# Cooking Directions:

01 - Preheat oven to 350°F. Grease and line three 8-inch round cake pans with parchment paper.
02 - In a bowl, whisk together flour, baking powder, and salt. Set aside.
03 - In a large mixing bowl, beat butter and sugar until light and fluffy, approximately 3 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
05 - Alternate adding the flour mixture and milk, beginning and ending with flour. Mix until just combined.
06 - Divide batter evenly among prepared pans and smooth tops.
07 - Bake for 28 to 32 minutes, or until a toothpick inserted in the center comes out clean.
08 - Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely.
09 - Combine egg whites and sugar in a heatproof bowl over simmering water. Whisk constantly until sugar dissolves and mixture reaches 160°F, approximately 5 minutes.
10 - Transfer to a stand mixer and beat on high until stiff peaks form and the bowl is cool to the touch, approximately 8 to 10 minutes.
11 - Reduce speed to medium, add butter a few cubes at a time, mixing until smooth. Add vanilla and salt.
12 - Place one cake layer on a serving plate, spread with buttercream, and repeat with remaining layers. Cover the cake with a thin crumb coat, chill for 20 minutes, then apply a final smooth layer of buttercream.
13 - Carefully apply edible gold leaf to sections of the cake using a food-safe paintbrush.
14 - Arrange edible flowers decoratively on the cake. Add a gold ribbon around the base if desired.

# Expert Suggestions:

01 -
  • The Swiss meringue buttercream tastes silky and less sweet than American buttercream, so it won't overpower the delicate flavors of the flowers.
  • Gold leaf and edible flowers are easier to work with than you'd think, and the payoff in elegance is absolutely worth those few extra minutes.
  • This cake actually tastes as impressive as it looks, with a tender crumb that people won't expect from something this showstopping.
02 -
  • If your buttercream splits or looks grainy when you add butter, it's usually because the meringue was too warm or the butter was too cold; keep mixing on low speed and it will come together.
  • Edible flowers wilt quickly once refrigerated, so add them as close to serving time as possible, or keep the cake at room temperature and chill only if absolutely necessary.
  • Gold leaf is delicate and wants to stick to everything except where you actually want it—keep your brush barely damp and your touch feather-light.
03 -
  • Make the cake layers a full day ahead and wrap them well; they'll be easier to work with and slightly more stable for stacking.
  • Keep all your ingredients at room temperature before starting—this one change prevents lumpy batter and curdled buttercream more than anything else.
  • If gold leaf intimidates you, practice on a spare plate first; you'll realize it's more forgiving than it looks once you understand how static helps it stick.
