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 and 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.

10 - Divide buttercream into separate bowls and tint each with desired pastel gel food coloring.

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 stays impossibly moist without tasting heavy, and people always ask for seconds.
  • Buttercream that pipes like butter and tastes like clouds, giving you the confidence to create beautiful floral designs even if you've never decorated before.
  • It's forgiving enough for a first attempt but impressive enough to make you feel like a real pastry chef.
02 -
  • Room temperature ingredients are not optional—cold eggs and butter won't blend properly, and you'll end up with a batter that looks curdled and a cake that bakes unevenly.
  • Overmixing the batter after adding flour develops gluten, which makes the cake tough and dense instead of tender; mix just until you see no streaks of flour.
  • Buttercream that tastes grainy means you either didn't sift the powdered sugar or you added gel coloring too quickly without stirring it in thoroughly.
03 -
  • Level your cake layers with a long serrated knife or a cake leveler before frosting so they stack evenly and look professionally made.
  • Keep a damp kitchen towel nearby while decorating to wipe your piping tips between colors—this prevents muddy colors from bleeding together.
