11 - 6 ounces white chocolate, melted and cooled
12 - 2 to 3 tablespoons heavy cream
13 - 1 teaspoon vanilla extract

→ 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

# How to Make It:

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 and smooth tops. 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 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 with an offset spatula.
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 additional ganache and smooth.
12 - Spray crispy pearls or malt balls with edible gold spray or roll in luster powder. Let dry completely, then insert toothpicks or cake wires.
13 - Arrange gold balloon decorations on top of cake in a festive cluster. Chill cake until ready to serve.

# Additional Tips::

01 -
  • It looks impossibly fancy but the vanilla sponge is forgiving enough that even a wobbly hand won't ruin it.
  • White chocolate buttercream tastes like silky clouds, and people always ask if you used some secret ingredient (spoiler: patience is the only magic).
  • The gold balloon decoration turns a beautiful cake into an unforgettable moment—guests will actually take photos before eating.
02 -
  • The drip consistency is everything—too warm and it slides off the cake completely, too cold and it cracks; room temperature gives you that elegant cascading effect.
  • Level your cake layers before assembling or you'll end up with a leaning tower situation that no amount of frosting can fix gracefully.
  • White chocolate melts at a lower temperature than regular chocolate, so if you're melting it, use a gentle double boiler or microwave in 30-second bursts to avoid scorching it into grainy, bitter disappointment.
03 -
  • Use an oven thermometer to verify your oven temperature because cakes are sensitive to heat variations, and a 25-degree difference changes everything about the crumb structure.
  • The secret to silky white chocolate buttercream is beating it for a full minute after adding the white chocolate—this incorporates air and prevents a dense, heavy frosting.
  • If the buttercream breaks or looks grainy while you're mixing, don't panic; gently warm it over a double boiler for 30 seconds, then beat it back to smoothness.
