# Directions:

01 - Preheat oven to 350°F. Grease and line three 8-inch round cake pans with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
03 - In a large bowl, beat butter and sugar on medium-high speed until light and fluffy, about 3 to 4 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract until fully combined.
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 level.
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, about 3 to 4 minutes.
10 - Divide buttercream into separate bowls and tint each with desired pastel gel food coloring.
11 - Place one cake layer on a serving plate, spread buttercream on top, and repeat with remaining layers.
12 - Apply a thin crumb coat of buttercream over the entire cake and chill for 20 minutes.
13 - Using piping bags fitted with various tips, decorate cake with pastel buttercreams 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 Tips:

01 -
  • The cake stays impossibly tender and moist because of the milk-and-butter combination that feels almost too simple to work.
  • Pastel buttercream feels fancy but requires nothing more than gel food coloring and a calm hand—no special piping skills needed.
  • You can make this days ahead and it only gets better as the flavors settle and mingle.
02 -
  • Room temperature ingredients are the difference between a silky batter and a grainy one—take them out of the fridge 30 minutes before you start, or set the eggs in warm water for five minutes.
  • Overmixing the batter after you add the flour will develop gluten and make your cake tough and dense, so fold gently once the ingredients are almost combined and stop immediately.
03 -
  • Level your cake layers with a serrated knife or cake leveler before frosting so they stack evenly and your final cake looks professional and stable.
  • Keep your piping bags in tall glasses while you fill them so your hands stay free and you don't accidentally squeeze frosting everywhere.
