Ingredients
For the Base Layer
- 200 g Chocolate sponge cake or crushed biscuits (like Oreo or Graham crackers) Mixed with melted butter
For the Vanilla Bean Mousse
- 500 ml Heavy cream To provide airy volume
- 250 g Mascarpone or cream cheese Adds stability and richness
- 1 tbsp Vanilla bean paste For authentic floral aroma
- 10 g Gelatin To hold shape when sliced
For the Blackberry Layer
- 300 g Fresh or frozen blackberries Pureed and strained
- 50 g Sugar To brighten flavor
- 1 tbsp Lemon juice To enhance the taste
- 10 g Gelatin For firmness
For the Dark Berry Mirror Glaze
- 100 g Glucose syrup For high-gloss shine
- 100 g Sugar Used in combination with glucose
- 75 ml Condensed milk Adds opacity and creaminess
- 100 g White chocolate Provides body for the glaze
- 50 g Blackberry puree or food coloring For deep color effect
Instructions
Phase 1: Preparing the Layers
- Bake the base in a springform pan or silicone mold, then let it cool completely.
- Bloom gelatin in cold water, whip heavy cream to soft peaks. Mix mascarpone, sugar, and vanilla bean paste, then fold in gelatin and whipped cream. Pour over the cooled base and freeze for 2 hours until firm.
- For the blackberry layer, repeat the process with the blackberry puree and pour over the frozen vanilla layer. Freeze again until solid.
Phase 2: Mastering the Mirror Glaze
- In a saucepan, bring water, sugar, and glucose syrup to a boil.
- Add bloomed gelatin and condensed milk, then pour the hot mixture over chopped white chocolate and blackberry puree.
- Use an immersion blender to smooth without creating air bubbles. Let cool to 32°C - 35°C (90°F - 95°F) before pouring over the cake.
Phase 3: The Pour and Decoration
- Place the frozen cake on a cooling rack over a tray. Pour the glaze in a continuous motion from the center, cleaning edges once it stops dripping.
- Transfer to a serving plate and decorate with fresh blackberries and mint.
Notes
Defrost in the refrigerator for at least 4 hours before serving. Use a hot, sharp knife to slice, cleaning the blade after each cut. The cake can be stored in the fridge for up to 3 days.
