Ingredients

Scale
  • 1 standard 8-inch mirror glaze base cake (your favorite recipe)
  • 1 cup white chocolate, finely chopped
  • 2/3 cup sweetened condensed milk
  • 1/2 cup granulated sugar
  • 1/4 cup water
  • 1/2 cup glucose syrup or light corn syrup
  • 1 tablespoon powdered gelatin
  • 1/4 cup cold water (for blooming gelatin)
  • Gel food coloring (black, deep blue, purple, pink, white)
  • Edible silver or gold glitter dust

Instructions

  1. Prepare your cake by ensuring it is completely frozen and placed on a wire rack set over a baking sheet to catch drips.
  2. Bloom the gelatin: Sprinkle 1 tablespoon of gelatin over 1/4 cup of cold water in a small bowl and let it sit for 5 minutes.
  3. Make the syrup: In a saucepan, combine the sugar and 1/4 cup of water. Heat until the sugar dissolves. Add the glucose syrup and bring the mixture to a boil without stirring. Remove from heat when it reaches 220 degrees Fahrenheit.
  4. Combine liquids: Pour the hot syrup over the chopped white chocolate and sweetened condensed milk in a heatproof bowl. Let it sit for 2 minutes, then stir until smooth.
  5. Melt gelatin: Gently warm the bloomed gelatin (do not boil) until it is fully liquid. Stir the liquid gelatin into the chocolate mixture until fully incorporated.
  6. Strain the glaze: Pour the mixture through a fine-mesh sieve into a clean measuring cup to remove any lumps.
  7. Color the glaze: Divide the glaze into several small bowls. Leave one portion black. Color the remaining portions with deep blue, purple, and pink. Keep the main black glaze in the largest bowl.
  8. Check temperature: Allow the glazes to cool to 90-95 degrees Fahrenheit. This temperature is crucial for a successful mirror glaze cake.
  9. Pour the glaze: Pour the black glaze over the frozen cake, covering the top and sides completely. Immediately drizzle small amounts of the blue, purple, and pink glazes randomly over the black base. Use a toothpick to gently swirl the colors together once or twice to create a nebula effect.
  10. Add stars: Before the glaze sets, lightly dust the surface with edible silver or gold glitter dust to mimic stars.
  11. Chill: Allow the glaze to set for 5 minutes. Carefully transfer the cake to a serving plate and chill for at least 2 hours before slicing.

Notes

  • For the best marble effect, work quickly once you start pouring the colors onto the black base.
  • If the glaze becomes too thick while working, gently reheat it in a warm water bath until it reaches the correct pouring temperature again.
  • Use high-quality gel colors for the most intense, deep space hues.
