Ingredients

• 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
• 2 cups (450 g) unsalted butter, room temperature (for buttercream)
• 8 cups (960 g) powdered sugar, sifted
• 1/2 cup (120 ml) whole milk or heavy cream (for buttercream)
• 2 tbsp vanilla extract (for buttercream)
• Pinch of salt (for buttercream)
• Gel food coloring (optional—for graduates colors)
• 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: Assemble layers

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 extra flavor, add lemon or almond extract to the cake batter. Use the graduate's school colors for the frosting or decorations to personalize the cake. Balloon toppers can be purchased online or made with mini balloons and cake-safe sticks. For easier assembly, chill cakes before stacking and decorating—this firms up the buttercream and makes handling much simpler. Room temperature ingredients are crucial for achieving the light, fluffy texture in both the cake and frosting. Make sure your butter, eggs, and milk have been out of the refrigerator for at least an hour before beginning. When applying the crumb coat, don't worry about perfection—this thin layer simply traps loose crumbs so your final frosting layer looks smooth and professional.

Varianten und Anpassungen

While this recipe calls for classic vanilla, you can easily adapt it to suit different tastes. Try adding a tablespoon of lemon zest to the batter for a citrus twist, or substitute half the vanilla extract with almond extract for a more sophisticated flavor profile. For chocolate lovers, replace one cup of flour with cocoa powder in the cake batter. The buttercream is equally versatile—add espresso powder for mocha frosting, fresh fruit puree for berry buttercream, or cream cheese for a tangy variation. You can also experiment with different decorations beyond balloon toppers: fresh flowers, edible gold leaf, fondant graduation caps, or piped buttercream rosettes all make beautiful alternatives. For dietary modifications, this recipe can be adapted using dairy-free butter and plant-based milk, though the texture may vary slightly.

Serviervorschläge

Present this graduation cake as the centerpiece of your dessert table, surrounded by complementary treats like cupcakes, cookies, or a fruit platter. Serve each slice with a scoop of vanilla ice cream or a dollop of freshly whipped cream for an extra indulgent touch. A drizzle of chocolate or caramel sauce adds visual appeal and flavor contrast. For beverage pairings, consider champagne or sparkling cider for toasting, coffee and tea for a classic combination, or even milkshakes for a fun, celebratory vibe. Set up a photo station near the cake so graduates can capture memories with their special dessert. Cut the cake with care, using a sharp knife dipped in hot water and wiped clean between slices to ensure neat portions that showcase the beautiful layers.
