Galaxy Mirror Glaze Cake

A stunning Galaxy Mirror Glaze Cake featuring a shiny, reflective glaze in swirling cosmic colors over a smooth mousse or ganache-coated cake.

Ingredients

Scale
  • 1 box chocolate cake mix (plus ingredients listed on box)
  • 2 cups heavy cream
  • 16 oz white chocolate, finely chopped
  • 14 oz sweetened condensed milk
  • 1/2 cup water (for blooming gelatin)
  • 2 1/2 tbsp powdered gelatin
  • 3/4 cup water (for glaze mixture)
  • Gel food coloring (black, blue, purple, pink, white)
  • Edible glitter or stars (optional)

Instructions

  1. Bake the chocolate cake according to the package instructions. Let cool completely and level the layers.
  2. Prepare a smooth surface for the cake by covering it in a thin layer of ganache or mousse. Freeze the cake until firm.
  3. Bloom gelatin in 1/2 cup cold water and set aside for 5-10 minutes.
  4. In a saucepan, combine sweetened condensed milk, 3/4 cup water, and sugar (if desired). Bring to a gentle simmer.
  5. Remove from heat and stir in the bloomed gelatin until dissolved.
  6. Pour the mixture over the chopped white chocolate and let sit for 5 minutes. Stir until smooth and fully melted.
  7. Use an immersion blender to remove bubbles and smooth the glaze.
  8. Divide the glaze into separate bowls and add gel food coloring to create galaxy colors.
  9. Let the glaze cool to about 90°F (32°C) for optimal pouring consistency.
  10. Place the frozen cake on a wire rack over a tray. Simultaneously pour the colored glazes over the cake in swirling motions to create the galaxy effect.
  11. Optional: Add white food coloring drops and drag with a toothpick to create stars or use edible glitter.
  12. Let the glaze drip and set for 10-15 minutes before trimming edges and transferring to a serving plate.

Notes

  • Ensure the cake is very cold before pouring the glaze for best results.
  • Use high-quality gel colors for vibrant hues that don’t bleed.
  • Strain the glaze before pouring to avoid lumps or bubbles.
  • Refrigerate the cake until ready to serve.
