# Step-by-Step Guide:

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 together 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; do not overmix.
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.
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 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 - Decorate the 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 itself is so tender and buttery that it tastes like comfort, even before you get to the frosting.
  • Decorating it becomes this meditative, creative thing—there's no pressure for perfection, just soft colors and your own interpretation of flowers.
  • It's elegant enough for a celebration but approachable enough that you won't feel like you're attempting something beyond your skill level.
02 -
  • Room temperature ingredients are not a suggestion—they make an actual difference in how smoothly everything combines and how the final cake tastes and feels in your mouth.
  • Don't overmix the batter once you've added the flour; mix just until combined, even if tiny streaks of flour are still visible, because overmixing develops gluten and creates a tough cake instead of a tender one.
03 -
  • If you only have two cake pans instead of three, bake in batches—the process takes longer but the results are identical, and rushing won't save time anyway.
  • Edible flowers or delicate sprinkles added right after the final chill will stick better and look fresher than if you add them earlier and they sit around absorbing moisture.
