Directions
- Make the Chocolate Sponge Cake: Preheat the oven to 350°F (175°C). Line a 9-inch cake pan with parchment paper and spray with non-stick oil. Whisk the eggs and granulated sugar for 3-4 minutes until tripled in volume.
- Add Dry Ingredients: Sift the flour, cocoa powder, baking powder, and salt into the egg mixture. Fold gently until just combined, being careful not to deflate the batter.
- Bake the Cake: Pour the batter into the prepared pan and bake for 13-14 minutes, until a toothpick comes out with moist crumbs. Let cool completely.
- Make the Simple Syrup: Combine the water and sugar in a small saucepan. Heat on low until the sugar dissolves. Set aside to cool.
- Make the Chocolate Mousse: Bloom the gelatin in cold water for 5-10 minutes. Heat ½ cup heavy cream to a boil, then pour over the semi-sweet chocolate. Stir until smooth. Stir in the bloomed gelatin and let cool for 15-20 minutes.
- Whip the Cream for the Mousse: Whip 1 ½ cups of chilled heavy cream until stiff peaks form. Gently fold it into the chocolate ganache in 2-3 additions.
- Make the White Chocolate Mocha Mousse: Bloom the gelatin in cold water. Heat ½ cup heavy cream to a boil and pour over white chocolate. Stir until smooth. Mix in instant coffee and bloomed gelatin, then set aside to cool.
- Whip the Cream for the Mocha Mousse: Whip 1 ½ cups chilled heavy cream until stiff peaks form. Gently fold it into the white chocolate ganache in 2-3 additions.
- Assemble the Cake: Place the chocolate cake on a serving stand. Brush with simple syrup. Wrap the cake with an acetate collar. Spread the chocolate mousse evenly over the cake. Chill for 30-45 minutes until set.
- Top with White Chocolate Mocha Mousse: Spoon the white chocolate mocha mousse over the chocolate mousse layer and spread evenly. Chill for at least 6 hours or overnight.
- Make the Chocolate Glaze: Heat the heavy cream to a boil and pour over semi-sweet chocolate. Stir in the vegetable oil and cool for 5 minutes.
- Finish the Cake: Remove the acetate collar and smooth the edges with an offset spatula. Pour the glaze over the cake and let it drip down the edges.
