# How-To Steps:

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 just until combined.
06 - Divide batter evenly among prepared pans. 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, about 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. Repeat with remaining layers.
13 - Cover the cake with a thin crumb coat, chill for 20 minutes, then apply a final smooth layer of buttercream.
14 - Carefully apply edible gold leaf to sections of the cake using a food-safe paintbrush.
15 - Arrange edible flowers decoratively on the cake. Add a gold ribbon around the base if desired.

# Expert Advice:

01 -
  • It looks like you hired a professional baker, but it's totally achievable in your own kitchen with the right rhythm and patience.
  • Swiss meringue buttercream is silkier and less sweet than American buttercream, making it the perfect canvas for edible flowers without tasting like pure frosting.
  • Edible gold leaf adds that undeniable wow factor that makes any achievement feel properly celebrated.
02 -
  • Egg whites must reach exactly 160°F for food safety, so use a thermometer rather than guessing; this is non-negotiable when serving to a crowd at a celebration.
  • If your buttercream breaks or looks grainy after adding butter, it usually means temperature mismatch between components, so stop mixing and let everything come closer to room temperature before trying again.
  • Edible flowers must be specifically labeled as safe for consumption and sourced from suppliers who guarantee they were grown without pesticides or harmful chemicals.
03 -
  • Make your Swiss meringue buttercream the day before and store it in an airtight container at room temperature; it will be softer and easier to spread than freshly made buttercream.
  • If you can't find fresh edible flowers, freeze-dried edible flowers work beautifully and hold their shape longer, though fresh ones photograph better for documentation of your achievement.
