Instructions

Step 1: Prepare the Bottom Layer

  1. Preheat Oven: Preheat your oven to 325°F (165°C) and grease a 9-inch springform pan.
  2. Melt the Chocolate: In a heatproof bowl, combine the butter, chopped bittersweet chocolate, and espresso powder. Melt over a double boiler or microwave in 20-second intervals, stirring until smooth.
  3. Mix Wet Ingredients: Remove from heat and whisk in the vanilla extract and egg yolks until fully incorporated.
  4. Whip Egg Whites: In a separate bowl, beat egg whites and salt until frothy. Gradually add brown sugar and whip until soft peaks form.
  5. Combine and Bake: Gently fold the whipped egg whites into the chocolate mixture in three additions. Pour into the prepared pan and bake for 15–18 minutes, or until set. Let cool completely.

Step 2: Create the Middle Layer

  1. Bloom the Cocoa: In a small bowl, whisk together the cocoa powder and hot water until smooth.
  2. Melt the Chocolate: In a separate bowl, melt the bittersweet chocolate over a double boiler or in the microwave. Allow it to cool slightly.
  3. Whip the Cream: In a chilled bowl, whip the heavy cream, sugar, and salt until soft peaks form.
  4. Assemble the Mousse: Fold the cocoa mixture into the melted chocolate.
  5. Layer and Chill: Spread the mousse evenly over the cooled bottom layer. Refrigerate for at least 30 minutes.

Step 3: Make the Top Layer

  1. Bloom the Gelatin: In a small bowl, sprinkle the gelatin over the water and let it sit for 5 minutes to bloom.
  2. Melt the White Chocolate: Melt the white chocolate in a heatproof bowl over a double boiler or microwave. Set aside.
  3. Dissolve the Gelatin: Heat the bloomed gelatin in the microwave for 10–15 seconds until fully dissolved. Stir into the melted white chocolate.
  4. Finish the Cake: Spread the white chocolate mousse evenly over the middle layer. Smooth the top with a spatula and refrigerate for at least 2 hours or overnight.

Step 4: Garnish and Serve

  1. Decorate: Dust the top with cocoa powder, garnish with shaved chocolate, or drizzle with melted chocolate for an elegant finish.
  2. Slice and Enjoy: Carefully release the cake from the springform pan. Slice with a warm knife for clean edges and serve chilled.
