# Steps:

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.
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, avoiding overmixing.
06 - Divide batter evenly among prepared pans. Smooth the tops.
07 - Bake for 25 to 30 minutes, or until a toothpick inserted in center comes out clean.
08 - Allow cakes to cool in pans for 10 minutes, then transfer to wire rack and 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 portion with desired pastel gel food coloring.
11 - Place one cake layer on serving plate. Spread layer of buttercream on top. Repeat with remaining layers.
12 - Apply thin crumb coat of buttercream over entire cake. Chill for 20 minutes.
13 - Decorate cake with pastel buttercreams using piping bags fitted with assorted tips to create floral designs. Garnish with edible petals or sprinkles if desired.
14 - Chill for 15 to 20 minutes before serving to set buttercream.

# Expert Tips:

01 -
  • The vanilla cake stays tender and moist without fussiness, rewarding even small mixing mistakes with kindness.
  • Pastel buttercream transforms ordinary piping into something that looks like you attended culinary school but tastes like home.
  • It's forgiving enough for a birthday surprise but impressive enough to feel genuinely special.
02 -
  • Overmixing the batter is the fastest way to ruin this cake, turning it tough and dense; mix only until you can't see dry flour, then walk away.
  • Room temperature ingredients aren't a suggestion, they're essential for emulsification, so if your eggs or milk are cold, your batter will separate and your cake will suffer for it.
  • Gel food coloring is non-negotiable for pastels; liquid coloring thins the buttercream and muddies the colors, leaving you with frosting that's too soft to pipe cleanly.
03 -
  • Invest in an offset spatula if you don't have one; it transforms cake decorating from clumsy and frustrating to smooth and controlled, and it costs less than a fancy coffee.
  • If your buttercream becomes too soft while piping, pop it back in the fridge for five minutes instead of panicking and adding more powdered sugar, which will make it grainy and unworkable.
