# Components:

01 - 2½ cups all-purpose flour
02 - 2½ teaspoons baking powder
03 - ½ teaspoon salt
04 - 1 cup unsalted butter, room temperature
05 - 2 cups granulated sugar
06 - 4 large eggs, room temperature
07 - 1 tablespoon pure vanilla extract
08 - 1 cup whole milk, room temperature

→ White Chocolate Buttercream

09 - 1 cup unsalted butter, room temperature
10 - 4 cups powdered sugar, sifted
11 - 6 ounces white chocolate, melted and cooled
12 - 2 to 3 tablespoons heavy cream
13 - 1 teaspoon vanilla extract
14 - Pinch of salt

→ White Chocolate Drip

15 - 6 ounces white chocolate, finely chopped
16 - ¼ cup heavy cream

→ Gold Balloons Decoration

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

# Directions:

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 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 cakes 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 chopped white chocolate. Let sit for 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 remaining ganache and smooth surface.
12 - Spray crispy pearls or malt balls with edible gold spray, or roll in luster powder. Let dry completely, 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 Advice:

01 -
  • The vanilla sponge is tender enough to melt on your tongue, but sturdy enough to hold three layers without crumbling under pressure.
  • White chocolate buttercream tastes indulgent and smooth without that cloying sweetness that makes your teeth hurt.
  • The dramatic drip is actually forgiving—slight imperfections look intentional and artistic.
  • You'll feel like a professional cake decorator, even if this is your first fancy cake.
02 -
  • Room temperature ingredients are not optional—they're the difference between silky, smooth cake and one that's dense and separated.
  • The white chocolate drip will seize up if you overheat it or add cold cream to hot chocolate; always let chocolate cool slightly before adding cream, and use warm (not hot) cream.
  • Overmixing after you add the flour develops gluten and makes your cake tough, so mix on low speed and stop as soon as ingredients are just combined.
  • If your buttercream breaks and looks grainy or separated, warm it slightly over a double boiler, stirring constantly, then beat it again.
03 -
  • Invest in an offset spatula with a long, thin blade—it's the single best tool for smoothing buttercream onto cake layers and creates that polished, professional look.
  • If you're making this cake more than a few hours ahead, store the unfrosted, cooled layers in airtight containers at room temperature, then frost and decorate the day you're serving it.
  • White chocolate can be fussy about temperature, so if your buttercream seems too soft, chill it for 15 minutes and re-beat it until it's the right consistency.
  • The edible gold spray smells chemical and goes everywhere, so do it outside or in a garage with good ventilation, and wear an old shirt you don't mind getting gold specks on.
