# 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 more 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. Cover cake with a thin crumb coat and chill for 30 minutes.
09 - Apply a final thick coat of buttercream, smoothing sides and top evenly.
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 remaining 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 Tips:

01 -
  • The vanilla sponge stays impossibly tender for days, unlike those dense grocery store cakes that go stale by Tuesday.
  • White chocolate buttercream tastes luxurious but doesn't require any fancy equipment or temperamental techniques.
  • The dramatic drip makes your cake look professionally decorated, even if this is your first time attempting it.
  • Gold balloon decorations turn an already beautiful cake into an Instagram-worthy centerpiece that guests actually want to photograph.
02 -
  • Room temperature ingredients are absolutely critical—cold ingredients won't emulsify properly and you'll end up with a separated, grainy buttercream that's heartbreaking to fix.
  • Don't skip the crumb coat step even though it feels like an extra step; it's the difference between a professional-looking cake and one that looks homemade in a less-flattering way.
  • White chocolate can be temperamental with heat, so let your ganache cool to room temperature before pouring it or it will melt your buttercream and ruin all your careful work.
  • The gold balloons can be assembled hours ahead, which is a lifesaver if you're baking this for an actual celebration and need to manage your timing.
03 -
  • Use a serrated bread knife dipped in hot water to level your cakes—the heat helps it glide through cleanly without crumbling.
  • If your buttercream breaks or looks separated after adding the white chocolate, it's usually because something wasn't room temperature; add an ice cube and beat it, and often it comes back together.
  • Make your ganache while your buttercream is chilling so everything flows smoothly without you stressing about timing on the day of serving.
