# 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 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, 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. 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 Advice:

01 -
  • It looks professional: Gold leaf and fresh flowers do the heavy lifting visually, so you look like a pastry artist even if you're not.
  • The cake tastes as good as it looks: Classic vanilla sponge paired with silky Swiss meringue buttercream means the flavors don't disappoint.
  • You can make it ahead: Bake the layers days before and decorate the morning of the celebration.
02 -
  • Never use non-edible flowers: Florist flowers are treated with chemicals; source yours from edible flower growers or farmers markets to avoid making someone sick on graduation day.
  • Room temperature is everything: Cold butter, cold eggs, and cold milk will give you a lumpy, broken batter; take 30 minutes to let ingredients warm up.
  • The Swiss meringue buttercream can break: If it looks separated or curdled when you add the butter, keep mixing on low speed; it usually smooths out within a few more minutes as the temperature evens out.
  • Gold leaf is fragile but forgiving: It adheres to buttercream easily, so don't stress about perfection; irregular placement actually looks more organic and beautiful.
03 -
  • Make a test layer: If you're nervous about the gold leaf application, practice on a small piece of buttercream or parchment paper first so you understand how delicately to handle it.
  • Invest in quality edible flowers: They make the entire cake look intentional and expensive; a few dollars spent on flowers pays off in visual impact.
  • Chill your offset spatula in ice water before final frosting: A cold spatula glides over buttercream more smoothly, giving you that bakery-quality finish.
