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, beat butter and sugar until pale and fluffy, approximately 3 minutes. Add eggs one at a time, then incorporate vanilla extract.
04 - On low mixer speed, alternate adding flour mixture and milk in three additions, beginning and ending with flour. Mix until just combined.
05 - Divide batter evenly among prepared pans. Smooth tops and bake for 30 to 35 minutes until a toothpick inserted in the center emerges clean.
06 - Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely.
07 - Beat softened butter until smooth. Gradually add sifted powdered sugar, mixing thoroughly. Pour in melted white chocolate, vanilla extract, salt, and 2 tablespoons cream. Beat until light and fluffy, adding additional cream as needed for desired consistency.
08 - Level cooled cakes if necessary. Place first layer on serving plate, spread with buttercream. Repeat with remaining layers. Cover cake with thin crumb coat and chill for 30 minutes.
09 - Apply thick final coat of buttercream, smoothing sides and top surface.
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 top edge of cake, allowing it to cascade down the sides. Fill center with additional ganache and smooth.
12 - Spray crispy pearls or malt balls with edible gold spray or roll in luster powder. Allow to dry, then insert toothpicks or cake wires. Arrange on cake top in festive cluster.
13 - Chill cake until ready to serve. Bring to room temperature before slicing.

# Expert Advice:

01 -
  • The vanilla sponge stays impossibly moist for days, so you can bake it ahead without stress.
  • White chocolate buttercream tastes genuinely indulgent—nothing artificial, just pure richness.
  • The dramatic drip looks complicated but actually rewards patience over perfection, making you feel like a pastry chef.
  • Gold balloon decorations turn a beautiful cake into an unforgettable statement piece.
02 -
  • Room temperature ingredients are not a suggestion—cold butter won't cream properly, and cold eggs will curdle the mixture, setting you up for a dense, separated cake that no amount of love can fix.
  • White chocolate seizes instantly if it touches even a drop of water or gets too hot, so melt it slowly over low heat or use the double-boiler method, and always cool it before mixing it into buttercream.
  • The crumb coat (thin first layer of frosting) is what prevents cake crumbs from mixing into your final frosting—skip it and you'll have a spotty, unprofessional-looking cake.
  • Those gold balloons need to be completely dry before you insert them, or the edible gold will smudge and look dull rather than brilliant.
03 -
  • Weigh your cake batter before dividing it among the pans—this ensures three layers of identical thickness and even baking.
  • If your white chocolate drip is too thick, warm it slightly over a double boiler; if it's too thin, let it cool a bit longer, but never rush it or the consistency becomes unpredictable.
  • A turntable and an offset spatula are your best friends for smoothing frosting—even a lazy susan works—because they let you rotate the cake while keeping your hands still.
