# 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. Set aside.
03 - In a large bowl using an electric mixer, cream butter and sugar until pale and fluffy, approximately 3 minutes.
04 - Beat in eggs one at a time, then add vanilla extract, mixing until fully combined.
05 - With mixer on low speed, alternate adding flour mixture and milk, beginning and ending with flour. Mix until just combined.
06 - Divide batter evenly among prepared pans, smooth tops, and bake for 30–35 minutes until a toothpick inserted in the center comes out clean.
07 - Cool cakes in pans for 10 minutes, then turn out onto wire racks and cool completely.
08 - Beat softened 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.
09 - Level cooled cakes if needed. Place first layer on serving plate, spread with buttercream, and repeat with remaining layers. Cover entire cake with a thin crumb coat and chill for 30 minutes.
10 - Apply a final thick coat of buttercream, smoothing sides and top with an offset spatula.
11 - Heat heavy cream until just simmering, then pour over chopped white chocolate. Let sit 1 minute, then stir until smooth. Cool to room temperature.
12 - 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.
13 - Spray crispy pearls or malt balls with edible gold spray or roll in luster powder. Allow to dry completely, then insert toothpicks or cake wires and arrange in a festive cluster on top of cake.
14 - Chill cake until ready to serve. Bring to room temperature before slicing.

# Helpful Hints:

01 -
  • The vanilla sponge stays impossibly moist because of the milk in the batter, which means your cake won't dry out even if you make it a day ahead.
  • White chocolate buttercream tastes like luxury but comes together in minutes if you melt the chocolate beforehand.
  • The drip looks difficult but is actually just heated cream poured over chopped chocolate—no special skills required.
  • Gold balloon decorations can be prepped while the cake bakes, so there's zero last-minute stress.
02 -
  • Room temperature ingredients are not a suggestion—cold eggs and butter will not cream properly, and you'll end up with a dense cake instead of a tender one.
  • The white chocolate in the buttercream must be completely cooled before adding it to the butter mixture, or it will melt the butter and you'll have an oily mess instead of fluffy frosting.
  • White chocolate ganache thickens as it cools, so timing is everything; if it gets too thick, gently reheat it over a double boiler until it's pourable again.
03 -
  • Invest in a turntable for frosting—it costs about fifteen dollars and transforms the process from awkward and messy to smooth and controlled.
  • Use a damp paper towel to smooth out any frosting bumps or wrinkles after you've applied the final coat; it's like magic and takes three seconds.
  • Make the white chocolate drip slightly thicker than you think you need by letting the ganache cool a few extra minutes, because thin drips absorb into the frosting and disappear instead of creating those beautiful cascades.
