14 - Edible gold leaf sheets

# Steps to Follow:

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 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 extract 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.

# Additional Tips::

01 -
  • The Swiss meringue buttercream is so smooth and luxurious it feels like frosting clouds, and it actually holds up beautifully under those delicate flower arrangements.
  • Gold leaf turns a homemade cake into something that looks like you spent hours at a pastry academy, even though the technique is surprisingly forgiving.
  • Three vanilla layers mean you've got built-in flexibility—make it the day before, decorate the morning of, and still impress everyone at the celebration.
02 -
  • Room temperature eggs and butter aren't just suggestions—they're the difference between silky buttercream and broken, grainy frosting that looks curdled and feels gritty on your tongue.
  • The Swiss meringue step where you heat the eggs to 160°F is about food safety; don't skip it or underestimate the temperature, and use a proper thermometer, not guesswork.
  • Edible flowers must actually be edible and pesticide-free; ornamental florist flowers can be toxic, so source from grocers, farmers markets, or specialty food suppliers that guarantee safety.
  • Gold leaf is more forgiving than it looks—if you tear a sheet, just layer another piece over it, and nobody will know the difference in the final presentation.
03 -
  • Make the cake layers a full day ahead and wrap them tightly—they actually slice and frost more neatly when they're a day old, and this spreads your stress across two days instead of cramming everything into one.
  • If your buttercream breaks during mixing, don't start over; warm the bowl gently with a hair dryer or hot water, scrape the mixture back into it, and keep mixing—it almost always comes back together.
  • Gold leaf is fragile but forgiving if you're patient; let the paint brush do the work rather than pushing hard, and those tears blend into the whole rather than standing out.
