whites into the yolk, chocolate mixture to loosen it up, then fold in the rest until fully combined.
7
|
Sift the flour and cocoa powder on top of the batter, then gently fold it in until fully combined. Be careful not to deflate those egg whites!
8
|
Pour the batter into the prepared pan. Bake the chocolate sponge for about 18-20 minutes or until a toothpick inserted comes out clean.
9
|
Allow the cake to cool completely before adding the jam. You can also place the cake in the fridge to cool down faster.
Jam Layer
1
|
Once the cake is cool, use a knife to loosen the cake from the edges of the pan. Open the springform pan, then add a cake collar and close the pan again.
2
|
Then, spread the raspberry preserves on top of the cake in an even layer. Set aside.
Raspberry Mousse
1
|
In a large bowl, add the water and sprinkle the gelatin on top in an even layer. Set aside to bloom.
2
|
In a small saucepan over low-medium heat, bring the milk to a simmer. Once simmering, remove from heat and mix in the freeze dried raspberry powder.
3
|
In a small bowl, whisk together the egg yolks and sugar. Temper the yolks by slowly pouring in half of the milk-raspberry mixture while whisking simultaneously. Then, pour everything back into the saucepan and place over low-medium heat. Stir frequently with a rubber spatula until it reaches 180 degrees F.
4
|
Once the mixture comes to temperature, pour it through a fine mesh sieve to remove the seeds over the bloomed gelatin. Whisk the mixture to combine.
5
|
Then, mix in the melted ruby chocolate. Set aside.
6
|
In a medium bowl, add the heavy cream and use an electric hand mixer to beat until soft peaks form.
7
|
Fold the whipped cream into the mousse until fully combined.
8
|
Gently spoon the mousse over the raspberry jam layer and use an offset spatula to smooth it out into an even layer.
9
|
Place the cake in the fridge to chill overnight.
Chocolate Ganache
1
|
In a small saucepan over low-medium heat, bring the heavy cream to a simmer, or about 190 degrees F.
2
|
Add the chocolate, then place the lid on top for one minute. Remove the lid, then stir with a rubber spatula until smooth.
Assemble
1
|
Remove the outside of the springform pan, then very gently pull the cake collar away from the cake.
2
|
Pour the ganache onto the cake, starting in the center and working outwards, leaving a border around the edge. Use an offset spatula to spread the ganache into an even layer and drip off the sides of the cake.
3
|
Arrange the fresh raspberries all over the cake as desired, and enjoy!

Tips & Tricks (5)
- Bloom Gelatin Properly 💧Always bloom gelatin in cold water for 5 minutes before dissolving to ensure smooth, lump-free mousse layers with perfect texture and stability.
- Temper Chocolate Correctly 🍫Melt dark chocolate over a double boiler, never exceeding 115°F, then cool slightly before folding into whipped cream to prevent seizing and achieve silky ganache.
- Whip Cream to Soft Peaks 🥄Stop whipping heavy cream at soft peaks rather than stiff peaks when folding into mousse mixtures—this prevents overbeating and ensures light, airy layers that aren't dense or grainy.
- Toast Espresso Powder First ☕Bloom espresso powder in a small amount of warm water before adding to the sponge batter to intensify chocolate flavor without adding excess moisture.
- Add Fresh Raspberries Last ❄️Layer fresh raspberries on top immediately before serving to prevent them from releasing juice into the mousse and causing structural breakdown or color bleeding.
