04 - 1 cup unsalted butter, room temperature
05 - 2 cups granulated sugar
06 - 4 large eggs, room temperature

09 - 1 cup unsalted butter, room temperature
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

# 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.
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, salt, and 2 tablespoons cream. Beat until light and fluffy, adding more cream 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.

# Top Tips:

01 -
  • The vanilla sponge stays moist for days, which means you can bake it ahead and actually enjoy the decorating part without rushing.
  • White chocolate buttercream is forgiving in a way chocolate never is—small temperature shifts won't cause it to seize or break.
  • Those gold balloon toppers are conversation starters that look like you spent hours in a pastry kitchen, but they're genuinely simple to assemble.
02 -
  • Room temperature ingredients are non-negotiable—cold eggs and milk will curdle into the batter and create a grainy cake instead of a silky one, and I learned this the hard way at 11 p.m. the night before a party.
  • White chocolate seizes instantly if it touches even a drop of water, so dry your bowls and utensils obsessively and melt it over the gentlest heat, stirring constantly until smooth.
  • The ganache drip is forgiving only if you let it cool completely—pour it warm and you'll create a puddle at the bottom instead of those gorgeous cascading lines.
03 -
  • If your buttercream is too soft or too stiff, temperature is usually the culprit—soft buttercream means your kitchen is warm or your ingredients were too warm, so chill everything for 15 minutes and re-beat.
  • The gold balloons are actually malt balls from the bulk candy section, which are cheaper and lighter than specialty cake decorations and work just as beautifully when dusted with gold.
  • A squeeze bottle gives you more control over the ganache drip than a spoon, but a spoon works perfectly fine if you're patient and let gravity do the work.
