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 (room temperature), 8 large eggs (room temperature), 2 tbsp pure vanilla extract, 2 cups (480 ml) whole milk (room temperature)
• For the Buttercream Frosting: 2 cups (450 g) unsalted butter (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 graduates 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 cakes

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 the best results, ensure all ingredients are at room temperature before you begin—this helps create a smoother batter and more even texture. When dividing batter between pans, use a kitchen scale for precision to ensure even layers. If you notice your cakes doming during baking, you can level them with a serrated knife once cooled. For easier assembly, chill cakes before stacking and decorating. The crumb coat is essential—don't skip this step as it seals in crumbs and creates a smooth foundation for your final frosting layer. When using dowels for support, cut them flush with the top of the bottom tier to ensure the upper tier sits level.

Varianten und Anpassungen

This versatile cake can be customized in countless ways to match your graduate's personality and preferences. For extra flavor, add lemon or almond extract to the cake batter for a subtle twist. Use the graduate's school colors for the frosting or decorations to make it truly personal. If you prefer chocolate, substitute 3/4 cup of the flour with cocoa powder. For a lighter option, try Swiss meringue buttercream instead of American buttercream. You can also add fresh berries between layers for a fruity surprise. Balloon toppers can be purchased online or made with mini balloons and cake-safe sticks for a custom look.

Serviervorschläge

This graduation cake serves as the perfect centerpiece for any celebration table. Present it on a decorative cake stand surrounded by fresh flowers or additional balloon decorations that complement your party theme.

This cake pairs beautifully with vanilla ice cream or fresh whipped cream. For a dessert table, consider offering it with coffee, tea, and fruit punch. The cake stays fresh covered at room temperature for up to 2 days, or refrigerated for up to 5 days—just bring to room temperature before serving for the best flavor and texture.
