Mirror glaze galaxy cake




  • Chocolate cake
  • Buttercream frosting
  • 1 Mini chocolate cupcake optional
  • 3 tablespoon gelatine powdered
  • ½ + ¾ cup Water
  • 2 cups white chocolate chips
  • ¾ cup condensed milk
  • cups sugar
  • Food colouring of your choice I have used blue, red, green and white
  • Sprinkles of your choice


  • Make sure the cake is coated with a thin layer of frosting and placed in the refrigerator for 3-4 hours
  • Place gelatine and cold water in a small bowl and allow it to absorb all the water
  • Place the white chocolate chips in a large bowl
  • Combine ¾ cup water, condensed milk and caster sugar in a heavy-bottom saucepan and bring it to a boil
  • Turn off the heat and add the gelatine. Stir well until the gelatine dissolves completely
  • Pour the hot mixture onto the chocolate chips and stir gently until smooth
  • Pour out some of the mixtures into three small bowls and let most of the mixture remain in the large bowl
  • Add the food colour of your choice. The content in the large bowl will be your base glaze and I have coloured it blue. The small bowls will be used to drizzle onto the base colour to create patterns. I have used red, green and white here
  • Let the glaze cool until it is slightly warm (about 35 degrees C). The glaze should not be runny else it will not stick onto the cake
  • Place a wire rack onto a tray (the tray is needed to catch the excess glaze). Place the cake on the rack
  • Pour half of the base colour all over the cake. Let it sit for a minute
  • Then add more base colour if needed
  • Drizzle the remaining colours to create patterns of your choice
  • If you are using a mini cupcake, pour the glaze over it and place it carefully onto the main cake
  • Add sprinkles on top and decorate the cake
  • Transfer the cake carefully onto a cake stand
  • The mirror glaze galaxy cake is ready to serve
