05 - 2 cups granulated sugar

10 - 4 cups powdered sugar, sifted
11 - 6 ounces white chocolate, melted and cooled
12 - 2 to 3 tablespoons heavy cream
13 - 1 teaspoon vanilla extract
14 - Pinch of salt

→ White Chocolate Drip

15 - 6 ounces white chocolate, finely chopped
16 - ¼ cup heavy cream

→ Gold Balloons Decoration

17 - 1 cup white chocolate crispy pearls or malt balls
18 - Edible gold spray or gold-dusted luster powder
19 - Toothpicks or thin cake wires

# Directions:

01 - Preheat oven to 350°F. Grease and line three 8-inch round cake pans with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt.
03 - In a large bowl, cream butter and sugar until pale and fluffy, approximately 3 minutes. Beat in eggs one at a time, then add vanilla extract.
04 - With mixer on low speed, alternate adding flour mixture and milk, beginning and ending with flour. Mix until just combined.
05 - Divide batter evenly among pans. Smooth tops and bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean.
06 - Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely.
07 - Beat butter until smooth. Gradually add sifted powdered sugar, mixing well. Pour in melted white chocolate, vanilla extract, salt, and 2 tablespoons cream. Beat until light and fluffy, adding more cream as needed for desired consistency.
08 - Level cooled cakes if needed. Place first layer on serving plate, spread with buttercream. Repeat with remaining layers, then cover cake with a thin crumb coat. Chill for 30 minutes.
09 - Apply a final thick coat of buttercream, smoothing sides and top.
10 - Heat cream until just simmering, then pour over chopped white chocolate. Let sit 1 minute, then stir until smooth. Cool to room temperature.
11 - Using a spoon or squeeze bottle, drip white chocolate ganache around the top edge of the cake, letting it cascade down the sides. Fill center with more ganache and smooth.
12 - Spray crispy pearls or malt balls with edible gold spray, or roll in luster powder. Let dry, then insert toothpicks or cake wires. Arrange on top of cake in a festive cluster.
13 - Chill cake until ready to serve. Bring to room temperature before slicing.

# Expert Tips:

01 -
  • The vanilla sponge is genuinely tender and never dry, thanks to the milk and proper creaming technique that I learned the hard way after one too many dense attempts.
  • White chocolate buttercream feels luxurious without being overwhelming, and it actually pipes cleanly if you chill it first.
  • That dramatic drip effect looks professional enough to fool people into thinking you hired a baker, but it's honestly forgiving and fun to execute.
02 -
  • Room temperature ingredients are genuinely non-negotiable for this cake; I learned this the hard way when I tried to speed things up and ended up with a grainy, separated mess that wouldn't bake evenly.
  • The white chocolate drip only looks perfect if the ganache is completely cooled to room temperature before you apply it; warm ganache melts into the buttercream and loses that beautiful definition.
  • Sifting the powdered sugar actually matters because unsifted powdered sugar creates tiny lumps that never fully incorporate into the buttercream, leaving a grainy texture.
03 -
  • If your edible gold spray isn't giving you the coverage you want, apply a thin first coat, let it dry for thirty seconds, and do a second coat—it looks richer and more luxurious.
  • Use a turntable when frosting the cake; it makes spreading buttercream smoothly around the sides infinitely easier and actually faster than trying to frost on a stationary plate.
