# 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 heavy cream. Beat until light and fluffy, adding additional cream if 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 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 with spatula.
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. Arrange on top of cake in a festive cluster.
13 - Chill cake until ready to serve. Bring to room temperature before slicing.

# Expert Advice:

01 -
  • The vanilla sponge stays impossibly tender even after three layers, thanks to the milk-to-flour balance that took me two tries to perfect.
  • White chocolate buttercream tastes like silk feels, and watching people's faces when they taste it never gets old.
  • That dramatic drip isn't as scary as it looks—the timing trick I'll share makes it foolproof.
  • Gold balloon decorations turn an already beautiful cake into something Instagram-worthy without needing special skills.
02 -
  • White chocolate seizes (becomes grainy and unusable) if even a tiny bit of water gets into it, so make absolutely certain your bowl and spoon are completely dry when melting it.
  • The drip consistency is everything—too warm and it runs off the cake entirely, too cold and it won't flow; room temperature is the magic word and it's worth testing on a practice plate first.
  • Room temperature ingredients aren't optional; they truly do emulsify better and create a finer crumb that stays moist longer.
03 -
  • Invest in a kitchen scale for dividing batter evenly among pans; this guarantees three layers that bake at the same rate and stack level without drama.
  • If your white chocolate drip hardens before you finish, gently reheat it over a double boiler for 30 seconds and try again—patience with white chocolate always wins.
