  • Granulated sugar, 1 cup (200 g)
  • Baking powder, 1 ½ tsp
  • Salt, ½ tsp
  • Unsalted butter, ½ cup (113 g), softened
  • Large eggs, 3, room temperature
  • Whole milk, ¾ cup (180 ml), room temperature
  • Pure vanilla extract, 1 tsp
  • Heavy cream, 1 cup (240 ml)
  • Cream cheese, 8 oz (225 g), softened
  • Powdered sugar, ¾ cup (90 g)
  • Vanilla extract, 1 tsp
  • Gelatin powder, 2 ½ tsp (about one packet)
  • Cold water, ½ cup (120 ml)
  • Granulated sugar, 1 cup (200 g)
  • Sweetened condensed milk, ⅔ cup (200 g)
  • White chocolate chips or chopped white chocolate, 8 oz (225 g)
  • Glucose syrup or light corn syrup, ⅓ cup (100 g)
  • Food coloring gels in galaxy shades (deep blues, purples, pinks, black)
  • Edible glitter or luster dust (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or line with parchment paper.
  2. In a medium bowl, whisk together flour, sugar, baking powder, and salt.
  3. In a large bowl, beat softened butter until creamy, about 2 minutes. Add eggs one at a time, beating well after each.
  4. Mix in milk and vanilla extract. Gradually add dry ingredients to wet, mixing just until combined. Divide batter evenly between pans.
  5. Bake for 25-30 minutes or until a toothpick inserted comes out clean. Let cool completely on wire racks.
  6. Whip heavy cream to stiff peaks. Beat cream cheese with powdered sugar and vanilla extract until smooth.
  7. Gently fold whipped cream into cream cheese mixture until fluffy. Refrigerate until ready to assemble.
  8. Place one cake layer on serving plate. Spread half the filling evenly over top. Add second layer and cover entire cake with remaining filling. Smooth sides and top. Chill at least 1 hour.
  9. Bloom gelatin in cold water for 5 minutes. In saucepan, combine sugar, sweetened condensed milk, and glucose syrup. Heat to 185°F (85°C), stirring gently.
  10. Remove from heat, stir in gelatin until dissolved. Pour over chopped white chocolate in heatproof bowl. Let sit 2 minutes, then whisk until smooth and melted.
  11. Cool glaze to about 90°F (32°C), stirring occasionally.
  12. Divide glaze into bowls, tint with food coloring gels. Pour different colors in spoonfuls into a large bowl without mixing.
  13. Slowly pour multicolored glaze over chilled cake, starting in center and moving outward to create galaxy swirl effect.
  14. Sprinkle edible glitter or luster dust if desired. Refrigerate 15-20 minutes to set glaze.
  15. Smooth any drips gently with warmed offset spatula if needed. Chill until serving.
  16. Slice with sharp knife dipped in hot water and wiped dry between cuts for clean edges.

Notes

Pour glaze at about 90°F (32°C) for best results. Chill cake well (ideally frozen 30 minutes) before glazing to set glaze instantly. Use powdered gelatin for easier measurement and dissolving. Whisk glaze gently to avoid air bubbles. Work quickly but calmly to prevent glaze from setting before pouring. Use a sharp knife warmed in hot water for clean slicing.
