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 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.
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 a layer of buttercream on top. Repeat with remaining layers.
12 - Apply a thin layer 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 as desired.
14 - Chill for 15 to 20 minutes before serving to set the buttercream.

# Expert Tips:

01 -
  • The vanilla cake stays impossibly moist and tender, never dry or crumbly even days later.
  • Pastel buttercream gives you creative freedom without requiring advanced decorating skills—messy flowers somehow look intentional and charming.
  • It's forgiving enough for a first-time cake decorator but impressive enough to make people think you spent hours planning it.
02 -
  • Room temperature ingredients are non-negotiable—cold eggs and cold butter won't emulsify properly, and you'll end up with a separated, curdled-looking batter that bakes into a dense cake.
  • Overmixing after you add the flour is the fastest way to ruin this cake; the moment you see no flour streaks, stop the mixer and fold the last bit by hand if needed.
  • Gel food coloring changes everything—liquid food coloring makes buttercream watery and dull, while gel coloring stays concentrated and creates those true pastel shades that look like spring itself.
03 -
  • If you only have two cake pans instead of three, bake in batches—the first batch will have cooled and you can reuse the pan, creating layers that are slightly thinner but equally delicious and structurally sound.
  • The secret to smooth buttercream is sifted powdered sugar and patience; rushing the mixing or skipping the sifting step means you'll taste sandy lumps no matter how long you beat it.
