# The Ingredients You'll Need:

→ Cake

01 - 2½ cups all-purpose flour
02 - 2½ teaspoons baking powder
03 - ½ teaspoon salt
04 - 1 cup unsalted butter, softened
05 - 2 cups granulated sugar
06 - 4 large eggs, room temperature
07 - 1 tablespoon vanilla extract
08 - 1 cup whole milk, room temperature

→ Buttercream Frosting

09 - 1½ cups unsalted butter, softened
10 - 5 cups powdered sugar, sifted
11 - 2 teaspoons vanilla extract
12 - 3-4 tablespoons whole milk or heavy cream
13 - Pinch of salt

→ Decorations

14 - Edible gold foil sheets
15 - 1 diploma-shaped cake topper
16 - Sprinkles or star confetti, optional

# Step-by-Step Instructions:

01 - Preheat oven to 350°F. Grease and line two 9-inch round cake pans with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt.
03 - In a large bowl, beat butter and sugar together until light and fluffy, about 3-4 minutes.
04 - Add eggs one at a time, beating well after each addition. Stir in vanilla extract.
05 - Alternately add flour mixture and milk to the butter mixture, beginning and ending with flour. Mix until just combined.
06 - Divide batter evenly between prepared pans and smooth the tops.
07 - Bake for 28-32 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 - Beat butter on high speed until creamy and pale, about 3 minutes. Gradually add powdered sugar, vanilla, salt, and enough milk to reach a smooth, spreadable consistency.
10 - Level cooled cakes if necessary. Place one layer on a serving plate, spread a thick layer of buttercream on top, then place second layer over it.
11 - Apply a thin crumb coat layer of frosting around the cake. Chill for 30 minutes.
12 - Frost cake smoothly with remaining buttercream.
13 - Using tweezers, carefully apply edible gold foil sheets to desired areas on the cake for a luxurious appearance.
14 - Place the diploma topper at the center or side of the cake. Add sprinkles or confetti if desired.
15 - Chill briefly to set, then serve at room temperature.

# Additional Tips::

01 -
  • The vanilla sponge is sturdy enough to handle frosting without crumbling, yet tender enough that nobody needs a knife to cut through it.
  • Edible gold foil transforms something homemade into something that looks like it came from a fancy bakery, no professional piping skills required.
  • You can bake this the day before, which means the actual decorating happens when you're fresher and the house is calmer.
  • It genuinely impresses people without demanding hours of your time on the actual celebration day.
02 -
  • Room temperature ingredients are not optional—they emulsify properly and create a more tender crumb and stable frosting than cold ingredients straight from the fridge.
  • The crumb coat (thin first layer) is what stops loose crumbs from mixing into your final frosting layer, which is the difference between a professional-looking cake and a speckled one.
  • Edible gold foil requires completely dry hands or tweezers, and even then it's delicate—accept that it might tear, and embrace the imperfect glamour as part of its charm.
  • Do not skip leveling the cake layers if they've domed during baking; a serrated knife or cake leveler makes this quick, and level layers mean a cake that won't slide around while frosting.
03 -
  • Make the cake layers the day before and wrap them tightly in plastic wrap—they'll be easier to frost when slightly less fresh and won't crumble, and the flavor actually deepens overnight.
  • If you don't have a cake turntable, place the cake on an upside-down mixing bowl on your work surface, which gives you the same rotation capability for smooth frosting.
  • Chill the frosting-covered cake for at least 30 minutes before adding the gold foil so the surface is firm and stable, preventing drag marks when you apply the delicate sheets.
  • For a foolproof diploma topper, print a small image, cut it from cardstock, laminate it, and attach it to a wooden dowel pushed gently into the cake—it's edible-adjacent and completely customizable.
