# 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 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 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, 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 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 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 through center. 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 moist and tender for days, so you can bake it ahead without stress.
  • White chocolate buttercream looks like luxury but tastes like comfort, striking that perfect balance between showstopper and approachable.
  • The dramatic drip is forgiving—imperfection actually makes it more artfully modern.
  • Gold balloon decorations feel celebratory without being over the top, and you can swap them for whatever speaks to your milestone.
02 -
  • If your white chocolate buttercream looks grainy after adding the melted chocolate, the chocolate was too hot when it went in—always cool it completely before incorporating, or it'll seize and separate.
  • The drip is forgiving only if your ganache reaches room temperature; warm ganache slides off immediately, while cold ganache cracks, so patience during cooling is everything.
03 -
  • Bake your cakes a day ahead, wrap them uncut and undecorated, and refrigerate overnight—they slice cleaner and taste even more tender the next day, plus it removes the stress of decorating on the day of the celebration.
  • If edible gold spray feels intimidating, use edible gold luster dust mixed with a tiny bit of clear alcohol or vodka to paint the balloons by hand for more control and a warmer, more dimensional glow.
