1. Make the Vanilla Cake
Preheat oven to 350°F (175°C). Grease and line three 8-inch round cake pans.
Whisk together flour, baking powder, and salt.
Cream butter and sugar until fluffy, about 3–4 minutes.
Add eggs one at a time, then vanilla.
Alternate adding dry ingredients and milk, mixing gently until smooth.
Divide into pans and bake for 30–35 minutes. Cool completely before decorating.
2. Make the Buttercream
Beat butter until smooth. Add sugar gradually, then vanilla, salt, and milk to desired consistency.
Tint a portion blush pink with food coloring. Reserve white for piping or accents.
3. Assemble the Cake
Level cakes. Add buttercream between layers; you can also spread a thin layer of strawberry or raspberry jam.
Apply a crumb coat, chill for 30 minutes, then frost with pink buttercream or cover in blush-pink fondant.
4. Decorate
Place a white or rose-gold “1” on top.
Add fondant teddy bear, flower crown or bow optional.
Arrange pastel blocks spelling “ONE” or baby’s name.
Decorate with small balloon shapes, stars, and fondant flowers.
Tie a soft ribbon around the cake base for a polished finish.
