Ingredients

Scale

For the Vanilla Cake (3 layers – 8-inch pans)

  • 2 ½ cups (315g) all-purpose flour
  • 2 ½ tsp baking powder
  • ½ tsp salt
  • 1 cup (226g) unsalted butter, room temp
  • 2 cups (400g) granulated sugar
  • 4 large eggs, room temp
  • 1 tbsp vanilla extract
  • 1 cup (240ml) whole milk, room temp
  • Blue gel food coloring (varying shades)

For the Buttercream

  • 1 ½ cups (340g) unsalted butter, room temp
  • 5 cups (600g) powdered sugar
  • 2–4 tbsp heavy cream or milk
  • 1 tbsp vanilla extract
  • Blue gel food coloring (light blue, medium blue, navy)

Decorations

  • Edible seashells, starfish (molds with candy melts or white chocolate)
  • Coral (melted white chocolate piped into coral shapes and hardened)
  • Crushed graham crackers (for “sand”)
  • Pearl: A white chocolate truffle or hand-molded sugar pearl
  • Pearl shell: Made from fondant or sugar paste
  • Edible shimmer dust or luster spray (optional)

Instructions

  1. Make the Cake Layers – Preheat oven to 350°F (175°C). Grease and line 3 8-inch round pans. In a bowl, whisk flour, baking powder, and salt. In another bowl, cream butter and sugar until fluffy. Add eggs one at a time, then vanilla. Add flour mixture in 3 parts, alternating with milk. Divide batter into 3 bowls. Tint each a different shade of blue. Pour each into a prepared pan and bake 25–30 mins. Cool completely.
  2. Buttercream Frosting – Beat butter until creamy. Slowly add powdered sugar. Add vanilla and cream until fluffy. Divide and tint in multiple blue shades. Apply a crumb coat, chill for 30 mins. Apply ombré or wave-like layers of buttercream (light to dark).
  3. Decorate – Shells & Starfish: Use silicone molds and white chocolate or candy melts. Dust with edible gold or pearl shimmer. Coral: Pipe melted white chocolate onto parchment in coral shapes, let harden. Sand: Sprinkle crushed graham crackers at the base. Pearl & Shell: Form an open clamshell with fondant/sugar paste. Place a truffle or candy pearl inside.

Notes

  • Use an offset spatula or palette knife for wave-like frosting textures.
  • Freeze cake layers for 30 mins before stacking to reduce crumbs.
  • For extra elegance, add a light mist of edible pearl spray for shimmer.
