Method
 

  1. Prepare cake batter using cake layer ingredients. Bake at 350°F (175°C) for 30–35 minutes or until a toothpick comes out clean. Cool completely.
  2. Beat butter until fluffy. Add powdered sugar gradually, then heavy cream and flavoring if desired. Mix until light and spreadable.
  3. Level cake layers and spread filling evenly between each. Stack securely and chill for at least 1 hour.
  4. Bloom gelatin in cold water. Heat glucose syrup, water, and heavy cream in a saucepan until hot. Remove from heat, stir in gelatin until dissolved. Cool to 90–95°F (32–35°C).
  5. Divide glaze into bowls and add galaxy colors. Pour over chilled cake from the center outward, letting glaze drip naturally.
  6. Add galaxy effects with edible paints, luster dust, and glitter.
  7. Let glaze set for 30 minutes before serving. Refrigerate until ready to serve.
