# 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. 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 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, 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 three-layer vanilla sponge stays impossibly moist and tender, even days later, because the technique alternates wet and dry ingredients in a way that locks in moisture.
  • White chocolate buttercream tastes like luxury but behaves like a dream, spreading smoothly without cracking or sliding off.
  • The dramatic drip is forgiving—slight imperfections look intentional and add to the celebratory chaos.
  • Gold balloons transform a beautiful cake into an Instagram moment that actually means something.
02 -
  • White chocolate is temperamental and burns easily, so melt it slowly over barely simmering water or in thirty-second bursts in the microwave, stirring between each burst until smooth.
  • The drip will set up as it cools, so if you need to redo it, you can gently rewarm the ganache and try again, but work quickly before it hardens.
  • Room temperature ingredients are not a suggestion; cold eggs, milk, and butter will refuse to combine smoothly and create a lumpy, broken batter that bakes unevenly.
  • Gold spray can drip, so always spray the balloons over a piece of parchment paper or newspaper and let them dry completely before touching them.
03 -
  • If your buttercream breaks or looks separated while mixing, warm the bowl slightly over hot water and beat again; usually it comes back together within a minute.
  • Make the cake layers the day before if you're short on time; wrapped in plastic wrap, they stay fresh in the refrigerator for up to two days, which actually makes them slightly firmer and easier to layer.
  • The white chocolate drip can be made ahead and gently reheated in the microwave just before applying; this gives you flexibility on timing and reduces stress on the day of the party.
