Equipment

  • Springform Pan or Silicone Mold
  • Saucepan
  • Hand Mixer or Stand Mixer
  • Spatula
  • Wire Rack

Ingredients
  

Mousse Cake Base

  • 200 g chocolate or fruit puree (flavor of choice)
  • 1 cup heavy cream cold, for whipping
  • 1/4 cup sugar adjust for sweetness
  • 2 egg yolks
  • 1 tsp gelatin (optional) helps structure in warm weather

Mirror Glaze

  • 1/2 cup water
  • 1 cup sugar
  • 2/3 cup sweetened condensed milk
  • 2 tbsp powdered gelatin bloomed in 1/4 cup water
  • 150 g white chocolate chopped
  • gel food coloring for desired design

Instructions
 

  • Prepare mousse: Whip heavy cream to soft peaks. In another bowl, combine yolks, sugar, and melted chocolate or fruit puree. Fold in cream gently. Add gelatin if using. Pour into mold and chill at least 4 hours.
  • For mirror glaze: In saucepan, combine water, sugar, and condensed milk. Heat until steaming, not boiling. Remove from heat, stir in bloomed gelatin and white chocolate until smooth.
  • Add gel colors as desired and blend gently. Cool glaze until 90–95°F (32–35°C)—warm but not hot.
  • Unmold chilled mousse cake onto a wire rack set over a pan. Pour glaze from the center, letting it flow down the sides. Use spatula only if needed for gentle swirls.
  • Let glaze set a few minutes, then transfer cake to serving plate. Decorate with edible glitter, gold leaf, or fresh berries.

Notes

Tips: Ensure mousse is smooth before glazing for the best shine. Avoid cheap chocolate for glaze. Slice with a hot knife for clean cuts. Mirror glaze can be colored in swirls for a galaxy effect.
