# How-To 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 entire cake with a thin crumb coat. Chill for 30 minutes.
09 - Apply a final thick coat of buttercream, smoothing sides and top for an even surface.
10 - Heat heavy cream until just simmering, then pour over finely chopped white chocolate. Let sit for 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, 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. 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 moist for days because of the careful ratio of butter and milk—I learned this by accident when I over-greased a pan and somehow nailed the texture.
  • White chocolate buttercream is forgiving; it hides imperfections and tastes like luxury without requiring a pastry degree.
  • Those gold balloon decorations transform a beautiful cake into a showstopper moment your guests will talk about.
02 -
  • Room temperature ingredients are not optional—cold eggs and butter will refuse to incorporate properly and you'll end up with a dense, gummy cake instead of the tender crumb this recipe promises.
  • The white chocolate ganache must cool to room temperature before you drip it, or it will run off the sides like water instead of cascading in those gorgeous, controlled streaks.
03 -
  • If your buttercream looks curdled or broken after adding white chocolate, warm it slightly (place the bowl over barely simmering water for 10 seconds) and beat it again—this usually saves it.
  • The white chocolate drip is forgiving; if your first attempt looks messy, wait for it to set, then cover the whole top with a smooth buttercream layer and try again with fresh ganache.
