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
- Preheat Oven:
- Preheat your oven to 170℃ (340℉). 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.
- Make Sponge Cake:
- 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 to 30 minutes, or until a toothpick comes out clean. Cool completely.
- Prepare 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.
- Assemble Cake:
- 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.
- Make 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℃ (90℉).
- Glaze Cake:
- 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 rings sparkle.
- Chill:
- Chill the finished cake in the refrigerator for 1 hour to set. Slice and serve.
