17 - 1 cup white chocolate crispy pearls or malt balls
18 - Edible gold spray or gold-dusted luster powder
19 - Toothpicks or thin cake wires

# How to Prepare:

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, 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.
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 more 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 and arrange on top of cake in a festive cluster.
13 - Chill cake until ready to serve. Bring to room temperature before slicing.

# Expert Suggestions:

01 -
  • The vanilla sponge is impossibly tender because room-temperature ingredients emulsify perfectly, creating a crumb so soft it practically melts on your tongue.
  • White chocolate buttercream tastes like luxury without requiring any special techniques—just patience and good timing.
  • The white chocolate drip is forgiving and photogenic, making your cake look professionally decorated even if this is your first time.
  • Gold balloon decorations transform an elegant cake into pure celebration, and they're actually just crispy pearls with a coat of edible spray.
02 -
  • White chocolate seizes if it touches even a tiny drop of water, so keep your bowl and utensils completely dry when melting it for the buttercream and drip.
  • Room temperature is everything in this recipe—cold eggs and butter won't emulsify properly and you'll end up with a dense, grainy cake instead of a tender one.
  • The white chocolate drip ganache must cool to room temperature before dripping, or it'll run off the sides like water instead of cascading in elegant trails.
  • Gold balloons should be attached just before serving because they can absorb moisture from the frosting and lose their shine if they sit too long.
03 -
  • Invest in a good offset spatula for frosting—it makes the difference between a lumpy cake and one with smooth, professional-looking sides.
  • If your buttercream looks grainy or separated, it means your white chocolate wasn't cool enough when you added it; beat in a tablespoon of cold cream to bring it back together.
  • Gold spray looks best when applied in light coats; heavy coats can make the crispy pearls soggy, so mist gently and let each coat dry before applying another.
