03 - In a large bowl, beat butter and sugar on medium-high speed until light and fluffy, approximately 3 to 4 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
05 - Alternately add flour mixture and milk to butter mixture, beginning and ending with flour. Mix until just combined without overmixing.
06 - Divide batter evenly among prepared pans. Smooth the tops.
07 - Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean.
08 - Let cakes cool in pans for 10 minutes, then transfer to a wire rack to cool completely.
09 - In a large bowl, beat butter until creamy. Gradually add powdered sugar, milk, vanilla, and salt. Beat until fluffy and smooth, approximately 3 to 4 minutes.
10 - Divide buttercream into separate bowls. Tint each with desired pastel gel food coloring.
11 - Place one cake layer on a serving plate. Spread a layer of buttercream on top. Repeat with remaining layers.
12 - Apply a thin crumb coat of buttercream over the entire cake. Chill for 20 minutes.
13 - Decorate cake with pastel buttercreams using piping bags fitted with various tips to create floral designs. Garnish with edible petals or sprinkles if desired.
14 - Chill for 15 to 20 minutes before serving to set the buttercream.

# Expert Advice:

01 -
  • The vanilla cake is tender and moist without being heavy, which means it actually tastes as good as it looks.
  • Buttercream decorating feels like painting with frosting, and even small mistakes blend into the charm of homemade blooms.
  • You can adjust the colors to match any celebration or mood, making it endlessly customizable without needing special equipment.
02 -
  • Overmixing the batter after adding flour is the quickest way to a tough cake, so fold gently once you've got all ingredients combined.
  • Room temperature ingredients aren't just a suggestion—they're what separates a beautiful emulsion from a separated, broken batter.
03 -
  • If you only have two cake pans, let the first two layers cool completely, then grease and reuse the pans for the third layer—just add a few extra minutes to the bake time since the pans will be slightly warmer.
  • Lemon zest stirred into the batter or a touch of almond extract can add subtle flavor depth without changing what makes this cake special.
