# How To Make:

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, alternately add 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 additional cream as needed for desired consistency.
08 - Level cooled cake layers 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 surface.
10 - Heat cream until just simmering, then pour over finely 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, 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 gold-dusted luster powder. Let dry completely, then insert toothpicks or cake wires. Arrange in a festive cluster on top of cake.
13 - Chill cake until ready to serve. Bring to room temperature before slicing.

# Expert Suggestions:

01 -
  • The vanilla sponge stays impossibly tender even days later, which means you can bake it ahead without stress.
  • White chocolate buttercream tastes like luxury but requires no complicated tempering or special skills.
  • Those edible gold balloon toppers turn a beautiful cake into a show-stopper that makes people gasp when they see it.
  • It's actually easier to decorate than it looks, which feels like a secret victory.
02 -
  • Your butter and eggs must truly be room temperature, not just slightly cool—this is how you achieve that impossibly light, fluffy crumb that feels like victory when you bite into it.
  • Don't skip the crumb coat; it's the difference between a polished-looking cake and one that looks crumb-covered and rustic (unless rustic is your goal, in which case embrace it).
  • White chocolate burns easily, so when melting it for the buttercream, use a gentle double boiler and stir constantly to avoid grainy, broken texture that no amount of cream can fix.
03 -
  • Make the cake layers up to two days ahead and store them wrapped tightly in the fridge; this actually helps them cut more cleanly and gives you time to prep everything else without stress.
  • If your kitchen is very warm, work quickly with the buttercream and use a bench scraper dipped in hot water to smooth the frosting—it melts just enough to create seamless coverage.
  • Those gold balloon toppers can be made days in advance and stored in an airtight container, so you can focus on assembly the day of serving.
