    • 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

Instructions

1. 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.
2. In a medium bowl, whisk together flour, baking powder, and salt.
3. In a large bowl, beat butter and sugar together until light and fluffy, about 3–5 minutes.
4. Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
5. With the mixer on low, alternate adding the flour mixture and milk in three additions, beginning and ending with flour. Mix until just combined.
6. Divide the batter evenly: fill the 8-inch pans and 6-inch pans with equal amounts. Tap pans gently to release air bubbles.
7. 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.
8. Allow cakes to cool in pans for 10 minutes, then transfer to wire racks to cool completely.
9. 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.
10. 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.
11. Apply a thin crumb coat of buttercream to each cake. Chill for 20 minutes.
12. 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.
13. Decorate with balloon toppers and edible confetti or sprinkles as desired.

Zusatztipps für die Zubereitung

For extra flavor, consider adding lemon or almond extract to the cake batter. Using quality ingredients at room temperature will ensure your batter mixes well and bakes up moist and tender. Chilling the cakes before stacking helps in easier assembly and cleaner layers.

Varianten und Anpassungen

Customize your cake by tinting the buttercream in your graduate’s school colors using gel food coloring. Balloon toppers can be purchased online or crafted at home using mini balloons and cake-safe sticks, adding a personal touch and extra fun to the design.

Common Recipe Questions

How do I ensure the sponge stays moist?

Use room temperature ingredients and avoid overmixing the batter. Bake just until a toothpick comes out clean to retain moisture.

Can I use a different frosting?

Buttercream pairs well with this cake, but cream cheese or whipped cream frostings can also complement the flavors nicely.

What is the best way to assemble the two tiers?

Level each layer before stacking. Use dowels or straws inside the bottom tier for stability when placing the smaller tier on top.

How can I add color to the frosting?

Gel food coloring works best for vibrant hues without altering the frosting’s consistency. Customize colors to match graduation themes.

Are there any tips for decorating with balloon toppers?

Secure balloon sticks firmly in the top tier and arrange edible confetti or sprinkles around for extra festive flair.
