# Method:

01 - Preheat oven to 350°F. Grease and line two 8-inch round cake pans and two 6-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, approximately 3 to 5 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
05 - With mixer on low speed, alternate adding the flour mixture and milk in three additions, beginning and ending with flour. Mix until just combined.
06 - Divide batter evenly between the 8-inch and 6-inch pans. Tap pans gently to release air bubbles.
07 - Bake 8-inch cakes for 35 to 40 minutes and 6-inch cakes for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean.
08 - Allow cakes to cool in pans for 10 minutes, then transfer to wire racks to cool completely.
09 - 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, and top with the second 8-inch cake. Repeat process 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.

# Expert Advice:

01 -
  • The vanilla sponge is so moist and tender that people keep asking for seconds, which never gets old to hear.
  • Two-tier means it photographs like you spent hours planning when really you just followed the steps and let the cake do the talking.
  • Balloon toppers turn this into instant celebration without requiring you to pipe intricate flowers or hand-spun sugar.
02 -
  • Room temperature ingredients are not a suggestion—they actually emulsify together into a smooth batter, while cold ingredients create separation and lumps that no amount of mixing fixes.
  • The crumb coat is the secret weapon that most home bakers skip, but it's the difference between a rustic-looking cake and one that looks intentional and polished.
03 -
  • Chill the assembled cakes in the refrigerator for at least an hour before adding final decorations, which makes everything feel more stable and prevents last-minute frosting disasters.
  • Balloon toppers can be inserted at the very last moment before serving, which means you can assemble the cake hours ahead and dress it up right before people arrive.
