# Directions:

01 - Preheat oven to 350°F. Grease and line three 8-inch round cake pans with parchment paper.
02 - In a mixing 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 just until combined.
06 - Divide batter evenly among prepared pans and smooth the 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 speed 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 extract and salt.
12 - Place one cake layer on a serving plate and spread with buttercream. 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 and add a gold ribbon around the base if desired.

# Expert Tips:

01 -
  • The Swiss meringue buttercream tastes like silk and actually stays smooth under your spatula, unlike frosting that separates or breaks.
  • Edible flowers and gold leaf transform a simple cake into something that photographs beautifully and tastes like you spent hours at a patisserie.
02 -
  • Egg whites absolutely must reach 160°F for food safety when making Swiss meringue buttercream; use a candy thermometer and don't estimate.
  • If your buttercream breaks or looks grainy while you're adding butter, resist the urge to throw it away—keep mixing on medium speed and it will come together smoothly within a minute or two.
03 -
  • If your Swiss meringue buttercream looks broken or curdled while you're adding butter, don't panic—keep mixing on medium speed for another minute and it will transform back into silky perfection.
  • Chill your assembled cake for at least 30 minutes before decorating with flowers and gold leaf; a firm cake is easier to handle and photographs more beautifully.
