Ingredients

• For the Vanilla Sponge Cakes: 4 1/2 cups (540 g) all-purpose flour, 3 1/2 tsp baking powder, 1/2 tsp salt, 2 1/2 cups (500 g) granulated sugar, 1 1/2 cups (340 g) unsalted butter at room temperature, 8 large eggs at room temperature, 2 tbsp pure vanilla extract, 2 cups (480 ml) whole milk at room temperature
• For the Buttercream Frosting: 2 cups (450 g) unsalted butter at room temperature, 8 cups (960 g) powdered sugar (sifted), 1/2 cup (120 ml) whole milk or heavy cream, 2 tbsp vanilla extract, pinch of salt, gel food coloring (optional—for graduate's colors)
• For Decoration: Balloon cake toppers (store-bought or homemade with food-safe sticks and mini balloons), edible confetti or sprinkles (optional)

Instructions

Step 1: Prepare the pans

Preheat your oven to 350°F (175°C). Grease and line two 8-inch (20 cm) round cake pans and two 6-inch (15 cm) round cake pans with parchment paper.

Step 2: Mix dry ingredients

In a medium bowl, whisk together flour, baking powder, and salt.

Step 3: Cream butter and sugar

In a large bowl, beat butter and sugar together until light and fluffy, about 3–5 minutes.

Step 4: Add eggs and vanilla

Add eggs one at a time, beating well after each addition. Mix in vanilla extract.

Step 5: Combine wet and dry

With the mixer on low, alternate adding the flour mixture and milk in three additions, beginning and ending with flour. Mix until just combined.

Step 6: Fill pans

Divide the batter evenly: fill the 8-inch pans and 6-inch pans with equal amounts. Tap pans gently to release air bubbles.

Step 7: Bake

Bake 8-inch cakes for 35–40 minutes and 6-inch cakes for 25–30 minutes, or until a toothpick inserted in the center comes out clean.

Step 8: Cool

Allow cakes to cool in pans for 10 minutes, then transfer to wire racks to cool completely.

Step 9: Make buttercream

Prepare the buttercream: Beat butter until creamy. Gradually add powdered sugar, beating well. Mix in vanilla, salt, and milk or cream 1 tablespoon at a time until smooth and spreadable. Tint with food coloring if desired.

Step 10: Layer cakes

Level cake tops if needed. Place one 8-inch layer on a cake board, spread a layer of buttercream, top with the second 8-inch cake. Repeat for the 6-inch cakes.

Step 11: Crumb coat

Apply a thin crumb coat of buttercream to each cake. Chill for 20 minutes.

Step 12: Final frosting and stacking

Frost cakes smoothly with remaining buttercream. Stack the 6-inch cake tier centered on top of the 8-inch tier, using dowels or straws for support if needed.

Step 13: Decorate

Decorate with balloon toppers and edible confetti or sprinkles as desired.

Zusatztipps für die Zubereitung

For easier assembly, chill your cakes thoroughly before stacking and decorating—this helps prevent crumbling and makes frosting smoother. When inserting dowels or straws for support, measure the height of the bottom tier and cut the supports to match exactly, ensuring a stable structure. If you notice air bubbles in your batter, gently tap the filled pans on the counter before baking. Room temperature ingredients are crucial for achieving the light, fluffy texture that makes this vanilla sponge so irresistible. Always sift your powdered sugar for the buttercream to avoid lumps and achieve that silky-smooth finish.

Varianten und Anpassungen

Transform this classic graduation cake to suit any preference or dietary need. For extra flavor, add lemon or almond extract to the cake batter alongside the vanilla. Personalize the frosting by tinting it with gel food coloring in the graduate's school colors—navy and gold, crimson and white, or any combination that celebrates their achievement. If you prefer a different frosting, try cream cheese buttercream or Swiss meringue buttercream for variety. For a chocolate twist, replace 1/2 cup of flour with cocoa powder in the cake batter. You can also create a three-tier version by adding a 4-inch cake on top for even more drama, or simplify to a single-tier 10-inch cake if you're serving fewer guests.

Serviervorschläge

Present this graduation cake as the stunning centerpiece of your celebration table, surrounded by matching decorations in school colors. Serve slices on festive plates alongside scoops of vanilla ice cream or fresh berries for added elegance. For a complete graduation party spread, pair the cake with sparkling punch, finger sandwiches, and a fruit platter. Consider setting up a dessert station where guests can admire the cake before cutting, complete with a commemorative cake topper featuring the graduate's name and year. If transporting the cake, assemble the tiers at your destination for stability. This cake is best enjoyed at room temperature, which allows the buttercream to achieve its creamiest texture and the vanilla flavor to shine through beautifully.
