11 - 6 ounces white chocolate, melted and cooled
12 - 2 to 3 tablespoons heavy cream

→ 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

# Steps:

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 prepared 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 heavy cream. Beat until light and fluffy, adding additional cream as needed for desired consistency.
08 - Level cooled cakes if needed. Place first layer on serving plate and 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 evenly.
10 - Heat heavy 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 additional ganache and smooth.
12 - Spray crispy pearls or malt balls with edible gold spray or roll in gold-dusted luster powder. Let dry completely, 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 impossibly tender and stays moist for days, which means you can actually bake this the day before without stress.
  • White chocolate buttercream tastes like silk and holds up beautifully under the weight of decorations, no sad slouching.
  • The edible gold balloons look theatrical and impressive but require zero artistic skill—spray and arrange is genuinely all you do.
02 -
  • White chocolate seizes instantly if water touches it, so make sure your bowl and utensils are completely dry when melting it, and never ever let steam from a double boiler make contact with the chocolate itself.
  • The difference between a dry, dense cake and a tender, moist one comes down to not overmixing after you add the flour—mix just until you can't see flour streaks anymore and stop there.
03 -
  • Invest in a cake turntable and offset spatula; these two tools alone make decorating feel exponentially easier and your frosting looks more refined.
  • If edible gold spray frightens you, try rolling the crispy pearls in edible gold luster dust mixed with a tiny bit of clear piping gel—it's less dramatic but equally beautiful and easier to control.
