# Method:
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, 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 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 cakes if needed. Place first layer on serving plate and spread with buttercream. Repeat with remaining layers. Cover entire cake with a thin crumb coat and 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 gold-dusted luster powder. Let dry completely, then insert toothpicks or cake wires and arrange in a festive cluster on top of cake.
13 - Chill cake until ready to serve. Bring to room temperature before slicing.
