Ingredients

• Sponge Cake
  4 large eggs
  120 g granulated sugar
  120 g all-purpose flour
  1/2 tsp vanilla extract
  1/4 tsp salt
• White Chocolate Mousse
  200 g white chocolate, chopped
  300 ml heavy cream, divided
  2 sheets gelatin (or 5 g powdered gelatin)
  1 tsp vanilla extract
• Mirror Glaze
  200 g white chocolate, chopped
  150 g granulated sugar
  100 ml water
  100 g sweetened condensed milk
  8 g powdered gelatin
  Food coloring (silver, pearl, or pastel tones)
• Decoration
  Edible silver leaf
  Edible glitter
  Sugar pearls or edible jewels

Instructions

1. Preheat your oven to 170°C (340°F).

Grease and line a large ring-shaped cake pan or a standard cake pan with a small round cutter in the center to create a ring shape.

2. For the sponge:

Whisk eggs and sugar in a stand mixer until pale and tripled in volume (about 8 minutes). Gently fold in sifted flour, vanilla, and salt. Pour into the pan and smooth the surface. Bake for 25–30 minutes, or until a toothpick comes out clean. Cool completely.

3. For the mousse:

Soften gelatin in cold water for 5 minutes. Melt white chocolate over a bain-marie or in the microwave. Heat 100 ml cream to just simmering, then dissolve the gelatin in it. Pour over melted chocolate, stirring until smooth. Cool to room temperature. Whip remaining cream to soft peaks and fold into the chocolate mixture with vanilla.

4. Assemble:

Slice the cooled cake horizontally into two layers. Place the bottom layer in a clean ring mold (or springform pan), spread half the mousse, add the top layer, and cover with remaining mousse. Smooth the top and freeze for 2 hours.

5. For the glaze:

Soften gelatin in cold water. Combine sugar, water, and condensed milk in a saucepan, bring just to a boil, then remove from heat. Stir in gelatin to dissolve, then pour over white chocolate. Let sit 2 minutes, then blend until smooth. Add food coloring for a jewel-like sheen. Cool glaze to 32°C (90°F).

6. Glazing:

Remove cake from freezer and unmold onto a wire rack. Pour mirror glaze evenly over the frozen cake, letting excess drip off. Decorate immediately with edible silver leaf, glitter, and sugar pearls to mimic a diamond ring's sparkle.

7. Finish:

Chill the finished cake in the refrigerator for 1 hour to set. Slice and serve.

Zusatztipps für die Zubereitung

Ensure your sponge batter is gently folded to keep the light texture. Using a silicone ring mold can help maintain clean edges and the perfect ring shape. Allow the mousse to chill well before glazing to prevent the glaze from melting. A kitchen thermometer is essential for achieving the ideal glaze temperature of 32°C to maintain its mirror finish.

Varianten und Anpassungen

For a fruity twist, add a thin layer of raspberry or passion fruit jam between the sponge and mousse layers. You can customize the glaze color using edible food colorings in silver, pearl, or soft pastels to match your theme. The recipe is vegetarian but not vegan; however, you can experiment with suitable gelatin alternatives if needed.

Serviervorschläge

This elegant dessert pairs beautifully with a chilled glass of Champagne or Moscato, enhancing the celebratory mood. Serve chilled for the best texture and flavor contrast. Garnish with additional edible jewels or sugar art on the serving plates to elevate presentation further.
